  2. After Okinawa, a land invasion of Japan in next-Tokyo and other major cities being bombed • Decision needs to be made on how to end war against Japan

  5. Potsdam Declaration- President Truman warns Japan of “prompt and utter” destruction if no surrender (late July, 1945)

  8. Nagasaki- August 9, 1945 • ‘fat man’ dropped, killing 35,000 • Estimated 240,000 eventually die (total) due to initial bomb blast and after effects

  10. Hiroshima

  11. Nagasaki

  12. Nagasaki

  13. Why Hiroshima? • Hiroshima was chosen as the primary target since it had remained largely untouched by bombing raids, and the bomb's effects could be clearly measured. While President Truman had hoped for a purely military target, some advisers believed that bombing an urban area might break the fighting will of the Japanese people. Hiroshima was a major port and a military headquarters, and therefore a strategic target. Also, visual bombing, rather than radar, would be used so that photographs of the damage could be taken. Since Hiroshima had not been seriously harmed by bombing raids, these photographs could present a fairly clear picture of the bomb's damage.

  14. After effects • (scientists estimate only .1 percent of capabilities!!!) • Japan surrenders on August 14, 1945

  15. Hiroshima one year later
