The manhattan project idea is a pretty good and novel one, but keep in mind if left to their own devices these people would be the next Hitler or Stalin, only this time with nuclear weapons; their idealogy does indeed call for them to conquer the world under an Islamic banner, and say we do leave... fundamentalists will still take over, they will still have money, they will still try to develop nukes...and eventually it would come to our shores anyway, only quite possibly worse than any other time in history...
Same old fascist assholes, different region, different excuse to try to take over the world
You know?
