In Defense of Truman's Use of the Atomic Bomb

President Harry Truman’s use of the atomic bomb on Hiroshima and Nagasaki, Japan during the Second World War is the most controversial decision in history. While it was an undoubtedly difficult decision, it was indeed necessary in order to end this six-year war that had ravaged the world. While many critics argue that the bomb was used primarily as an act of vengeance toward Japan, simplifying such a crucial moment in human history downplays the very real risk invading Japan posed to the United States.

The tremendous cost of using this weapon was the lives of hundreds of thousands of innocent Japanese civilians from the immediate and long-term effects of bombs. Despite the moral arguments against this choice, this was the best one for the American cause. Truman’s obligation was first to the American people and as commander-in-chief, he made the decision he believed to best for his constituents.
