His insurance company took a $2.4 B hit on September 11th. Since investors need to understand a firm's risk and exposure, he has to consider these things from a business perspective, hence his company appears to be adding carve-outs for nuclear attack. I grew up during the cold war also (I was born just before the Cuban missile crisis). But MAD provided me with some peace-of-mind. For these radicals, there is no such deterrant. I find this to be a far more frightening and likely threat than the USSR or China. Apparently, the knowledge on how to build a bomb is no longer that difficult to attain, although the nuclear materials are. Does it not concern you that there are multiple reports of their attempts to acquire fissionable metarials, and appear to have been duped (hopefully) in all instances? They are not stupid, they will learn from their failures. I believe that over time and with money they will acquire these from somewhere. To ignore the threat does not help us.
