I think I know where he is coming from. Since many muslims hate ISIS too, because they kill all Muslims who disagree or/and aren't Sunni he needs someone to blame for ISIS muslims killing other muslims.
Obviously - at least in his logic - jews must be responsible. Couldn't be possible muslims.
I have to add - US soldiers using pig blood bullets on civilians in Iraq. What? The last time I heard muslim extremist killing and blowing up civilians in Iraq on purpose. And lets talk about invasion - lets look at history books: Ever heard of islamic expansion? The thing ISIS tries to achieve - building a Caliphate like Mohammad did. Right now countries aren't invaded by the Western world to be modern.
Do you really think the West would care what islamic countries do as long as they don't kill people on a regular basis or they are funding terrorist groups? No one want's for example invade Turkey - you are paranoid.
