The United States dropped atomic bombs on Japan in 1945 to end World War II as quickly and with as few casualties as possible. That is the compelling and elegantly simple argument Robert Newman puts forward in his controversial new study of World War II's end, Truman and the Hiroshima Cult. Simply stated, Newman argues that Truman made a sensible military decision. As commander in chief, he was concerned with ending a devastating and costly war as quickly as possible and with saving millions of lives.

Yet, Newman goes further in his discussion, seeking the reasons why so much hostility has been generated by what happened in the skies over Hiroshima and Nagasaki in early August 1945. The source of discontent, he concludes, is a "cult" that has grown up in the United States since the 1960s. It was weaned on the disillusionment spawned by concerns about a military industrial complex, American duplicity and failure in the Vietnam War, and a mistrust of government following Watergate.

The cult has a shrine, a holy day, a distinctive rhetoric of victimization, various items of scripture and, in Japan, support from a powerful Marxist constituency.
