A “Target Committee” was established to choose five cites to act as targets. They selected five cities that were deemed appropriate: Kokura, Hiroshima, Yokohama, Niigata and Kyoto. The criteria required for a city to be a considered target were that it must be larger than three miles in diameter, that the city was unlikely to be attacked by August 1945, and that the blast would cause sufficient damage to the Japanese Empire. US Secretary of War Henry L. Stimson requested that Kyoto be removed from the list of proposed targets, due to it being of too much spiritual value to the Japanese people. As per his request, Kyoto was removed and replaced with the important naval city of Nagasaki. Hiroshima, an industrial centre and site of a major military base, was selected to be the first city to be attacked, with Kokura and Nagasaki selected as alternative

    Leading up to the United States’ involvement in World War II, Japan exhibited aggressive imperialistic quests throughout Asia. After an attack on an American military base in Hawaii, the United States would enter combat in an attempt to curb the Japanese aggression. World War II consisted of battles mainly against Germany in Europe and Japan in the Pacific, and the Allies heavily relied on the United States to control the Pacific. American involvement in the Pacific eventually disabled Japanese aggression, as President Harry Truman called for the destruction of major Japanese cities via the atomic bomb. Despite an early advantage in the war, Japan was forced to surrender to the Americans, and as a result, the Allies proved victorious in the…

One option, “Operation Downfall,” was to be separated into two smaller operations: “Olympic” and “Coronet.”…

    On August 29, 1949, in Semipalatinsk, Kazakhstan, Russian physicists were busy at work, preparing for the detonation of their first atomic bomb: “First Lightening”. The nuclear blast of “First Lightening” was equal to the aftermath of “Trinity”, the first American detonation. Both bombs successfully incinerated caged animals and buildings constructed to stand against the blast and its deadly 20 kiloton explosion. Russian physicists were applauded for their work on the bomb and were honored with titles of “Heroes of Socialist Labor,” or the less reputable award, “The Order of Lenin.” If not for the successful detonation, these men would have been executed for failure of such a classified project.…

    The Target Committee believed that as well as being more effective against Japan, it would be beneficial in ‘making the initial use sufficiently spectacular for the importance of the weapon to be internationally recognized when publicity on it is released.” For this reason, Kyoto was considered as a better target because ‘Kyoto has the advantage of the people being more highly intelligent and hence better able to appreciate the significance of the weapon’ whereas Hiroshima was considered to be of value because the hills surrounding it would deflect the heat and shock waves back onto the city, maximising the damage. In addition, the Committee decided to delay any firebombing raids until the day after the atomic bombing so that the effects of the weapon could be properly…

    According to the book by John Hersey Hiroshima the city was an ideal target for American bombing as it was an important military centre of the region. The book states that the city “had been an inviting target – mainly because it had been one of the most important military-command and communications centers in Japan” (HERSEY, P.42). Besides the military importance, Hiroshima had a favorable geographical position which would help to harm the territory as much as it was possible so that to make the bombing impressive and to show off the military power of the United States of America. The places were chosen according to several criteria such as a number of closely-built houses and other buildings, how densely built-up the area was, military value, and the territory had to be…

    The Bombing of Hiroshima and Nagasaki: Abhorrent but Necessary On August 6, 1945, the city of Hiroshima, Japan went up in smoke when “Little Boy,” an atomic bomb developed in the secretive Manhattan Project, was dropped.
