Tyler Cowen takes a closer look at the recent "600,000 deaths in Iraq" claim. "We all know that the political world judges Iraq by the absolute badness of what is going on (which means Bush critics find a higher number to fit their priors), but that is an incorrect standard. We should judge the marginal product of U.S. action, relative to what else could have happened. In that latter and more accurate notion of a cost-benefit test, U.S. actions probably appear worst when deaths are rising over time, and hitting very high levels in the future."
