Madmen playing in the firehouse again

It's been confirmed that N. Korea has tested a nuclear weapon:

The U.S. Geological Survey, however, said it detected a 4.2-magnitude tremor at 10:35 p.m. EDT, which could mean the device was potentially deadlier than initially believed. Australia also said there was seismic confirmation that North Korea conducted a nuclear test.

"It was a success from their perspective in that they achieved a nuclear yield, though that is not very difficult," the official said. "It's within their technical capabilities."

And so, we go back on the merry-go-round. *sigh* I was really hoping that my child wouldn't have to grow up under the treat of a nuclear war...
