Not so long ago FSA was begging TOW missiles from the US so they could attack Assad again. Don't underestimate the treachery capable by these Arabs. I hope Turkey has learnt from its history and doesn't look at these arabs from a romantic point of view. These FSA aren't even locals I believe. Some might be but most of them are internationalist Islamists who doesn't mind to ride the American cock carousel.
I believe at some point we have to ditch FSA to come to an understanding with Assad otherwise this war will go on forever and taking out Assad is impossible with Russia and Iran having invested so much. I don't mind using these FSA as diapers. Everybody is using them so why shouldn't we? At the least we have to ditch the ones who don't listen but the question is how much of FSA will be left when we ditch the Islamists. Real Syrians who are in Turkish cities don't want to fight.
One thing is certain. We need to change some things within the FSA. Not so long ago there were some fights between fighters in Afrin. And before that they started looting. They should be thankful to Turkey. If they control any land in syria it is thanks to Turkish help but I doubt FSA fighters understand this.
