What most people in the West don't know is that these radical groups have killed more and done much more harm to Arabs and Muslims than they've done to the West. There was even a quote about them I read on FB that went "In order to get ISIS to fight with the Gazans against Zionist Occupation, you need to convince them that Israeli's are muslims"
The old timers here know my stance on dictators like Gedaffi, Bashar and the like, but I really do believe groups like ISIS are worst than these dictators, believe me if you read the Libya and Syria threads and see my posts there, that is a big statement coming from me. We have a group with a similar ideology to ISIS in Libya right now, if they gain control of Libya, they'll turn us to a more backward state than we are.
The problem in Iraq, is that Maliki has been so horrible to the Sunni's, he's marginalized them so much that he's pushed the Sunni tribes actually form a coalition with the ISIS, if it weren't for the Iraqi tribes, ISIS would not have made such progress militarily in Iraq IMO. I for one, think that just like in Libya when we allowed those extremists to fight with us in the revolution, the Iraqi's might regret colluding with them.
