I think we should back off and let Russia get bogged down in a unwinable foreign war that might ruin their economy.
Short-sighted thinking. Putin is more cunning that to get bogged down. Syria will become a new base for military operations. Russia will secure more oil fields and be a game changer in the world oil market. Assad has become a puppet to Putin and POTUS is Putins' doormat. Welcome to the new world order America, how do you like your second rate status?
