Although this assassination is a significant second blow to Turkish-Russian relations after the downing of the Russian jet, it is unlikely to impair these relations. Assessments of a World War III or analogies of Archduke Franz Ferdinand are also quite out of proportion.
If anything, it will increase intelligence and security partnership between the two countries. Yet, the incident impairs Ankara’s ability to diplomatically pressure Russia either on the Aleppo evacuation, or its aftermath, or the role of Iran in post-war Syria.
And finally, it opens up more extensive pressuring channels for Moscow to force Ankara to end any and all proxy relations in Syria, effectively cutting off Ankara from Aleppo or its aftermath.
