This fight has no good guys. It’s an Islamic civil war. I’m sure that whatever Obama does it will be the wrong thing to do.
There are 2-1/2 million Syrian Christians under Asaad's protection, who would be slaughtered if the Muslim Brotherhood and al Qaeda take over. That is reason enough for us to support the status quo.
Obama's loyalties lie elsewhere, however: with the Saudis and with the Sunnis of his youth. The Saudis have strategic reasons to get rid of Asaad, given the threat to their security from Shia Iran. The Saudis' tools of war are the militant Sunni groups: MB, AQ and Hamas. The Brotherhood is useful to them in Syria, but not in Egypt. The Saudis are calling the shots in both countries. Obama and the Saudis part company on Egypt. Obama is more of a philosophically radical Sunni supporter. The Saudis are realpolitik, posturing as Sunnis for Arab world consumption: see Ikhwan/Sabilla. On the topic of Syria, the two worlds align. I think that Syria's balance of power will shift to the Sunni militants over the next few months, just as Gaddafi went from the verge of crushing the opposition to his assassination.
Nowhere, in all of this, is any concern for the interests of the U.S., even though its military, and blood, is being used to serve the interests of others.
