What a smorgasbord of "news" today. Which way to turn?

At NYT (italics mine):

"United States intelligence analysts have determined that the strength of the weapon tested by North Korea was less than one kiloton, extremely small for a nuclear explosion, one official said today.

'We have assessed that the explosion in North Korea was a sub-kiloton explosion,' said the intelligence official, speaking on condition of anonymity because of the sensitivity of the issue. He added, 'We don’t know, in fact, whether it was a nuclear explosion.'”

"There was widespread agreement that there had been some sort of seismic event in North Korea — The United States Geological Survey said it had detected a tremor of 4.2 magnitude. But monitoring agencies disagreed in their estimates of the force of the blast, raising some question about exactly what the North Koreans had done."

"President Bush denounced North Korea’s announcement as a 'provocative act.'”

"...he said that 'such a claim itself constitutes a threat to international peace and security.'”

"...Bush said the move requires an 'immediate response.'”

On MSNBC, this 0.5 kiloton "nuclear" test is at the "theoretical low end" of possible designs. But, "we should be scared." Big surprise.
