Umm, let's see - this story first emerged back in 2001. Since then, we weren't nuked in 2002. We weren't nuked in 2003. We weren't nuked in 2004 (so far). Am I missing something???
REPETE AFTER ME--There are No suitcase Nukes! If they had one-- they would have used it in 2001-2002 or 2003. One Taxi cab rolling down Wall Street would have taken down the whole economic system. NO, these guys can talk up all sorts of things but they are all from whole cloth. Next it will be Photonic Cannons and giant killer robots. When they hit us it will be with something simple--not complex. If they had suitcase bombs why use airliners? This is just so much fear mongering. Next thing they will say that Osama has UFOs given to him my the lizard races of Venus.
