President Truman decided to use the atomic bomb against Japan?

Answer 1

So they would surrender, but they had already surrendered. My grandad told me they just wanted to test it. He should know he captured the last high ranked solider in the japs army. When I say captured he fell on to his own sword instead of being captured

Answer 2

Having found the [atomic] bomb we have used it. We have used it against those who attacked us without warning at Pearl Harbor, against those who have starved and beaten and executed American prisoners of war, against those who have abandoned all pretense of obeying international laws of warfare. We have used it in order to shorten the agony of war, in order to save the lives of thousands and thousands of young Americans.
