I think that Truman recognized how the atomic bombings of Hiroshima and Nagasaki would have impacted the Japanese surrender. Truman almost anticipated. He recognized that a complete and total surrender on unconditional grounds was needed. The prevailing attitude at the time was that the Japanese use of kamikaze techniques demanded a total and complete surrender. Nothing less could be acceptable. Truman understood that in a little over a week after the bombing of Nagasaki that unconditional surrender from the Japanese was possible. At the same time, I think that he was able to grasp the implications of the bombings and its impact on civilian life. About three years after the bombings, Truman ordered an investigation on how the bombings impacted civilian life in both Hiroshima and Nagasaki. This represented how he recognized the full impact of the bombing and how it would eventually cause the unconditional surrender of the Japanese to the Americans. In the end, I think that Truman fully anticipated and understood that the unconditional surrender of the Japanese was going to be the result of the bombings at Hiroshima and Nagasaki.
