"With the abandonment of its plutonium program, U.S. officials claimed North Korea began an enriched uranium program. Pakistan, through Pakistani nuclear scientist Dr. Abdul Qadeer Khan, supplied key technology and information to North Korea in exchange for missile technology around 1997, according to U.S. intelligence officials. Pakistan's President General Pervez Musharraf acknowledged in 2005 that Khan had provided centrifuges and their designs to North Korea." - Wikipedia// Obviously, North Korea already had knowledge of Uranium enrichment for over a decade. When did they actually start enrichment? Since the agreement with the US to freeze their Plutonium program happened on Oct 1994, they started their enrichment research as soon as they could, perhaps in 1997. We don't actually KNOW when the program started, but it could have taken them years to come to this point. If you are not a paranoid, why believe that the Korean program is in effect for ONE year only?
