This is what he said right before the U.S. invaded Iraq:
We are tempted to comment, in these last days before the war, on the U.N., and the French, and the Democrats. But the war itself will clarify who was right and who was wrong about weapons of mass destruction. It will reveal the aspirations of the people of Iraq, and expose the truth about Saddam's regime. History and reality are about to weigh in, and we are inclined simply to let them render their verdicts.
And this is what he said this morning:
We can try diplomacy. I'm not very hopeful about that. We have to be ready to use force." Kristol claimed the people of Iran would embrace "the right use of targeted military force."
He added that military force could "trigger changes in Iran," causing them to embrace regime change.
There are only two conclusions to be drawn here: 1. Kristol hasn't seen a television or a newspaper in a few years (if he is watching Fox News, or even CNN, this is kind of a viable theory), or 2. He has found a way to interpret what is going on in Iraq as a "success."
