If the current EU/ UK/ US leaders will reverse their policies on Russia, Erdogan will reverse on Syria, he's an ideologue who follows the Muslim Brotherhood doctrine, those see everybody else who is not from their cult as infidels and should be tortured and killed by the worse methods, just like the Nazis, guess who also follows the same doctrine: Al Qaeda, its head Zawahiri was one of their main figures, ISIS who took it a bit further and followed a mix of Wahhabi and Muslim Brotherhood.. These are the fringe in the Muslim world but have the most resources with the help of the British and US. Guess who is his main enemy? Syria's Assad because Assad is presumably Alawite.. It has nothing to do with politics here.

All of that comes in addition to what George W. Bush assigned to him: a leading role in the Greater Middle East (Greater Israel), he said so in an interview: https://syrianews.cc/erdogan-tool-hands-zionists/
