 there was agreement in the U.S. intelligence community that North Korea could build a "modest" bomb with a yield of between 6 and 10 kilotons, but disagreement between Defense Intelligence Agency, CIA and the United States State Department over whether it could deploy a miniaturized warhead on a missile.Rumours of an impending nuclear test circulated during 2005 and early 2006, though none came to immediate fruition.On October 3, 2006, however, North Korea claimed that it would soon conduct a nuclear test, and on October 9, 2006, the state claimed to have successfully conducted a test.
