Paul Krugman expresses perfectly my biggest single concern about war with Iraq

though you don’t hear much about it in the U.S. media, a lack of faith in Mr. Bush’s staying power – a fear that he will wimp out in the aftermath of war, that he won’t do what is needed to rebuild Iraq – is a large factor in the growing rift between Europe and the United States.

The contrary danger is that he will do too much – embracing the Perle-Wolfowitz-Pipes doctrine of a war against the entire Arab world, driven ultimately by the concerns of the Likud Party, rather than by any realistic assessment of US or world interests (or for that matter of an enlightened view of Israel’s interests). But wimping out or losing interest seems more likely.
