Two points to add to Jon’s post, directly below this one, on the possible Iraqi death toll:
One: when random Americans were polled a few months ago by the Associated Press, the median guess for the death toll was under ten thousand. So there’s a fair chance that however bad you may think Iraq is, you might want to multiply it by one hundred. We are talking about a possible literal megadeath. On our watch.
Two: predictably, the new estimate has already been dismissed out of hand by the Pentagon, as was last year’s Lancet study. But the Lancet study’s methodology is actually widely accepted; even John Zogby said it was “as good as it gets.” And the new poll, conducted by a respected firm whose clients include the Conservative Party, the Bank of Scotland, and Morgan Stanley — not exactly a bunch of raving lefties — is (as Jon notes) simply consistent with the Lancet study.
