From BRAD BLOG tipster, Jaime, as reported just now from Reuters:
SEOUL, South Korea - A large explosion occurred in the northern part of North Korea, sending a huge mushroom cloud into the air on an important anniversary of the communist regime, a South Korean news agency reported Sunday.
The Yonhap news agency, citing an unidentified source in Beijing, said the explosion happened Thursday in Yanggang province near the border with China. The explosion in Kim Hyong Jik county blasted a crater big enough to be noticed by a satellite, the source said...
So...since Bush doesn't do diplomacy and we can't invade N. Korea due to our lack of troop strength in the region (pulling our troops out of the region doesn't seem like a good idea does it Rummy?) and with our prior commitments in the totally necessary Iraq war...this doesn't bode well.
