Eh ... being in NYC I still feel (4 years later) that we've all got big red bull's-eyes painted on our backs. But I still feel that the likelihood of a "dirty bomb" attack here is much, much higher than the likelihood of a true thermonuclear explosion -- much easier (technically) than actually achieving fission and almost as good at stampeding the general public into hysteria, even though the actual body count would be much lower with a dirty bomb. Just my $0.02.
