It seems more than coincidental that the Obama administration announced they would aid the Syrian rebels just one day after Bill Clinton said that Obama risked being thought of as a "wuss" if he sat by and did nothing.
Clinton is a master manipulator, and as such, understands that the best way to manipulate men is by telling them that their masculinity depends on doing whatever it is you want them to do. And Obama seems particularly vulnerable to that sort of suasion.
(The more manly response would actually have been to laugh at Clinton's comment and then ignore it.)
There is absolutely no upside to our getting involved in Syria. Assad has always been a repressive dictator, and more recently has been a murderous one; but he has also provided the kind of stability which suits our interests, The rebels are for the most part Muslim extremists who will merely install another theocracy. Their new government will undoubtedly be sympathetic to, and possibly even provide shelter for, al Qaeda.
The Arab Spring would have more aptly been termed the Sharia Spring. We have only just begun to reap its "benefits."
