A couple of questions right off the bat. First, how are we going to facilitate the withdrawal of YPG units from the affected areas? I'm assuming the YPG isn't going to want to go and we kind of lost any influence we might have had when we threw them under the bus. Second, what nations around the world will be willing to work with us to secure and protect a safe zone? Nobody springs to mind and it isn't going to be us because three, President Trump has made it clear he doesn't see any role for us in the area so U.S. troops are out of the question.
Too many unknowns.
We didn’t throw them under the bus, the Turks decided to invade. The Kurdish general sent his letter making a concession to the Turks to Trump and Trump relayed that- the carrot- to the Turks along with his own comment -the stick- in the hopes the Turks would reconsider, so as to avoid the stick. Apparently it was not a big enough stick, but congress hasn’t offered Trump any support, and certainly didn’t authorize him to use force against the Turks, because they want to violate separation of powers and micromanage foreign policy, so he used what he had, Erdogan decided to gamble, and so Trump’s going to double down on sanctions and thump the Turks economically.
