I'm not sure how they fight back against tomahawk missiles.
How do you picture this going down?
Syria has the support of Iran, Russia, China and Hezbollah. I don't believe they are just going to let all their air assets just sit there and get bombed.
Israel has called up all their reserves and are passing out gas masks to their people.
Too many rogue actors in Syria for nothing to happen in the way of retaliation.
