Kristol nails it:
There is some chance, after all, that John Kerry will be president in four months. If so, what kind of situation will he have created for himself? France will smile on him, but provide no troops. Those allies that have provided troops, from Britain and Poland and Australia and Japan and elsewhere, will likely recall how Kerry sneered at them, calling them "the coerced and the bribed." The leader of the government in Iraq, upon whom the success of John Kerry's Iraq policy will depend, will have been weakened before his enemies and ours--and will also remember the insult. Is this really how Kerry wants to go down in history: Willing to say anything to try to get elected, no matter what the damage to the people of Iraq, to American interests, and even to himself?
As usual, read the whole thing.
