  • The Knesset candidate who says Zionism encourages anti-Semitism and calls Netanyahu ’arch-murderer’ - Israel Election 2019 -

    Few Israelis have heard of Dr. Ofer Cassif, the Jewish representative on the far-leftist Hadash party’s Knesset slate. On April 9, that will change
    By Ravit Hecht Feb 16, 2019

    Ofer Cassif is fire and brimstone. Not even the flu he’s suffering from today can contain his bursting energy. His words are blazing, and he bounds through his modest apartment, searching frenetically for books by Karl Marx and Primo Levi in order to find quotations to back up his ideas. Only occasional sips from a cup of maté bring his impassioned delivery to a momentary halt. The South American drink is meant to help fight his illness, he explains.

    Cassif is third on the slate of Knesset candidates in Hadash (the Hebrew acronym for the Democratic Front for Peace and Equality), the successor to Israel’s Communist Party. He holds the party’s “Jewish slot,” replacing MK Dov Khenin. Cassif is likely to draw fire from opponents and be a conspicuous figure in the next Knesset, following the April 9 election.

    Indeed, the assault on him began as soon as he was selected by the party’s convention. The media pursued him; a columnist in the mass-circulation Yedioth Ahronoth newspaper, Ben-Dror Yemini, called for him to be disqualified from running for the Knesset. It would be naive to say that this was unexpected. Cassif, who was one of the first Israeli soldiers to refuse to serve in the territories, in 1987, gained fame thanks to a number of provocative statements. The best known is his branding of Justice Minister Ayelet Shaked as “neo-Nazi scum.” On another occasion, he characterized Jews who visit the Temple Mount as “cancer with metastases that have to be eradicated.”

    On his alternate Facebook page, launched after repeated blockages of his original account by a blitz of posts from right-wing activists, he asserted that Culture Minister Miri Regev is “repulsive gutter contamination,” that Prime Minister Benjamin Netanyahu is an “arch-murderer” and that the new Israel Defense Forces chief of staff, Lt. Gen. Aviv Kochavi, is a “war criminal.”

    Do you regret making those remarks?

    Cassif: “‘Regret’ is a word of emotion. Those statements were made against a background of particular events: the fence in Gaza, horrible legislation, and the wild antics of Im Tirtzu [an ultranationalist organization] on campus. That’s what I had to say at the time. I didn’t count on being in the Knesset. That wasn’t part of my plan. But it’s clear to me that as a public personality, I would not have made those comments.”

    Is Netanyahu an arch-murderer?

    “Yes. I wrote it in the specific context of a particular day in the Gaza Strip. A massacre of innocent people was perpetrated there, and no one’s going to persuade me that those people were endangering anyone. It’s a concentration camp. Not a ‘concentration camp’ in the sense of Bergen-Belsen; I am absolutely not comparing the Holocaust to what’s happening.”

    You term what Israel is doing to the Palestinians “genocide.”

    “I call it ‘creeping genocide.’ Genocide is not only a matter of taking people to gas chambers. When Yeshayahu Leibowitz used the term ‘Judeo-Nazis,’ people asked him, ‘How can you say that? Are we about to build gas chambers?’ To that, he had two things to say. First, if the whole difference between us and the Nazis boils down to the fact that we’re not building gas chambers, we’re already in trouble. And second, maybe we won’t use gas chambers, but the mentality that exists today in Israel – and he said this 40 years ago – would allow it. I’m afraid that today, after four years of such an extreme government, it possesses even greater legitimacy.

    “But you know what, put aside ‘genocide’ – ethnic cleansing is taking place there. And that ethnic cleansing is also being carried out by means of killing, although mainly by way of humiliation and of making life intolerable. The trampling of human dignity. It reminds me of Primo Levi’s ‘If This Is a Man.’”

    You say you’re not comparing, but you repeatedly come back to Holocaust references. On Facebook, you also uploaded the scene from “Schindler’s List” in which the SS commander Amon Goeth picks off Jews with his rifle from the balcony of his quarters in the camp. You compared that to what was taking place along the border fence in the Gaza Strip.

    “Today, I would find different comparisons. In the past I wrote an article titled, ‘On Holocaust and on Other Crimes.’ It’s online [in Hebrew]. I wrote there that anyone who compares Israel to the Holocaust is cheapening the Holocaust. My comparison between here and what happened in the early 1930s [in Germany] is a very different matter.”

    Clarity vs. crudity

    Given Cassif’s style, not everyone in Hadash was happy with his election, particularly when it comes to the Jewish members of the predominantly Arab party. Dov Khenin, for example, declined to be interviewed and say what he thinks of his parliamentary successor. According to a veteran party figure, “From the conversations I had, it turns out that almost none of the Jewish delegates – who make up about 100 of the party’s 940 delegates – supported his candidacy.

    “He is perceived, and rightly so,” the party veteran continues, “as someone who closes doors to Hadash activity within Israeli society. Each of the other Jewish candidates presented a record of action and of struggles they spearheaded. What does he do? Curses right-wing politicians on Facebook. Why did the party leadership throw the full force of its weight behind him? In a continuation of the [trend exemplified by] its becoming part of the Joint List, Ofer’s election reflects insularity and an ongoing retreat from the historical goal of implementing change in Israeli society.”

    At the same time, as his selection by a 60 percent majority shows, many in the party believe that it’s time to change course. “Israeli society is moving rightward, and what’s perceived as Dov’s [Khenin] more gentle style didn’t generate any great breakthrough on the Jewish street,” a senior source in Hadash notes.

    “It’s not a question of the tension between extremism and moderation, but of how to signpost an alternative that will develop over time. Clarity, which is sometimes called crudity, never interfered with cooperation between Arabs and Jews. On the contrary. Ofer says things that we all agreed with but didn’t so much say, and of course that’s going to rile the right wing. And a good thing, too.”

    Hadash chairman MK Ayman Odeh also says he’s pleased with the choice, though sources in the party claim that Odeh is apprehensive about Cassif’s style and that he actually supported a different candidate. “Dov went for the widest possible alliances in order to wield influence,” says Odeh. “Ofer will go for very sharp positions at the expense of the breadth of the alliance. But his sharp statements could have a large impact.”

    Khenin was deeply esteemed by everyone. When he ran for mayor of Tel Aviv in 2008, some 35 percent of the electorate voted for him, because he was able to touch people who weren’t only from his political milieu.

    Odeh: “No one has a higher regard for Dov than I do. But just to remind you, we are not a regular opposition, we are beyond the pale. And there are all kinds of styles. Influence can be wielded through comments that are vexatious the first time but which people get used to the second time. When an Arab speaks about the Nakba and about the massacre in Kafr Kassem [an Israeli Arab village, in 1956], it will be taken in a particular way, but when uttered by a Jew it takes on special importance.”

    He will be the cause of many attacks on the party.

    “Ahlan wa sahlan – welcome.”

    Cassif will be the first to tell you that, with all due respect for the approach pursued by Khenin and by his predecessor in the Jewish slot, Tamar Gozansky, he will be something completely different. “I totally admire what Tamar and Dov did – nothing less than that,” he says, while adding, “But my agenda will be different. The three immediate dangers to Israeli society are the occupation, racism and the diminishment of the democratic space to the point of liquidation. That’s the agenda that has to be the hub of the struggle, as long as Israel rules over millions of people who have no rights, enters [people’s houses] in the middle of the night, arrests minors on a daily basis and shoots people in the back.

    "Israel commits murder on a daily basis. When you murder one Palestinian, you’re called Elor Azaria [the IDF soldier convicted and jailed for killing an incapacitated Palestinian assailant]; when you murder and oppress thousands of Palestinians, you’re called the State of Israel.”

    So you plan to be the provocateur in the next Knesset?

    “It’s not my intention to be a provocateur, to stand there and scream and revile people. Even on Facebook I was compelled to stop that. But I definitely intend to challenge the dialogue in terms of the content, and mainly with a type of sarcasm.”

    ’Bags of blood’

    Cassif, 54, who holds a doctorate in political philosophy from the London School of Economics, teaches political science at the Hebrew University of Jerusalem, Sapir Academic College in Sderot and at the Academic College of Tel Aviv-Yaffo. He lives in Rehovot, is married and is the father of a 19-year-old son. He’s been active in Hadash for three decades and has held a number of posts in the party.

    As a lecturer, he stands out for his boldness and fierce rhetoric, which draws students of all stripes. He even hangs out with some of his Haredi students, one of whom wrote a post on the eve of the Hadash primary urging the delegates to choose him. After his election, a student from a settlement in the territories wrote to him, “You are a determined and industrious person, and for that I hold you in high regard. Hoping we will meet on the field of action and growth for the success of Israel as a Jewish, democratic state (I felt obliged to add a small touch of irony in conclusion).”

    Cassif grew up in a home that supported Mapai, forerunner of Labor, in Rishon Letzion. He was an only child; his father was an accountant, his mother held a variety of jobs. He was a news hound from an early age, and at 12 ran for the student council in school. He veered sharply to the left in his teens, becoming a keen follower of Marx and socialism.

    Following military service in the IDF’s Nahal brigade and a period in the airborne Nahal, Cassif entered the Hebrew University. There his political career moved one step forward, and there he also forsook the Zionist left permanently. His first position was as a parliamentary aide to the secretary general of the Communist Party, Meir Wilner.

    “At first I was closer to Mapam [the United Workers Party, which was Zionist], and then I refused to serve in the territories. I was the first refusenik in the first intifada to be jailed. I didn’t get support from Mapam, I got support from the people of Hadash, and I drew close to them. I was later jailed three more times for refusing to serve in the territories.”

    His rivals in the student organizations at the Hebrew University remember him as the epitome of the extreme left.

    “Even in the Arab-Jewish student association, Cassif was considered off-the-wall,” says Motti Ohana, who was chairman of Likud’s student association and active in the Student Union at the end of the 1980s and early 1990s. “One time I got into a brawl with him. It was during the first intifada, when he brought two bags of blood, emptied them out in the university’s corridors and declared, ‘There is no difference between Jewish and Arab blood,’ likening Israeli soldiers to terrorists. The custom on campus was that we would quarrel, left-right, Arabs-Jews, and after that we would sit together, have a coffee and talk. But not Cassif.”

    According to Ohana, today a member of the Likud central committee, the right-wing activists knew that, “You could count on Ofer to fall into every trap. There was one event at the Hebrew University that was a kind of political Hyde Park. The right wanted to boot the left out of there, so we hung up the flag. It was obvious that Ofer would react, and in fact he tore the flag, and in the wake of the ruckus that developed, political activity was stopped for good.”

    Replacing the anthem

    Cassif voices clearly and cogently positions that challenge the public discourse in Israel, and does so with ardor and charisma. Four candidates vied for Hadash’s Jewish slot, and they all delivered speeches at the convention. The three candidates who lost to him – Efraim Davidi, Yaela Raanan and the head of the party’s Tel Aviv branch, Noa Levy – described their activity and their guiding principles. When they spoke, there was the regular buzz of an audience that’s waiting for lunch. But when Cassif took the stage, the effect was magnetic.

    “Peace will not be established without a correction of the crimes of the Nakba and [recognition of] the right of return,” he shouted, and the crowd cheered him. As one senior party figure put it, “Efraim talked about workers’ rights, Yaela about the Negev, Noa about activity in Tel Aviv – and Ofer was Ofer.”

    What do you mean by “right of return”?

    Cassif: “The first thing is the actual recognition of the Nakba and of the wrong done by Israel. Compare it to the Truth and Reconciliation Commissions in South Africa, if you like, or with the commissions in Chile after Pinochet. Israel must recognize the wrong it committed. Now, recognition of the wrong also includes recognition of the right of return. The question is how it’s implemented. It has to be done by agreement. I can’t say that tomorrow Tel Aviv University has to be dismantled and that Sheikh Munis [the Arab village on whose ruins the university stands] has to be rebuilt there. The possibility can be examined of giving compensation in place of return, for example.”

    But what is the just solution, in your opinion?

    “For the Palestinian refugees to return to their homeland.”

    That means there will be Jews who will have to leave their home.

    “In some places, unequivocally, yes. People will have to be told: ‘You must evacuate your places.’ The classic example is Ikrit and Biram [Christian-Arab villages in Galilee whose residents were promised – untruly – by the Israeli authorities in 1948 that they would be able to return, and whose lands were turned over to Jewish communities]. But there are places where there is certainly greater difficulty. You don’t right one wrong with another.”

    What about the public space in Israel? What should it look like?

    “The public space has to change, to belong to all the state’s residents. I dispute the conception of ‘Jewish publicness.’”

    How should that be realized?

    “For example, by changing the national symbols, changing the national anthem. [Former Hadash MK] Mohammed Barakeh once suggested ‘I Believe’ [‘Sahki, Sahki’] by [Shaul] Tchernichovsky – a poem that is not exactly an expression of Palestinian nationalism. He chose it because of the line, ‘For in mankind I’ll believe.’ What does it mean to believe in mankind? It’s not a Jew, or a Palestinian, or a Frenchman, or I don’t know what.”

    What’s the difference between you and the [Arab] Balad party? Both parties overall want two states – a state “of all its citizens” and a Palestinian state.

    “In the big picture, yes. But Balad puts identity first on the agenda. We are not nationalists. We do not espouse nationalism as a supreme value. For us, self-determination is a means. We are engaged in class politics. By the way, Balad [the National Democratic Assembly] and Ta’al [MK Ahmad Tibi’s Arab Movement for Renewal] took the idea of a state of all its citizens from us, from Hadash. We’ve been talking about it for ages.”

    If you were a Palestinian, what would you do today?

    “In Israel, what my Palestinian friends are doing, and I with them – [wage] a parliamentary and extra-parliamentary struggle.”

    And what about the Palestinians in the territories?

    “We have always been against harming innocent civilians. Always. In all our demonstrations, one of our leading slogans was: ‘In Gaza and in Sderot, children want to live.’ With all my criticism of the settlers, to enter a house and slaughter children, as in the case of the Fogel family [who were murdered in their beds in the settlement of Itamar in 2011], is intolerable. You have to be a human being and reject that.”

    And attacks on soldiers?

    “An attack on soldiers is not terrorism. Even Netanyahu, in his book about terrorism, explicitly categorizes attacks on soldiers or on the security forces as guerrilla warfare. It’s perfectly legitimate, according to every moral criterion – and, by the way, in international law. At the same time, I am not saying it’s something wonderful, joyful or desirable. The party’s Haifa office is on Ben-Gurion Street, and suddenly, after years, I noticed a memorial plaque there for a fighter in Lehi [pre-state underground militia, also known as the Stern Gang] who assassinated a British officer. Wherever there has been a struggle for liberation from oppression, there are national heroes, who in 90 percent of the cases carried out some operations that were unlawful. Nelson Mandela is today considered a hero, he was awarded the Nobel Peace Prize, but according to the conventional definition, he was a terrorist. Most of the victims of the ANC [African National Congress] were civilians.”

    In other words, today’s Hamas commanders who are carrying out attacks on soldiers will be heroes of the future Palestinian state?

    “Of course.”

    Anti-Zionist identity

    Cassif terms himself an explicit anti-Zionist. “There are three reasons for that,” he says. “To begin with, Zionism is a colonialist movement, and as a socialist, I am against colonialism. Second, as far as I am concerned, Zionism is racist in ideology and in practice. I am not referring to the definition of race theory – even though there are also some who impute that to the Zionist movement – but to what I call Jewish supremacy. No socialist can accept that. My supreme value is equality, and I can’t abide any supremacy – Jewish or Arab. The third thing is that Zionism, like other ethno-nationalistic movements, splits the working class and all weakened groups. Instead of uniting them in a struggle for social justice, for equality, for democracy, it divides the exploited classes and the enfeebled groups, and by that means strengthens the rule of capital.”

    He continues, “Zionism also sustains anti-Semitism. I don’t say it does so deliberately – even though I have no doubt that there are some who do it deliberately, like Netanyahu, who is connected to people like the prime minister of Hungary, Viktor Orban, and the leader of the far right in Austria, Hans Christian Strache.”

    Did Mapai-style Zionism also encourage anti-Semitism?

    “The phenomenon was very striking in Mapai. Think about it for a minute, not only historically, but logically. If the goal of political and practical Zionism is really the establishment of a Jewish state containing a Jewish majority, and for Diaspora Jewry to settle there, nothing serves them better than anti-Semitism.”

    What in their actions encouraged anti-Semitism?

    “The very appeal to Jews throughout the world – the very fact of treating them as belonging to the same nation, when they were living among other nations. The whole old ‘dual loyalty’ story – Zionism actually encouraged that. Therefore, I maintain that anti-Semitism and anti-Zionism are not the same thing, but are precisely opposites. That doesn’t mean, of course, that there are no anti-Zionists who are also anti-Semites. Most of the BDS people are of course anti-Zionists, but they are in no way anti-Semites. But there are anti-Semites there, too.”

    Do you support BDS?

    “It’s too complex a subject for a yes or no answer; there are aspects I don’t support.”

    Do you think that the Jews deserve a national home in the Land of Israel?

    “I don’t know what you mean by ‘national home.’ It’s very amorphous. We in Hadash say explicitly that Israel has a right to exist as a sovereign state. Our struggle is not against the state’s existence, but over its character.”

    But that state is the product of the actions of the Zionist movement, which you say has been colonialist and criminal from day one.

    “That’s true, but the circumstances have changed. That’s the reason that the majority of the members of the Communist Party accepted the [1947] partition agreement at the time. They recognized that the circumstances had changed. I think that one of the traits that sets communist thought apart, and makes it more apt, is the understanding and the attempt to strike the proper balance between what should be, and reality. So it’s true that Zionism started as colonialism, but what do you do with the people who were already born here? What do you tell them? Because your grandparents committed a crime, you have to leave? The question is how you transform the situation that’s been created into one that’s just, democratic and equal.”

    So, a person who survived a death camp and came here is a criminal?

    “The individual person, of course not. I’m in favor of taking in refugees in distress, no matter who or what they are. I am against Zionism’s cynical use of Jews in distress, including the refugees from the Holocaust. I have a problem with the fact that the natives whose homeland this is cannot return, while people for whom it’s not their homeland, can, because they supposedly have some sort of blood tie and an ‘imaginary friend’ promised them the land.”

    I understand that you are in favor of the annulment of the Law of Return?

    “Yes. Definitely.”

    But you are in favor of the Palestinian right of return.

    “There’s no comparison. There’s no symmetry here at all. Jerry Seinfeld was by chance born to a Jewish family. What’s his connection to this place? Why should he have preference over a refugee from Sabra or Chatila, or Edward Said, who did well in the United States? They are the true refugees. This is their homeland. Not Seinfeld’s.”

    Are you critical of the Arabs, too?

    “Certainly. One criticism is of their cooperation with imperialism – take the case of today’s Saudi Arabia, Qatar and so on. Another, from the past, relates to the reactionary forces that did not accept that the Jews have a right to live here.”

    Hadash refrained from criticizing the Assad regime even as it was massacring civilians in Syria. The party even torpedoed a condemnation of Assad after the chemical attack. Do you identify with that approach?

    “Hadash was critical of the Assad regime – father and son – for years, so we can’t be accused in any way of supporting Assad or Hezbollah. We are not Ba’ath, we are not Islamists. We are communists. But as I said earlier, the struggle, unfortunately, is generally not between the ideal and what exists in practice, but many times between two evils. And then you have to ask yourself which is the lesser evil. The Syrian constellation is extremely complicated. On the one hand, there is the United States, which is intervening, and despite all the pretense of being against ISIS, supported ISIS and made it possible for ISIS to sprout.

    "I remind you that ISIS started from the occupation of Iraq. And ideologically and practically, ISIS is definitely a thousand times worse than the Assad regime, which is at base also a secular regime. Our position was and is against the countries that pose the greatest danger to regional peace, which above all are Qatar and Saudi Arabia, and the United States, which supports them. That doesn’t mean that we support Assad.”

    Wrong language

    Cassif’s economic views are almost as far from the consensus as his political ideas. He lives modestly in an apartment that’s furnished like a young couple’s first home. You won’t find an espresso maker or unnecessary products of convenience in his place. To his credit, it can be said that he extracts the maximum from Elite instant coffee.

    What is your utopian vision – to nationalize Israel’s conglomerates, such as Cellcom, the telecommunications company, or Osem, the food manufacturer and distributor?

    “The bottom line is yes. How exactly will it be done? That’s an excellent question, which I can’t answer. Perhaps by transferring ownership to the state or to the workers, with democratic tools. And there are other alternatives. But certainly, I would like it if a large part of the resources were not in private hands, as was the case before the big privatizations. It’s true that it won’t be socialism, because, again, there can be no such thing as Zionist socialism, but there won’t be privatization like we have today. What is the result of capitalism in Israel? The collapse of the health system, the absence of a social-welfare system, a high cost of living and of housing, the elderly and the disabled in a terrible situation.”

    Does any private sector have the right to exist?

    “Look, the question is what you mean by ‘private sector.’ If we’re talking about huge concerns that the owners of capital control completely through their wealth, then no.”

    What growth was there in the communist countries? How can anyone support communism, in light of the grim experience wherever it was tried?

    “It’s true, we know that in the absolute majority of societies where an attempt was made to implement socialism, there was no growth or prosperity, and we need to ask ourselves why, and how to avoid that. When I talk about communism, I’m not talking about Stalin and all the crimes that were committed in the name of the communist idea. Communism is not North Korea and it is not Pol Pot in Cambodia. Heaven forbid.”

    And what about Venezuela?

    “Venezuela is not communism. In fact, they didn’t go far enough in the direction of socialism.”

    Chavez was not enough of a socialist?

    “Chavez, but in particular Maduro. The Communist Party is critical of the regime. They support it because the main enemy is truly American imperialism and its handmaidens. Let’s look at what the U.S. did over the years. At how many times it invaded and employed bullying, fascist forces. Not only in Latin America, its backyard, but everywhere.”

    Venezuela is falling apart, people there don’t have anything to eat, there’s no medicine, everyone who can flees – and it’s the fault of the United States?

    “You can’t deny that the regime has made mistakes. It’s not ideal. But basically, it is the result of American imperialism and its lackeys. After all, the masses voted for Chavez and for Maduro not because things were good for them. But because American corporations stole the country’s resources and filled their own pockets. I wouldn’t make Chavez into an icon, but he did some excellent things.”

    Then how do you generate individual wealth within the method you’re proposing? I understand that I am now talking to you capitalistically, but the reality is that people see the accumulation of assets as an expression of progress in life.

    “Your question is indeed framed in capitalist language, which simply departs from what I believe in. Because you are actually asking me how the distribution of resources is supposed to occur within the capitalist framework. And I say no, I am not talking about resource distribution within a capitalist framework.”

    Gantz vs. Netanyahu

    Cassif was chosen as the polls showed Meretz and Labor, the representatives of the Zionist left, barely scraping through into the next Knesset and in fact facing a serious possibility of electoral extinction. The critique of both parties from the radical left is sometimes more acerbic than from the right.

    Would you like to see the Labor Party disappear?

    “No. I think that what’s happening at the moment with Labor and with Meretz is extremely dangerous. I speak about them as collectives, because they contain individuals with whom I see no possibility of engaging in a dialogue. But I think that they absolutely must be in the Knesset.”

    Is a left-winger who defines himself as a Zionist your partner in any way?

    “Yes. We need partners. We can’t be picky. Certainly we will cooperate with liberals and Zionists on such issues as combating violence against women or the battle to rescue the health system. Maybe even in putting an end to the occupation.”

    I’ll put a scenario to you: Benny Gantz does really well in the election and somehow overcomes Netanyahu. Do you support the person who led Operation Protective Edge in Gaza when he was chief of staff?

    “Heaven forbid. But we don’t reject people, we reject policy. I remind you that it was [then-defense minister] Yitzhak Rabin who led the most violent tendency in the first intifada, with his ‘Break their bones.’ But when he came to the Oslo Accords, it was Hadash and the Arab parties that gave him, from outside the coalition, an insurmountable bloc. I can’t speak for the party, but if there is ever a government whose policy is one that we agree with – eliminating the occupation, combating racism, abolishing the nation-state law – I believe we will give our support in one way or another.”

    And if Gantz doesn’t declare his intention to eliminate the occupation, he isn’t preferable to Netanyahu in any case?

    “If so, why should we recommend him [to the president to form the next government]? After the clips he posted boasting about how many people he killed and how he hurled Gaza back into the Stone Age, I’m far from certain that he’s better.”

      Le candidat à la Knesset dit que le sionisme encourage l’antisémitisme et qualifie Netanyahu de « meurtrier »
      Peu d’Israéliens ont entendu parler de M. Ofer Cassif, représentant juif de la liste de la Knesset du parti d’extrême gauche Hadash. Le 9 avril, cela changera.
      Par Ravit Hecht 16 février 2019 – Haaretz

      (…) Identité antisioniste
      Cassif se dit un antisioniste explicite. « Il y a trois raisons à cela », dit-il. « Pour commencer, le sionisme est un mouvement colonialiste et, en tant que socialiste, je suis contre le colonialisme. Deuxièmement, en ce qui me concerne, le sionisme est raciste d’idéologie et de pratique. Je ne fais pas référence à la définition de la théorie de la race - même si certains l’imputent également au mouvement sioniste - mais à ce que j’appelle la suprématie juive. Aucun socialiste ne peut accepter cela. Ma valeur suprême est l’égalité et je ne peux supporter aucune suprématie - juive ou arabe. La troisième chose est que le sionisme, comme d’autres mouvements ethno-nationalistes, divise la classe ouvrière et tous les groupes sont affaiblis. Au lieu de les unir dans une lutte pour la justice sociale, l’égalité, la démocratie, il divise les classes exploitées et affaiblit les groupes, renforçant ainsi le pouvoir du capital. "
      Il poursuit : « Le sionisme soutient également l’antisémitisme. Je ne dis pas qu’il le fait délibérément - même si je ne doute pas qu’il y en a qui le font délibérément, comme Netanyahu, qui est connecté à des gens comme le Premier ministre de la Hongrie, Viktor Orban, et le chef de l’extrême droite. en Autriche, Hans Christian Strache. ”

      Le sionisme type-Mapaï a-t-il également encouragé l’antisémitisme ?
      « Le phénomène était très frappant au Mapai. Pensez-y une minute, non seulement historiquement, mais logiquement. Si l’objectif du sionisme politique et pratique est en réalité de créer un État juif contenant une majorité juive et de permettre à la communauté juive de la diaspora de s’y installer, rien ne leur sert mieux que l’antisémitisme. "

      Qu’est-ce qui, dans leurs actions, a encouragé l’antisémitisme ?

  • If China Galvanized Steel Roofing Sheet for sale is used for too long or not used for a long time, it may age. Why do you say that long-term construction or storage must be exposed to the sun? After a long period of exposure to light, aging will occur, which we can’t avoid, but we can prevent the speed of aging in advance, so what should we do?

    The first necessary condition for the aging or photochemical reaction of the color-coated plate is that the surface component of the low price color corrugated steel sheet can absorb the radiant energy; secondly, when the radiant energy absorbed by the molecule is greater than the molecular bond energy, the coating of the color-coated plate can be degraded. The shorter the wavelength of the light, the higher the energy it contains.

    According to the above theory, the aging of the low price color corrugated steel sheet in the atmospheric environment is that the coating molecule absorbs energy in the ultraviolet light band of the solar light higher than its molecular bond energy, resulting in degradation of the coating molecule. As the coating film ages, the base body gradually loses, and the surface of the coating gradually becomes rough and loses light. This loss of the binder ultimately leaves relatively stable pigment particles which remain as unbonded powder on the surface of the coating film, a process known as pulverization.

    In summary, polyester coatings with different coating thicknesses have great differences in aging resistance, thin coatings have poor aging resistance, and normal aging coatings have relatively good aging resistance.

    Therefore, the method of reducing the production cost of the color-coated plate by reducing the coating is not feasible, which will inevitably bring serious quality problems. At the same time, it also demonstrates from the side that the coating thickness of the foreign cheap color corrugated steel sheet in stock importer clearly indicates the coating thickness.

  • China’s Old Oil Guard Dabble in Wind Power as ’We Know’ Offshore - Bloomberg

    _Photographer: Eric Thayer/Bloomberg

    China’s offshore oil and gas experts are dipping their toes in wind power, bringing their experience working on the ocean floor and adding a new twist to their portfolios.

    Cnooc Ltd., the country’s top offshore oil explorer, said it wants to use its expertise in marine geology to replicate its success in the offshore wind sector. The company entered its first offshore wind project in Jiangsu province this month. China Oilfield Services Ltd. echoed that view, saying its experience operating in deep waters offers a competitive advantage as the company looks for more contracts in offshore wind services.

    When we see opportunities in building offshore wind farms, we know immediately it would be an easy task for us,” Qi Meisheng, chairman of China Oilfield, told reporters on Thursday. “We know offshore geology, we know how to drill and we know how to make the process go as smoothly as it can be.

    China is turning to renewable power to aid its fight against the pollution that blights the world’s most populous nation. Wind is the country’s third-largest source of energy behind coal and hydro.

    Consultancy Wood Mackenzie Ltd. predicts an almost 10-fold surge in China’s offshore wind capacity to 33 gigawatts by 2027. Government targets will drive development, but the lack of technical expertise will present a hurdle, said Robert Liew, a senior analyst at Woodmac.

  • DAVOS-Big Oil is more talk than action on renewables - Iberdrola | Reuters

    The world’s largest wind-power producer, Iberdrola SA, has brushed off Big Oil’s embrace of renewable energy as “more noise” than action.

    Major oil and gas firms have been venturing into renewable power under pressure from climate-change policy, collectively spending around 1 percent of their 2018 budgets on clean energy, according to a recent study by research firm CDP.

    However, Iberdrola Chief Executive Ignacio Galan, who has led the Spanish utility for 17 years, shrugged when asked in a Reuters interview if Big Oil represented a competitive threat.

    It’s good that they have moved in this direction but they make more noise than the reality,” he said on Thursday on the sidelines of the World Economic Forum in Davos, Switzerland.

    Galan said returns on oil investment still far exceeded those typical of wind and solar projects and he doubted major oil companies would make a meaningful shift until that changed.

    They like to be enthusiastic but if they had to make a choice between a wonderful oil well and a good wind farm, I feel their heart will move in the traditional direction.
    He said U.S. states were more influential than Washington in terms of energy investment, and that several were looking to develop America’s first offshore wind farms, from Massachusetts down to North Carolina and New York across to California.

    The states are more and more committed to moving to renewables and the same is true of the cities and towns,” he said, adding that falling generation costs of renewable energy was a big driver of the U.S. adoption of wind and solar power.

    U.S. judge blocks Atlantic seismic oil permitting during shutdown | Reuters

    A federal court judge on Friday ruled that the federal government cannot process seismic testing permits for offshore oil drilling during the ongoing government shutdown, dealing a blow Trump administration’s energy agenda.

    Judge Richard Gergel of the U.S. District Court in South Carolina issued the decision in response to a motion filed by a range of conservation and business groups and coastal cities opposed to the administration’s efforts to expand U.S. offshore drilling.

    The Justice Department had sought a delay in the court proceedings arguing that it did not have the resources it needed to work on the case during the shutdown.

    Gergel said in his decision that he would grant the stay, but said federal authorities cannot work on seismic permitting until the government re-opens and is funded.

  • Huge Solar Farms to ‘Match’ Google Data Center Energy Use in Southeast

    As the world’s largest corporate buyer of renewable energy, Google has been leading the charge by tech giants to make their data center energy use carbon-neutral. Those efforts have resulted in a massive amount of new renewable generation capacity to be built in the US and Europe, and at least one project in South America.
    Alphabet/Google/Aerial Innovations

    Google data center under construction in Clarksville, Tennessee

    “Last year, we shared our long-term objective to source carbon-free electricity around the clock for each of our data centers,” Amanda Corio, Google’s senior lead for energy and infrastructure, wrote in a blog post announcing the latest solar projects. “These new solar projects will bring us substantially closer to that goal in the Southeastern US.”

    In a deal with the Tennessee Valley Authority, the company has agreed to buy the two new solar farm’s entire output. It didn’t say where the remaining power in the 413MW renewable energy deal would come from. Each of the solar farms described in the blog post is expected to have generation capacity of about 150MW.

    Since it’s not always possible to power a data center directly with renewable energy generated by a specific wind or solar farm, Google’s focus has been on “matching” its energy consumption with renewables. That means that it buys a kilowatt hour of energy from a renewable source built specifically for Google for every kilowatt hour of energy consumed by its data centers, Urs Hölzle, Google’s senior VP of technical infrastructure, explained in a blog post last year:

    We say that we “matched” our energy usage because it’s not yet possible to “power” a company of our scale by 100 percent renewable energy. It’s true that for every kilowatt-hour of energy we consume, we add a matching kilowatt-hour of renewable energy to a power grid somewhere. But that renewable energy may be produced in a different place, or at a different time, from where we’re running our data centers and offices. What’s important to us is that we are adding new clean energy sources to the electrical system, and that we’re buying that renewable energy in the same amount as what we’re consuming, globally and on an annual basis.

    The new solar projects in Hollywood, Alabama, and Yum Yum, Tennessee, will be built by NextEra Energy Resources and Invenergy, which partner with TVA. By buying their output, Google expects to match the energy consumption of its upcoming data centers in the region with renewables “from day one.”

    Equinor has won a license to develop carbon dioxide (CO2) storage under the North Sea, Norway’s oil ministry said on Friday, part of a push to combat climate change.

    Equinor is expected to submit a development plan this year, with parliament making a final decision in 2020 or 2021.

    Proponents of carbon capture and storage (CCS) say countries need the technology to help fulfil pledges made around the time of the breakthrough Paris climate change agreement in 2015.

    But environmentalists say is a costly technology that will perpetuate the status quo when rapid and deep cuts to energy use are needed to limit global warming.

  • Driven by rear shaft of tractor or Electric Motor Peanut picker machine performance?
    Driven by rear shaft of tractor or Electric Motor Peanut picker machine is one of the equipment that is often used in agricultural production today. How much do you know about this equipment? Do you know some of the performance and installation of this device? Come and summarize it for everyone today.
    Driven by rear shaft of tractor or Electric Motor Peanut picker machine performance:
    The electric peanut picker is mainly powered by small tractors and electric motors and sells the picked peanuts directly through the conveyor bag.
    Working process: Peanut oysters carrying peanuts are separated into peanut pickers by full feeding, and peanuts and cockroaches are automatically separated by rotation of the machine. The separated peanuts land on the vibrating screen and the mixed leaves and weeds are simultaneously blown to the outside by the fan, and the remaining crucible is discharged from the discharge port. In this process, the peanut breakage rate is less than 2%, and the processed peanuts are processed. Clean and complete, processed peanuts, clean, no peanuts, leaves, branches and other fruit breakage rate of less than 2%. The set of products is simple and flexible to operate, easy to use and low in damage rate. It reduces the labor burden of farmers’ friends, which saves labor, saves time and energy, and is highly efficient. It is the ideal machine for most farmers to harvest peanuts. Farmers are welcome to buy and use.

  • A mathematical approach for understanding intra-plant communication

    A team of researchers at the Gran Sasso Science Institute (GSSI) and Istituto Italiano di Technologia (IIT) have devised a mathematical approach for understanding intra-plant communication. In their paper, pre-published on bioRxiv, they propose a fully coupled system of non-linear, non-autonomous discontinuous and ordinary differential equations that can accurately describe the adapting behavior and growth of a single plant, by analyzing the main stimuli affecting plant behavior.

    Recent studies have found that rather than being passive organisms, plants can actually exhibit complex behaviors in response to environmental stimuli, for instance, adapting their resource allocation, foraging strategies, and growth rates according to their surrounding environment. How plants process and manage this network of stimuli, however, is a complex biological question that remains unanswered.

    Researchers have proposed several mathematical models to achieve a better understanding of plant behavior. Nonetheless, none of these models can effectively and clearly portray the complexity of the stimulus-signal-behavior chain in the context of a plant’s internal communication network.

    The team of researchers at GSSI and IIT who carried out the recent study had previously investigated the mechanisms behind intra-plant communication, with the aim to identify and exploit basic biological principles for the analysis of plant root behavior. Their previous work analyzed robotic roots in a simulated environment, translating a set of biological rules into algorithmic solutions.

    Even though each root acted independently from the others, the researchers observed the emergence of some self-organizing behavior, aimed at optimizing the internal equilibrium of nutrients at the whole-plant level. While this past study yielded interesting results, it merely considered a small part of the complexity of intra-plant communication, completely disregarding the analysis of above-ground organs, as well as photosynthesis-related processes.
    In this paper, we do not aspire to gain a complete description of the plant complexity, yet we want to identify the main cues influencing the growth of a plant with the aim of investigating the processes playing a role in the intra-communication for plant growth decisions,” the researchers wrote in their recent paper. “We propose and explain here a system of ordinary differential equations (ODEs) that, differently from state of the art models, take into account the entire sequence of processes from nutrients uptake, photosynthesis and energy consumption and redistribution.

    • Plant behaviour: A mathematical approach for understanding intra-plant communication | bioRxiv (pdf en ligne)

      Plants are far from being passive organisms being able to exhibit complex behaviours in response to environmental stimuli. How these stimuli are combined, triggered and managed is still an open and complex issue in biology. Mathematical models have helped in understanding some of the pieces in the complexity of intra-plant communication, but a larger and brighter view, setting together multiple key processes, is still missing. This paper proposes a fully coupled system of nonlinear, non-autonomous, discontinuous, ordinary differential equations to describe with accuracy the adapting behaviour and growth of a single plant, by deeply analysing the main stimuli affecting plant behaviour. The proposed model was developed, and here sustained, with the knowledge at the state of the art; and validated with a comparison among numerical results and a wide number of biological data collected from the literature, demonstrating its robustness and reliability. From the proposed analysis it is also shown an emerging self-optimisation of internal resources and feedback stimuli, without the need for defining an optimisation function for the wellness of the plant. The model is ultimately able to highlight the stimulus-signal of the intra-communication in plant, and it can be expanded and adopted as useful tool at the crossroads of disciplines as mathematics, robotics, biology, for instance for validation of biological hypothesis, translation of biological principles into control strategies or resolution of combinatorial problems.
