all i could think of while watching sum of all fears was that this is going to happen. not all the silly US/Russia defcon3 stuff, but the stolen nuke detonated in an american city. they made it look more complicated than it would be, and they downplayed the effects of the blast, but i have no doubt that it will happen. it's just a matter of when and where. so, maybe it was a good movie, but i was completely unable to enjoy it.
