War is one of the worst occupations men can engage in - though genocide and some large scale injustices are worse, and their prevention justifies war. There is no such thing as a pretty war. The decision to be in war entails, always, the decision to do things that would be totally unacceptable in any other context. For this reason, the decision must be made with care, including detailed planning, meticulous training, permanent self reflection even under fire, and calm examination of everything afterwords so that mistakes not be repeated. Israel is currently examining itself, in a public, communal discussion. I cannot think of any other society which does this in such a frank and open manner; certainly never any of our enemies, but not any of our friends, either. The decision of our critics to cast this in a very different light tells mostly who they are, not who we are.
