Do you remember Harry Truman and FDR as butchers?
It is a shame nobody ever stood trial for the Dresden bombing (don't know how much personal responsibility FDR bore for that, however). I tend to judge the Hiroshima and Nagasaki bombings by a different standard, as they did bring a quick end to the war, and the alternative would have involved Allied troops invading the Home Islands while Japanese civilian militia tried to fight them with spears.
