What Debris From North Korea's Rocket Launch Shows

Lasrick writes "David Wright of the Union of Concerned Scientists and the Bulletin of the Atomic Scientists analyzes the debris from North Korea's December 11th Unha-3 launch. From the article: 'According to press reports, traces on the inner walls of the tank show that the first-stage oxidizer is a form of nitric acid called "red-fuming nitric acid," which is the standard oxidizer used in Scud-type missiles. There had been some speculation that this stage might instead use a more advanced fuel with nitrogen tetroxide (NTO) as the oxidizer. Since the Nodong engines believed to power the first stage are scaled-up Scud engines, the use of RNFA is not a surprise. There have also been claims that the stage uses a more advanced fuel called UDMH, but it appears instead to be the kerosene-based fuel used in Scuds. In his recent RAND study, Markus Schiller noted that a test Iraq performed using UDMH in a Scud engine gave poor performance, and that burning UDMH gives a transparent flame. The North Korean video of the launch instead shows an orange flame characteristic of Scud fuels (Figure 3 is an image from 12:44 into the video). These findings confirm that the stage is still Scud-level technology.'"

    Then you must have never even heard of Liberia, DR Congo, Rwanda, and so on...

    Anyway, what's your justification for that extreme claim with religious undertones? Is it that you can't imagine worse horrors than what has been documented of NK? Believe me, worse horrors exist.

    Our people tend to have life expectancies in the very late 70s

    Only if you tend to be upper middle class to wealthy. Lifespans are actually shrinking for the poor.
