Nuclear Tension Builds

President Bush said the United States would not tolerate a nuclear North Korea, and North Korea went nuclear. After it tested an atomic device last week, Washington said no more, and now North Korea is believed very likely to be preparing a second test, soon.

The Security Council has spoken. Sanctions have been announced. But the North Korean nuclear threat remains very much unresolved.

Now, Condoleezza Rice is on the road, in Tokyo, and headed for Seoul and Beijing. But it is not clear that Seoul and Beijing share Washington's fervor. And Pyongyang is talking war.

Hear about the unresolved North Korean nuclear crisis.
