"The Chairman [sic] of the Joint Chiefs of Staff Admiral William D. Healy agreed [with the U.S. Strategic Bombing Survey] 'the use of this barbarous weapon at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender." (David Swanson's blog/War is a Crime.org, "Harry Truman and Memory if Mass Murder") It was rather the first blow in the "cold war" against the Soviet Union. On August 6, 1945 (& again on August 9th) we became the first & still the only nation savage enough to drop a nuclear bomb on two cities full of people.
One other thought on this 68th anniversary of one of the world's most horrific acts, the victims were people of color. Would we have dropped these bombs on German or Italian cities? I do not believe we would have,
War is horrendous under any circumstance. We must find another way to interact with each other, if the human race is to survive.
