Personally, I think CIA agents triggered the civil war in Syria. America wants to weaken Assad and by that weaken Russia as well, since Russia supports Assad. Russia needs that harbour which he rents from Assad. So they're 'friends' if you will. America's only interested in the oil there and weakening Russia. Furthermore if there's any kind of war, then America can sell weapons as well and it's a huge business. But I agree with you on that the superpowers should've left the Middle East alone!
