I think that's already happening. This conservative political/religous movement is an attempt to "protect our values". Unfortunately, it won't work. You can't fight religion with religion, or (Arab) conservatism with (American) conservatism. History shows it never works.

At best, one side will prevail and leave the losers plotting revenge for years, decades, centuries. If it comes to us or them, we'd be wise to remember that there are a LOT more of them than us.
