North Korea to declare, disable nuclear programs?

This sounds really good, but we need a little more detail before we celebrate V-NK day.

North Korea agreed Sunday to account for and disable its atomic programs by the end of the year, offering its first timeline for a process long sought by nuclear negotiators, the chief U.S. envoy said.

Kim Gye Gwan, head of the North Korean delegation, said separately his country's willingness to cooperate was clear—in return for "political and economic compensation"—but he mentioned no dates.

What is the difference between "disable" and "dismantle?" Does this include already enriched weapons material?

(Funny how much better this has gone since it got moved out of the White House and away from Condi Rice.)
