I agree a nuclear detonation is the least likely type of terrorist attack, by far. But I would not be too surprised to see something along the lines of the Tokyo subway bio-attack some day. In terms of what the terrorists are actually capable of pulling off, a Mumbai type of attack is most likely.

But their ambition exceeds their current ability, so I think they will keep trying for bigger things, and they may get lucky again some day. While working at the WTC just after 9/11, I remember thinking that the terrorists got an A+ for persistence, since this was their second attack on the WTC, and wondering what they'd try next.
