N. Korean Nuke

So it was a flub, probably due to pre-detonation. Nukes are really not that easy to build. But today we learn that the N. Koreans used plutonium (because uranium isotopes are so hard to purify) to make the nuke they exploaded. The plutonium was produced either during Bush I or the Bush II administration.

As president, Mr. Clinton negotiated a deal that froze the production and weaponization of North Korea’s plutonium, but intelligence agencies later determined that North Korea began its secret uranium program under his watch. The plutonium that North Korea exploded was produced, according to intelligence estimates, either during the administration of the first President Bush or after 2003, when the North Koreans threw out international inspectors and began reprocessing spent nuclear fuel the inspectors had kept under seal.
