The Unclassified Report to Congress on the Acquisition of Technology Relating to Weapons of Mass Destruction and Advanced Conventional Munitions published by the CIA is written in a very interesting way.
The section on North Korea has absolutely no mention of the help provided by Pakistan. Now read B. Raman's article on the Pakistan North Korea nexus. Looks like B. Raman knows more than the folks at CIA. But tomorrow even if Musharraf opens his Nuclear Franchise Store in Langley,, right in front of CIA Headquarters, there will be no mention of this in the report. The spooks will still be wondering, "How the hell did these Koreans get this Nuclear Technology".
Also if you read the section on Libya, you will find that India is mentioned as one of the suppliers.
