I watched this documentary airing on Discovery Times yesterday. Quite scary. Traces how North Korea got their weapons and Iran got centrifuge designs.

Also looks at how Saudi Arabia could have potentially received nuclear designs, and how some top nuclear scientists even have links with al qaida (one of them is shown in a picture with osama bin laden).

I do not want to start a flame war. A copy of this documentary is on youtube.com

It is quite scary, and shows just how close we are to a world of nuclear chaos.
