Terrorist groups do have great access to nuclear material, however. Iraq had many tons of nuclear material sitting around. There's masses of nuclear material sitting around Russia, it's all over the place. Terrorists take it, and strap it to a conventional bomb, making a dirty nuclear bomb, as they are called. Not as bad as a Nuclear Warhead, but nasty stuff.
If we aren't in WWIII now... I'd say we just have to watch hammas, the militant radical muslim group that just was voted in as the leadership of Palastine. Many people say that Israel/Palastine will get us into WWIII.
(although, historically, it's more like WWVII or so)
