Untrue.The attacks on Hiroshima and Nagasaki were of no direct military value whatsoever. They were attacks made by the military on civilians.
"By the end of the war, most of Japan's major cities had been destroyed by U.S. air attacks. Hiroshima was still intact. The reasons Hiroshima was chosen as the target for the A-bombing are assumed to be the following. The size and the shape of the city was suited to the destructive power of the A-bombs. Because Hiroshima had not been bombed, ascertaining the effects of the A-bomb would be relatively easy. Hiroshima had a high concentration of troops, military facilities and military factories that had not yet been subject to significant damage. "
"The first atomic bomb ever used against a civilian population was dropped on Hiroshima, Japan, on August 6, 1945. The city was chosen because it was a major port and a manufacturing center for aircraft and synthetic fuel. "
"Like Hiroshima, Nagasaki was chosen as a target because it was a major naval and shipbuilding center. In fact at the time of the bombing, the Nagasaki shipyards were the largest privately-owned shipyards in Japan."
You'll find your arguments work better if you try sticking to facts.
