What will likely happen? My 2 cents worth. First off nobody wants boots on the ground, so an air strike is all that’s left. Next bombing civilians would be a big no no, so surgical strikes on military targets are most likely. Syria cannot really retaliate because it will escalate the conflict beyond their control. They will hem and haw, but do nothing, but perhaps use propaganda to decry baby killing, or some such. Now for the other players. Israel will stay out of it as will Turkey, and Iran. As for China, they backed down over Snowden so they will back down again. Now for Russia, they will stir the pot, and keep the fire hot. They have the most to gain if the conflict continues and even expands, without their direct involvement that is. Every day oil prices stay high Russia digs its way out of the hole she put herself in during the cold war. And every day the US and her allies are at war in the middle east, they dig their financial holes deeper. So Russia will not stop the madness if anything they will sell weapons to Syria, and Iran and laugh all the way to the bank. Obama gets his war, the military industrial complex gets its kickbacks, and you and I foot the bill once again. Just my 2 cents CTHorner.
