  1. Harry S. Truman& The Atomic Bomb Power point created by Robert Martinez Primary Content Source: Speaking of History: Vol. II, by Laura Belmonte http://www.danzfamily.com/archives/blogphotos/06/393-tibbets-enola-gay.jpg

  2. In 1939, physicist Albert Einstein warned President Franklin Roosevelt that the Nazis were capable of producing a weapon that harnessed atomic energy. http://www.the-planets.com/star-biography/Albert-Einstein-Imagination.jpg

  3. In response, the Roosevelt administration funded small studies of the military potential of fission chain reactions. http://www.mphpa.org/classic/HF/Photos%20-%20Groups/group_20.jpg

  4. When the United States entered World War II, these efforts expanded into the Manhattan Project, a top-secret program employing more than 120,000 people. http://www.unit5.org/christjs/fermi-1.jpg

  5. American, British, and Canadian scientists (the Soviets excluded), collaborated in laboratories in Chicago, Oak Ridge, Tenn., and Los Alamos, New Mexico. http://www.losalamoshistory.org/mptest.jpg

  6. Their challenges included collecting enough fissionable material to produce a nuclear explosion and devising a weapon that could be dropped from an airplane. http://www.atomicarchive.com/History/trinity/jumbo.shtml

  7. On July 16, 1945, scientists at Los Alamos exploded the first atomic bomb (Trinity test.)

  8. At that time, the Allies had defeated Nazi Germany but were locked in fierce combat against Imperial Japan. http://www.nps.gov/archive/wapa/indepth/extContent/wapa/guides/offensive/images/fig20.jpg

  9. Earlier in the year, U.S. forces sustained heavy casualties in battles at Iwo Jima and Okinawa. http://www.ahoy.tk-jk.net/macslog/BloodyIwoJima.A36dayBattl.html

  11. Although the Japanese lost over 110,000 soldiers and 80,000 civilians in these clashes, they continued to fight. http://img25.echo.cx/img25/3126/esci2040rx.jpg

  12. U.S. military planners predicted huge losses if American forces invaded the Japanese home islands. http://www.archives.gov/research/african-americans/ww2-pictures/images/african-americans-wwii-101.jpg

  13. News of the atomic bomb’s successful test gave President Harry S. Truman an alternative. http://www.vw.vccs.edu/vwhansd/HIS122/Truman_Hiroshima.html

  14. On July 25, while he was attending the Potsdam Conference with Soviet and British prime ministers, Truman issued secret orders to use the bomb if the Japanese failed to surrender by August 3. http://www.flickr.com/photos/stefano_p/345154331/

  15. The Potsdam Declaration warned Japan that it faced “prompt and utter destruction” if it did not capitulate (end hostilities.) The Japanese rejected the ultimatum. Hideki Tojo http://www.dictatorofthemonth.com/Tojo/Apr2007TojoEN.htm

  16. In response, Truman ordered the military to use atomic weapons. http://www.lastplace.com/UFOArt/enola_gay.jpg

  17. On August 6, the B-29 Enola Gay dropped a uranium bomb on Hiroshima, instantly killing at least 70,000 people and leveling five square miles. http://www.webconverters.com/jec

  25. On August 14, Japan finally surrendered after receiving assurances that Emperor Hirohito could retain his throne. http://www.flickr.com/photos/msh-images/410781844/

  26. The decision to use the bomb remains hotly disputed. Critics offer several motives, including the desire to save American lives, anti-Japanese racism, and intimidation of the Soviet Union. http://www.serendipity.li/more/i4a.jpg

  27. Although we will never know the answer, nuclear weapons undoubtedly changed the course of modern history. http://www.edu.lahti.fi/~vvaljakk/WW%20II/truman.jpg

  28. “Let there be no mistake about it. I regarded the bomb as a military weapon and never had any doubt that it should be used.” - President Harry S. Truman http://www.medaloffreedom.com/HarryTrumanFreedomDay.jpg
