That's a ridiculous statement. IF Al-Qaeda nukes NY it would be irrational for the US to strike every Muslim country (or random ones) in retaliation. If Al-Qaeda were to nuke NY they'd have to be in NY with the nuke to do so, it couldn't be launched from overseas, that's highly unlikely. Al-Qaeda members are from various Arab-countries, yes, but you cannot hold their respective countries responsible for their actions. America has Arab allies, would they be nuked too?
