					Nuclear Weapons
          Manhattan Project
• Albert Einstein

• Fears about Germany’s
  Bomb
           Manhattan Project
• Groves and Oppenheimer + $2billion

• VE-Day Before
  Bomb Finished
 Reasons FOR Dropping the Bomb
           on Japan
• Japanese demonstrated they would fight until
  the last man (Okinawa, Tokyo Fire Bombing,
  Saipan)
• Can’t waste bomb over unpopulated area
  because only 2 available
• Invasion of Japan likely to lead to casualties on
  both sides greater than deaths at Hiroshima and
  Nagasaki
• Use of the bomb convinced the world of its
  horror and prevented future use
• Impressed the Soviet Union and halted the war
  quickly enough to save Japan from joint
  occupation
 Reasons AGAINST Dropping the
            Bomb
• Japan ready to quit anyway—60% of cities
  destroyed, Islands blockaded by US Navy
• US insistence on unconditional surrender
  prolonged war (Japanese wanted to keep
  emperor)
• Demonstration explosion would have brought
  peace without killing many
• Bomb only used to justify expense of program
• Cities bombed had limited military value
  (Hiroshima had 6 civilians for ever 1 soldier)
• Bomb only used to scare Soviet Union
• Even if 2nd bomb WAS necessary—US didn’t
  give enough time between bombs to for word to
  get out
