The Arab League has urged the UN to take action against Syria:

Their pleas will probably fall on deaf ears in the Security Council (Russia, China).
If non-US PFers haven't picked up on it, there is a growing sentiment in the US to just keep out of the business of other countries. More specifically, Americans ask, "Why us? Why are WE the world's police?"
The Arab League's members have more than enough resources to take care of this themselves. So what if they did? Could the US, France, and maybe the UK give them cover in the UN?
Personally, I back Obama on his views on this, that it's an atrocity that must not be shrugged off. I'm weary as hell of war but I can't believe the world is willing to let this go unpunished. I can only hope that we won't look back on this in 30 years and just hang our heads in regret. So if the Arab League wants to step in and do what should be done, my hat is off to them in making this tough moral and political decision.
