Every year in early August, there are gathering of people in major cities around the world to "protest" the use of atomic bomb by US against the Imperial Japan during WW2. What these mostly young, impressionable, misguided and naive souls fail to see is the atomic bomb save millions of not just American but also Japanese lives. President Truman's decision to use the bomb is correct and withstood the judgement of history.
Yes, 2 bombs killed hundred thousands in a few days,however, the firebombing of Tokyo killed eighty thousand in one night, and other cities has also been bombed for months, blockade is working, but the Joint Chiefs estimate the Japanese won't be completely subdue well into 1948 even if there are no major set back.
A number of years ago, one newspaper in UK reported a grade school student came home in tears, telling her grandfather, a RAF bomber crew in WW2, words to the effect of, history teacher said those fly bombing missions against Nazi Germany are nothing but murderer of innocent civilian.
In some academic circle, revising and twisting historical fact to generated publicity for oneself or advancing an agenda are rather common, without realize or care the damaged they've caused.
