1) chemical weapons - bad
2) Hitler, Sadam - bad
3) Assad is responsible and we must send a message - good.

Oh, and when we bomb, are we allowed to kill up to, but not over the 1,429 people killed by chemical weapons? What about our method of killing them... Can we burn them alive with napalm? That would certainly send a message.
I disagree with Juan, but I do give him credit for answering the questions.
