That is how Islamic areas of the middle east and Asia have existed for centuries, long before we poked around.
In all seriousness if you want Islam to change, bar it's players from living one life there and another in the west or europe. Ban them all until they police their own. The people in power in Islam enjoy the good life when nobody is watching. Denying them travel, higher education, and bank accounts outside their own region will do a lot to cause change from within.
You should be careful about criticizing this around here...
I don't care if Islam changes or not, as long as we limit its impact on us. Even if you are correct that Islam is "perpetual war," it is complete BS to think that we will be at war until we eradicate a religion and its billion adherents. As soon as you acknowledge that the goal is something short of that, then we need to define the goal. What do you think it is?
