Syria, let's divide it!

I'm confused.  Why are we involved in Syria's civil war?  It's hypocritical to claim any moral purpose of preventing Assad's government from massacring his own people.  We have no qualms about massacring people all over the the place and standing back or supporting other governments who do the same.  Are we taking sides in an Islamic power struggle?  Exactly how is the "Great Satan" going to come out of that looking good?  Is Israel driving the bus?  Jesus! How ironic.  Hey, I know. Let's create a new non sectarian state in the Middle East where everybody who has been forced out of their homeland can go.
