I suspect that when the Islamic terrorists finally do use the a-bomb, it will be on Russia, maybe Moscow. There is so much unguarded plutonium in that area it's just a matter of time.
Must be a prima-donna complex: whatever's happening, has to be about them. WhoTF would need them, to attack or for any other purpose? The attacks and threats they have to face are of purely internal nature, like organized crime, restive ethnics etc.
While I agree that Moscow is a target. I suspect that it will be shipped to a port in a container. If they wish to do NY then they will have to control a fast ship and drive it close.
