I don't think Russia will give up on Syria and Assad. They have no reason to. They know how divided our nation is on Trump and they will use that. They got the leverage, not us. Divided nation is a weak nation. All they have to do is put some Russian boots on the ground at the airfields, and the Syrians can continued to gas their own people in their own civil war. Syria and Syrians are not worth a war with Russia.
