Without air power, how can the air Force of a sovereign Nation defeat the terrorists? I have seen no proof that Assad did a chemical attack. This change in policy is 100% neocon.
The issue is Not one of the nation leaders fighting there wants anyone to use chemicals weapons. Easy as pie to get their approval to take out those bases where they were launched.
I don’t believe Assad did it wither..the terrorists always use them when they’re loosing. But all involved there are going to try and safe face for this war by whatever story they want to project..including us.
