They're trying to build a radical Muslim state, so they need radical Muslims to support them. Exploding bombs is the best way to get the non-Muslims to turn against all Muslims, who become more likely to radicalize as a result. Moderate people are useless to ISIS and their kind.

At least, that's how I understand ISIS explains it themselves in their promotional material, haven't actually read those myself.

And it seems to work. I'm from Belgium and I can even see a moderate average guy like myself turning against Islam. Frightening really, how easy it is to manipulate people into in-group out-group thinking. All we need now is a charismatic leader for history to repeat itself.

We don't yet know who the perps are (feel free to correct me). My bets are also on Muslim crazies, but lets not forget Brevik.
