What do we know? 1) The North Koreans did receive Chinese and Soviet/Russian nuclear help when North Korea was still a NPT signatory. All such co-operation stopped once North Korea withdrew from the NPT. 2) We do know that the AQ Khan sold the November Kilos the same package he sold the Lybians which included the blueprints for a CHIC-4 warhead. 3) We have discovered more advanced versions of the CHIC-4 warhead blueprints in Geneva by AQ Khan. 4) All of AQ Khan's work was HEU. 5) The 1st November Kilo nuke test was less than a kiloton and noble gases were detected, indicating that it was a Pu device. AQ Khan's packages were all HEU. 6) The Intelligence Community deduced that the November Kilos went for a small warhead design right off the bat and as a result, the compression explosives were not properly placed nor designed, blowing the fissible materials faster than they could be compressed into a critical mass. 7) The failed warhead was designed to fit on top of a NADONG missile but no RV has been spotted. 8) The 2nd nuke test was calculated between 1.2 to 8 kts with the intelligence community going for the lower end calculations. However, no noble gases have been detected and there are strong suspicions the test may have been faked. 9) Chinese scientists, at least, think the tests have been faked, citing just how difficult it was to hide noble gases from a nuke test. 10) Majority scientific opinion is that the test was real but based more on opinion than gathered facts.
