Our President appears to have decided that it in his best interest to get Congressional approval for military action against the Assad regime in Syria. If it turns out to be a total screw-up, which appears to be increasingly likely if he goes ahead with it, it won't be only his fault. If Congress turns him down, as Parliament turned down David Cameron, he can breathe a sigh of relief and back down. The cowards in Congress will be responsible for their failure to avenge those dead children. Politically, it's the smartest thing he could have done.
The Syrian civil war, essentially, is the most recent outbreak of a regional conflict between Shi'a and Sunni Muslims that began back in the seventh century. We can't solve it, and the smartest thing to do is not try. It comes down to Iran (where the US is "the Great Satan") v. Saudi Arabia (the home of Al Qaeda.)
Furthermore, no multinational corporations seem very involved in Syria, so why should the Army of the Multinationals (ours) get involved? Let's wait for a real threat to the bankers, the arms merchants, the commodities traders, et al.
I'm kind of glad August is over.
