Syria is the cold war battlegrounds between the us and russia right now. It was convenient to let CIA create and gain power so easily, and just stroll on in to destroy the nation. Just so the US can have a legal reason to go in full on. Russia cant stop a thing now that official genicide has been declared lol. So the ally they started by defending with nukes for, they have to abandon.
And soon russia will have no legit reason to have navy in the Mediterranean.
