Selig Harrison, of the Washington-based Center for International Policy, said Pyongyang was ready to return to six-party talks, but that the opportunity to persuade it to dismantle its nuclear programs had been lost.
The best that the United States, Japan, Russia, South Korea and China could now hope for at talks that have been stalled since last June was a freeze of existing programs, and time was running short even for that, Harrison said. snip
He also urged the Bush administration to make that gesture to allow for negotiations on a nuclear freeze before North Korea reprocesses more spent fuel rods, the process of converting fuel extracted from nuclear reactors into material suitable for nuclear weapons or passes on its technology. snip
But Harrison also cautioned against the United States using economic sanctions against the North, saying leaders had warned they would retaliate militarily if the Washington attempted to enforce any sanctions with a naval blockade.

Reading between the lines here it appears the US knows NKorea is preparing to detonate a nuclear device very soon. Like within a week or two. I may be wrong? But I don't think so.
