This probably isn’t good…

Has North Korea tested a nuke?

This has little to do with Iraq, but there are various reports of a huge mushroom cloud following a tremendous explosion Thursday near North Korea’s border with China in Ryanggang province, a heavily militarized area. Thursday was the anniversary of the founding of the North Korean state, so the time and size of the cloud (two to 2.5-miles in diameter) suggest it might be a nuclear test, and there were worrying signs that the North was preparing to test a bomb.
Well, on the surface it looks like they have, but let’s wait to see what radiological and seismic tests indicate.
