Japan Doesn’t Surrender
• Fat Man dropped on Nagasaki on August 9, 1945
• Real Reason for dropping the atomic bombs may have something to do the Soviet Union
• Agreements made at the Yalta Conference• May 8, 1945 V-E Day• August 6, 1945 1st Bomb dropped• Why would the U.S. want to prevent Soviet
participation in the Pacific?• What could we have done instead of dropping
the bombs?
