In 2012, the Syrians shot down a Turkish jet which had entered its airspace, and Erdogan’s furious response at the time was that “a short-term border violation can never be a pretext for an attack”.
(At the time, Nato secretary general Anders Fogh Rasmussen called it “another example of the Syrian authorities’ disregard for international norms”. There hasn’t been a similar critique of Ankara.)
