On the North Korea nuclear test, there's not a whole lot to say. Expect the usual suspects to rattle their sabers, but the truth is, sabers are relatively useless when their target has atomic technology. Obviously, Bush's strategy on North Korea was a total failure, just as it has been on Iran, just as it has been on Iraq. Of the three Axis of Evil countries, 1) is now a killing ground for our troops and a potential proxy state for 2) who elected a wildly-anti-American president and is playing brinksmanship en route to enrichment while 3) has just gone nuclear. Some strategy. The question now is how we handle a nuclear North Korea and whether the Bush administration will listen to their inner realists and realize that they can't do anything but seek an accommodation.
