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.'"

They now have an ICBM. Now they just need to miniaturize their nukes to fit on it. Next they will need submarines with nuclear missiles to protect them against a first strike. Then the only thing that will take them down will be internal strife. Considering that they are a batshit crazy country, China will prop them up as long as possible. So actually this hellhole might last pretty far into the future.

The secret to North Korea's longevity is that nobody wants to go in an clean up their mess. This is ten times more important when they have a reasonable delivery system for their nuclear weapons.

Is this comment some kind of a joke?

First of all, you can tell a LOT from this particular data point.

That aside, what are you insinuating? That a group widely and routinely chastised as espousing a "liberal" and/or "leftist" agenda by conservatives, opposed the now-cancelled US Reliable Replacement Warhead (RRW) program, and is opposed to nuclear weapons in general, is executing a propaganda campaign to make North Korea look more primitive than it really is when it comes to its rocket programs?

Are you serious?

After a veritable comedy of errors, North Korea finally has a successful launch, can't even get or keep the satellite launched from it into a stable orbit, and now an anti-nuclear advocacy group is really a secret US propaganda campaign to inappropriately embarrass the North Koreans, who are really more advanced in rocketry than all of their misadventures would indicate? The same North Koreans who just announced they have uncovered a unicorn lair?

Really? I mean...really?

Please â" I would love to hear how this is "propaganda", and how the DPRK is really a capable member of the space and nuclear clubs. To what possible end? Even IF it were true, why/how would that be a good thing?

Or is this one of those topsy-turvy bizarro-world lines of reasoning where anything and everything that is in ANY way opposed to anything related to any US or Western interest is automatically true and pure, but anything that originates from the US or West, in any way, shape, or form is always "propaganda"?

They "deserve the credit"? they've got half their country starving to death behind barbed wire, the other half starving in their crumbling capitol, they're spending all their money on BALLISTIC missle technology, and they... "deserve the credit". Well step forward and claim that prize, Best Korea.
