1. The Decision to Use Atomic Bombs

In August 1945, Truman made the momentous decision to deploy atomic bombs on Hiroshima and Nagasaki, forever altering the landscape of global warfare. This act hastened the end of World War II but at a staggering human cost. The decision remains contentious, viewed by some as a necessary move to save lives by avoiding a prolonged conflict, while others criticize its ethical implications and the ushering in of the nuclear era. Truman’s choice set a precedent for nuclear deterrence, a delicate balance of power that defines international relations to this day.
