Eventually, the West will be forced to impose a quarantine on the islamic world.
That's assuming their world doesn't become our world in the next generation.
Personally I'd rather impose The Coulter Option on them.

I think the first Westerners to really go brutal in this war will be the Europeans. When their restive Muslim minorities go from the level of nuisance to existential threat, you'll see the Europeans revert to their historic practices of brutality and ethnic cleansing. The post WW2 period is the longest period of peace in Europe in centuries.
For example, The French suburbs that house the Muslim minority were designed with urban pacification in mind. They can be sealed off relatively easily, and their residents left to rot.
