It Makes a Difference to the Sheep

North Korea is not interested in talking about its nuclear weapons program(s) not even bilateral talks with the U.S. (according to Xinhua News):

The North Korean spokesman said his country is now unwilling to hold direct talks with Washington or join the six-party talks because of the "hostile" U.S. policy toward Pyongyang and its persistence in trying to topple the regime of North Korean leader Kim Jong Il, Xinhua reported.

"Because the United States insisted its hostile policy toward the DPRK and refused to co-exist with the DPRK and persisted to switch over the DPRK's regime, the DPRK has no justification to take bilateral talks by one-to-one on the nuclear issue of the Korean Peninsula with the United States now," Xinhua quoted the official as saying.

Pushing brinkmanship to the brink, or a sign that North Korea has crossed the nuclear Rubicon? Who knows?
