Let's assume, arguendo, that one of these terror groups managed to detonate a nuke in a western city. It would inaugurate the Third World War, for sure. China, Russia, Western Europe, Australia, most of Central and South America, India, Canada and the USA would align in a completely mobilized campaign that would essentially destroy Islamic regimes worldwide and occupy whole nations for generations. If you think that, you're fooling yourself.
Sorry, but it's the truth.

I am easy to fool. What do you foresee as the US, regional or global response to such an event?
