North Korean leader ordered uranium bomb work "To tell the truth... (the late leader said) we are not waiting for the uranium-enriching technology to develop so it can be put to use by civilian industries" such as power generation, the paper quoted it as saying. "From a military point of view, it is a matter of course that we should use plutonium and highly-enriched uranium for atomic bombs," the document reportedly said, adding Kim Jong-Il gave subordinates "a concrete task to produce a massive amount of nuclear weapons." The Mainichi said the document was believed to be intended to make it clear to party cadres that new leader Kim Jong-Un had inherited his late father's strategy of attempting to develop nuclear weapons to protect his regime. The Tokyo Shimbun said it was the first time that explicit instructions from Kim Jong-Il on developing uranium bombs had come to light. It suggested there was little hope for any dramatic change in foreign policy under Kim Jong-Un for the time being, the paper added.
