I think if people want to make the Korean War analogy, they should do it right. Bush sees the Korean War as a symbol of our commitment to fight aggression and lay the groundwork for development and, eventually, democracy, in South Korea. But we had achieved the liberation of South Korea by October 1950, mere months after the war began. We then made the disastrous decision to push into North Korea in an effort to topple the communist government there. That triggered Chinese intervention, and the war developed into a stalemate that dragged on for three more years. The eventual ceasefire returned things essentially to the status quo ante, an outcome we could have achieved at much lower cost had we not chosen to expand the war.

So, yes, the Korean War analogy is quite apt. Just not in the way Bush means it. The decision to invade Iraq in March 2003 looks a lot like the ultimately futile decision to invade North Korea in October 1950.

There's also the little matter of a US Army General whose names starts with an M. But that's another matter.
