Yes, see my post #19.
It supports directly what you just stated.
Yes. Great minds think alike.
My guess is that the Kermlin and Erdogan are unsure of U.S. staying power with the Kurds in Syria (a wonder that Trump has encouraged with premature announcements of our eminent departures), and will do all they can to encourage our departure and so disillusionment among the Kurds.
I think Erdogan and Putin have already decided how they want to jointly control (divide) northern Syria, if the U.S. would just get out of the way.
Meanwhile the Kurds have only their own existential existence that they care about, and rightly they should as no one else in the whole region cares if the Kurds exist or not, have a place of their own or not.
