This is, nonetheless, an important book, as it points out that Americans have made a moral choice to prioritize humane war, not a peaceful globe. Moyn hopes that pondering this choice might help the United States avoid mistakes in the future. The end of the draft, the all-volunteer armed forces and weapons such as drones have made war something that affects few Americans. Only occasionally, as with the recent U.S. drone strike in Afghanistan that killed 10 innocent civilians, are we reminded of the brutality that Tolstoy thought people should never forget. That prompts the question of whether Americans today even have the capacity for such national introspection — and if they do, whether it is too late for it to make a difference.
