Oh, when I say treat Turkey as a Dictatorship, I mean that historically when the US gets in a political disagreement with a foreign power, they can put targeted economic sanctions on the dictator and their family - minimal impact on the country's economy (starving them doesn't work, we've been trying for years elsewhere).
Now, our reasons for applying the sanctions are usually pretty shitty, but hey, I can dream.
Ah I see. But leaving troops where they were, Turkey was going to attack no matter what sanctions or not. So even with sanctions on their leader and top generals and what not, that wouldn't have solved the solution short term. Turkey was moving troops immedietly to the area and was going to attack no matter what anyone did. So they'd also kill US troops if they got left there, wouldn't care (short term) about sanctions and killing troops be a direct conflict. So turkey apparently gave little notice (though I recall a month or two ago reports of a large turkish army build up on border of syria), so there was little that could be done except to leave without getting into a conflict. And turkey even said they'd kill anyone there, US troops or not. So they seemed itching for a fight.
Long term sanctions may be good, may even been better 1-2 months ago with the army build up. but that wouldn't have made the leader of turkey change his mind about invading part of syria. That seemed like a done deal no matter what. Turkey repeatedly said they were going to get rid of "terrorists" no matter what US did.
(edit: Again I don't approve of abandoning on ally, it will only make other countries more likely to join china or russia in an alliance. But leaving troops there for turkey to kill doesn't seem very smart. I do approve of sanctions against them, but that wouldn't really help the kurds out without military backup and again that would lead to a ground conflict. But outside of sanctions, don't see a better solution to that. I just don't think turkey would care about sanctions enough to stop their plan of moving into syria. China and russia also apparently don't care about sanctions either, but at least I do agree it be something.
(edit 2: It been a bit late for sanctions by time turkey warned everyone (even though there was satellite imagery of build up from way before their warning), so was a bit late for that. But if trump wasn't racist and not so stupid, any president would have start dealing with the issue months ago. He probably hates the kurds tbh. But turkey is majority muslim too, so I dunno its weird. Trump seems to hate the kurds more for some reason. I never got a sense he cared about them over there. That is probably the real reason trump has never done anything to help them. granted I still don't think a war is good and I hate wars, but a good president would have handled it and tried more peaceful routes. Even if turkey was gonna do it no matter what, most presidents would still have tried. Trump never even tried for a peaceful route.
