Unfortunately, they know we can't fire a single shot, because that would be us involving ourselves in endless Middle Eastern conflicts. Any actual military contact with Turkey would immediately prove Trump wrong in his assertion that we don't need to, and shouldn't, be there. That's the corner he painted us into. Turkey is conducting itself as if it's in the position of strength. The U.S. is talking withdrawal and adherence to Turkey's conditions. This is all in plain sight.
