North Korea on Thursday announced for the first time that it has nuclear arms and rejected moves to restart disarmament talks anytime soon, saying it needs the weapons as protection against an increasingly hostile United States. The communist state's pronouncement dramatically raised the stakes in the two-year-old nuclear confrontation and posed a grave challenge to President Bush, who started his second term with a vow to end North Korea's nuclear program through six-nation talks. "We ... have manufactured nukes for self-defense to cope with the Bush administration's ever more undisguised policy to isolate and stifle the (North)," the North Korean Foreign Ministry said in a statement carried by the state-run Korean Central News Agency. The claim could not be independently verified. North Korea expelled the last U.N. nuclear monitors in late 2002 and has never tested a nuclear bomb, although international officials have long suspected it has one or two nuclear bombs and enough fuel for several more.
