I have a really hard time thinking he will do anything. He knows that if things go wrong, he will have to deal with it later, and if this president does anything he thinks about the way he will be thought of, in the future.
If he does anything, it will probably be the light strikes that Bill Clinton ordered.
He has now realized what the past speeches will do, to bite you in the rear. If he is not careful, he will end up doing what Bush did.
The gas attacks are horrible, no matter who is doing it, but if the past is true, it will not effect his decision, because when there were gas attacks in Iraq, he condemned the president for doing something about it.
I agree AR, the red line was a big mistake, which I'll bet he regrets.
