I think Obama is going to have to do something dramatic. He isn't afraid to give aid to insurgents in Syria, and he has to know by now that some or all of that will end up with the ISIS. My guess is that Obama will have to ask Hillary for advice, since it's probably going to be her show in 2016. And Bill and Hillary were never afraid to bomb anybody.
My ESP has never been particularly good, but I think they'll try to paint the ISIS as being a completely different enemy, and put troops on the ground again.
Onward and upward,
