Asahi in Japanese tonight states that with the frozen (in principle) North Korean nuke program, the Yangbyon facility was stopped in it's tracks. If construction continued, it surmises, then N. Korea would have enough plutonium producing capability to manufacture nearly 50 nuclear weapons per year.
The question is, now, if that production was never shut down and was shifted to another location, just how much production capability do they have? Are these empty threats? It has been said in congressional committee that N. Korea is also suspected of illegal, underground importation of plutonium from Russia, and that it could have engaged in illegal export itself.
I.A.E.A. IN VIENNA JUST ISSUED AN IRATE STATEMENT THAT SUCH N.KOREA PRODUCTION is a violation of IAEA safety standards and they ask for immediate cessation. I would suspect they will demand free inspection. Japan said they will ask N. Korea to cease their nuke development at a meeting in Malaysia 29 Oct. with NKorean leaders.
