Well, how hard was it to subdue the airline crews/pilots.. take the plane and fly it into a building... yet it took them a good 3-5 years to get that plan of action to take place.
So it may be less of a question of how hard, and more a question of... when?
Sikboy, you honestly think it's hard to get a nuclear warhead? Russia was selling 'em like candy to the highest bidder not too long ago. If Al Qaeda still has a lotta cash, then what's stopping them from getting their hands on a small nuclear weapon? I'm not talking ICBM size, but still, could be fairly big.
How many mid east countries have nukes they didn't purchase off the black market anyway?
