>> Given the fact they have not successfully detonated a fission bomb in their first 3 tries, there are reasons to be dubious over this claim. They detonated the atomic bomb less than 50 miles from the Chinese border. A message?

Without a working fission bomb, no way they can detonate a fusion bomb. Just no way! Furthermore, so far no fall-out traces at all, that would be almost sensational if they managed to keep such a tight lid on. As far as I know, only the South Africa/Israel team managed that a long time ago and those guys were extremely sophisticated way over what can be expected from PRC. /Taro

From what I hear, it looks like NK didn't really test an H-bomb, but an enhanced fission bomb. Even this is said to have been a failure. Real H-bombs are very difficult to produce, requiring a lot of very high tech working together. India and Pakistan are doubted to have them. Foam plasma mechanism firing sequence. Warhead before firing; primary (fission bomb) at top, secondary (fusion fuel) at bottom, all suspended in polystyrene foam.High-explosive fires in primary, compressing plutonium core into supercriticality and beginning a fission reaction.Fission primary emits X-rays which are scattered along the inside of the casing, irradiating the polystyrene foam.Polystyrene foam becomes plasma, compressing secondary, and plutonium sparkplug begins to fission.Compressed and heated, lithium-6 deuteride fuel produces tritium and begins the fusion reaction. The neutron flux produced causes the U-238 tamper to fission. A fireball starts to form.
