Death to both sides.
There are “good guys” in this fight but their fate will be the same as those in Libya and Egypt. The Mideast pattern is to throw the rational folks out there as cannon fodder and then come in with the Brotherhood or some such to mop up (including the “good guys”. So, regardless, this will not end well. See Iraq where the only question is whether the Iranians take over or split the country with al Qaeda.
