SEOUL, South Korea (AP) - Defense Secretary Robert Gates says the U.S. will never accept a nuclear North Korea.
He says the communist regime poses threats "even more lethal and destabilizing" than before. The Pentagon chief is in South Korea for annual defense ministers' talks.
Gates also says the North's nuclear program is a serious security challenge not only on the Korean peninsula, "but for the region as a whole."
Gates describes impoverished North Korea as a "serious proliferation threat." He says the regime seems to be willing to sell "everything" it makes.
In a separate interview in Seoul, the chief of the U.S. Pacific Command says North Korea "needs to be watched very closely." But Adm. Robert F. Willard also stressed diplomacy's role.
North Korea is believed to have enough weapons grade plutonium for at least a half-dozen bombs.
