The United States remains the only nation to have used nuclear weapons against another country. On the 6 August 1945, the United States Army Air Force (USAAF) detonated a uranium bomb over Hiroshima; 3 days later, on the 9 August 1945, the USAAF detonated a plutonium bomb over Nagasaki. These events were a display of power through an excessive use of force. Between 8 – 15% of those killed were military personnel. Between 85 – 92% killed were civilians; mere “collateral damage” in an act of war? No; it was an act of pure barbarism.
