I don't give a shit, to be honest. The point is they're the enemy now. They can kiss the American ring or face the wrath. Welcome to the shrewd world of geopolitics.
Will they continue to engage in anti-American propaganda meant to instill hatred in their (rather large) population and continue to fund terrorists meant to undermine US interests? Cool. You're the enemy, then. No use crying over ancient history, who started what, etc. All that matters is this is the reality of things now, in 2016.
Are you telling me Turkey is not a perfect country and has done good and bad things? Shocking news, I was unaware. Next you're going to tell me the US, UK, Japan, etc. have all done some fucked up stuff in the past. I guess we should sever our close relations because god knows you should make long-term alliances based on that.
Turkey is a secular (fairly) democratic country. In the Middle East, that's a good thing. That means they're going to elect leaders that are sometimes one way, sometimes another. That's how it goes in a country where leaders are democratically elected and reflect the changing moods of the populace. While it's less stable in the short-term than places run by dictators, I'll ally myself with democratic countries like that over the dictatorships all day because in the long-run they're better diplomatic investments.
inbe4 someone brings up that Iran has a "democratically elected" President as if their government isn't completely incestuous and requires the approval of non-democratically appointed Islamofascists
