Nuke Fraud?

North Korea’s Possibly Itty-Bitty Nuke (Updated) | Danger Room | Wired.com: "Fellow WIRED contributing editor Patrick DiJusto reminds us that “the explosive equivalent of a four kilotons nuke can and has been replicated using conventional explosives before, such as in operation Minor Scale. That generated 4.8 kilotons from ANFO (ammonium nitrate and fuel oil). “Are the North Koreans crazy enough to gather 4000 tons of ANFO in one place and set it off? We are led to think they are.”

Meanwhile, MIT’s Geoffrey Forden wonders whether the Nork nuke was a 20 kiloton designed that failed — or a successful, itty-bitty nuke that worked as planned."
