Did you actually watch the video?
Hitchens does not predict that at all ….
ISIS are just a spin off group of the muslim brotherhood that the US funded to fight against Assad.
That's it.
they are the more extreme elements of the NATo backed Anti-ASSAD forces.
how do you think they got all those shiny new cars and weapons?
they were funneled to them through the US funding/arming of "moderate al qaeda"
They're not even that.
ISIS are merely a large, unemployed street gang that hasn't met any serious opposition yet; they are just cockroaches and will eventually be eradicated as such ...
