The United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945. Scholars have extensively studied the effects of the bombings on the social and political character of subsequent world history and popular culture. There is still much debate concerning the ethical and legal justification for the bombings.
About Atomic bombings of Hiroshima and Nagasaki in brief

Nearly 99 percent of the defenders of Jima were killed; 94,000 of the defending troops in Okinawa were killed from April to June 1944. The ratio of Japanese to American casualties dropped from five to one in the Philippines to two to one by the end of the year. The Allied victory would come at an enormous cost, including the loss of 1.5 million military personnel and 1.6 million wounded in the Pacific War. The U.S. and Japanese forces fought fiercely, ensuring that the Allied victory came at a cost of $1.6 billion. The war ended on August 15, six days after the Soviet Union’s declaration of war and the bombing of Nagasaki. The Japan government signed the instrument of surrender on September 2, effectively ending the war and ending the Japanese involvement in the Second Sino-Japanese War. In 1945, the Allies’ Manhattan Project had produced two types of atomic bombs: \”Fat Man\”, a plutonium implosion-type nuclear weapon; and \”Little Boy\”, an enriched uranium gun-type fission weapon. In July 1945, a B-29 Enola Gay dropped a Little Boy on Hiroshima, an embarkation port and industrial center that was the site of a major military headquarters. Three days later, to take advantage of favorable weather, the B- 29 Bockscar dropped a Fat Man on Nagasaki, a majorMilitary port, one of Japan’s largest shipbuilding and repair centers, and an important producer of naval ordnance. In August 1945, America’s reserves of manpower were running out and there was consideration of drafting women.
