Good sign from North Korea

Last week, I mentioned skepticism about North Korea's progress in giving up its nuclear program. However, this weekend we had a very public and very positive sign, as they demolished the most visible symbol of that program:

SEOUL, South Korea (AP) — There hasn't yet been any official North Korean reaction to the destruction of the most visible symbol of its nuclear program, but a U.S. diplomat who witnessed it said Saturday that the big blast saddened government officials there.

A day after North Korea blew up the cooling tower at its Yongbyon reactor complex to demonstrate its commitment to abandoning nuclear weapons, the State Department's top Koreas expert said he believed the event was an emotional loss for the Stalinist state.

Still early, but a concrete step in the right direction.
