Advertising The US decision to drop atomic bombs on Hiroshima and Nagasaki in 1945 wa s meant to kick-start the Cold War rather than end the Second World War, according to two nuclear historians who say they have new evidence back ing the controversial theory. Causing a fission reaction in several kilograms of uranium and plutonium and killing over 200,000 people 60 years ago was done more to impress th e Soviet Union than to cow Japan, they say. And the US President who too k the decision, Harry Truman, was culpable, they add. "He knew he was beginning the process of annihilation of the species," sa ys Peter Kuznick, director of the Nuclear Studies Institute at American University in Washington DC, US. According to the official US version of history, an A-bomb was dropped on Hiroshima on 6 August 1945, and another on Nagasaki three days later, t o force Japan to surrender. The destruction was necessary to bring a rap id end to the war without the need for a costly US invasion. But this is disputed by Kuznick and Mark Selden, a historian from Cornell University in Ithaca, New York, US. They are presenting their evidence at a meeting in London on Thursday organised by Greenpeace and others to coincide with the 60^th anniversary of the bombings. Looking for peace New studies of the US, Japanese and Soviet diplomatic archives suggest th at Truman's main motive was to limit Soviet expansion in Asia, Kuznick c laims. Japan surrendered because the Soviet Union began an invasion a fe w days after the Hiroshima bombing, not because of the atomic bombs them selves, he says. According to an account by Walter Brown, assistant to then-US secretary o f state James Byrnes, Truman agreed at a meeting three days before the b omb was dropped on Hiroshima that Japan was "looking for peace". Truman was told by his army generals, Douglas Macarthur and Dwight Eisenhower, and his naval chief of staff, William Leahy, that there was no military need to use the bomb. "Impressing Russia was more important than ending the war in Japan," says Selden. Truman was also worried that he would be accused of wasting mon ey on the Manhattan Project to build the first nuclear bombs, if the bom b was not used, he adds. Kuznick and Selden's arguments, however, were dismissed as "discredited" by Lawrence Freedman, a war expert from King's College London, UK. He sa ys that Truman's decision to bomb Hiroshima was "understandable in the c ircumstances". Truman's main aim had been to end the war with Japan, Freedman says, but adds that, with the wisdom of hindsight, the bombing may not have been m ilitarily justified. Some people assumed that the US always had "a malic ious and nasty motive", he says, "but it ain't necessarily so."
