Erdogen just needs to go. Period.
Turkey used to be the pleasant boundary between the West & the East. Now? Dangerous, corrupt, authoritarian, and unloyal.
They want the S400 to protect their airspace, yet wouldn't settle down & get Patriot when it was offered. They want the F-35, yet want a Russian AD system that could be used to generate intel for successful firing solutions on F-35s in the future.
It's a tricky situation, with no clear answers. They currently have hundreds of teachers, doctors, lawyers, judges, civil servants, soldiers, etc - locked up in prison, in less than stellar conditions, based on nothing more than Ergoden's "perceived" threat from them. He used a false flag coup attempt to consolidate his power, and incarcerate any potential opposition.
Until lawyers, doctors, judges, teachers, civil servants, etc etc aren't incarcerated & Egroden doesn't have the power to detain anybody he wishes, it'll be a hard sell to allow them entrance into the EU. Especially when it's still in a state of 'military disagreement' with Greece, an EU country. And when other countries that aren't members of the EU, or are more recent members of the EU, had to work extremely hard to eventually 'clean up their act' to be permitted in.
But on the other hand, we don't want them drifting more & more to the Russians...which seems to be the case.
I don't have the answer on this one, doesn't seem like an easy fix either way. (Or, just promise them membership to the EU on the conditions that they a) scrap the S-400 in favour of Patriot or similar, and b) respect rules of law, and cease the detainment of members of the judicial system who could potentially disagree with the President) :dunno:
