6. Arguments for dropping the bomb Military Pressures More deaths with an invasion Cost of the invasion Cost of the already- built bomb Use the bomb on military targets All is fair in war Secretary of War Henry Stimson

7. Arguments for dropping the bomb Send a message to the Soviets Tensions with the Soviet Union are growing as World War II is ending Dropping the bomb be a powerful statement of American strength and military dominance

8. Alternative demonstration of the bomb? Drop the bomb in a neutral location with international onlookers Good idea? Problems! Would the information be accurately reported to the empire? What if the bomb was a dud? No bombs to spare!

9. Unconditional surrender? Would the Japanese have surrender without us having to drop the bomb if we had eliminated the requirement of an unconditional surrender? Guarantee to allow the emperor to remain as emperor? Would this embolden the Japanese to fight for better terms? Concern over public opinion. Is this a sign of weakness?
