I was wondering how North Korea was getting the uranium to feed to their breeder reactor to get their weapons grade plutonium. I was pretty sure no one is selling it to them. The export regime is pretty good about not exporting to sketch countries. With their mines shut down and their reactors off line, they'd be limited to whatever waste they have now. It's a stop gap measure by far, but better than rising millions of South Korean lives as well as our own in fighting another war. Without material, a nation or group trying to make nukes is quite limited. It's a reason why both Obama and McCain were dead on the money when they proclaimed their mutual desire to secure all radioactive materials across the planet.
