Incidentally...
The issue here isn't clairvoyance, it's judgment and moral sense. Were you in favor of invading Iraq, or against it? The scoring system is binary, and I have to call it obfuscation to focus on the minutia of specific events.
I judged it wrong on multiple levels to invade Iraq. I was right. The score is 1-0.
The scoring system is not "binary," and never is, on issues of this kind. Both courses of action had consequences, and I seem to aggravate a lot of people by pointing that out now and then.
That the "minutia of specific events" makes you uncomfortable is not my problem.
