Couldn't have said it better myself

The Washington Monthly -- THE FOREIGN POLICY CHOICE:

"Bush has simply made too many mistakes, and he's made them because of a deeply ingrained tunnel vision combined with a disastrously poor decision-making process. Neither of these things is going to change, and at some point you have to face up to the fact that this means he's almost certain to continue making disastrous decisions throughout a second term.

Kerry will certainly make mistakes, and he will likely learn the limits of diplomacy as well, but the alternative is far worse. Bush, after all, neither admits nor learns from his mistakes. Kerry does."
