Was America justified in dropping the atom bomb on Hiroshima in August 1945?

90,000 deaths almost instantaneously and estimates of additional deaths by the end of the year from injury, burns, and radiation poison 100,000. The Japanese still did not surrender, even after the Soviet Union entered the war against Japan on August 8 and on August 9 the A-bomb was dropped in Nagasaki. The following quotation is an excerpt from a public statement by President Truman given reasons for using the atomic bomb on Japan: “The world will note that the first atomic bomb was dropped on Hiroshima, a military base. That was because we wished in this first attack to avoid, insofar as possible, the killing of civilians. But that attack is only a warning of things to come. If Japan does not surrender, bombs will have to be dropped on her war industries and, unfortunately, thousands of civilian lives will be lost. Having found the bomb we have used it. We have used it against those who attacked us without warning at Pearl Harbor, against those who have starved and beaten and executed American prisoners of war, against those who have abandoned all pretense of obeying international laws of warfare. We have used it in order to shorten the agony of war, in order to save the lives of thousands and thousands of young Americans. We shall continue to use it until we completely destroy Japan's power to make war. Only a Japanese surrender will stop us.” After 14 years of the World War II, on August 10, 1945 Japan finally surrendered and ended the War.Many people will argue that the United States was justified in the dropping of the atom bomb. These people believe the dropping of the atomic bomb was necessary for Japan's surrender and the end of World War Two. It would bring the war in Asia to an end so American troops can go home along with troops from Europe. America had calculated that 500,000 to 1,000,000 American troops would be killed in order to mount a successful full scale invasion of Japan. Those figures do not include Japanese troops and civilians which could be killed during the fighting in Japan. Also, America wanted revenge from the Japanese for the surprise bombing at Pearl Harbor. The dropping of the A-bombs also started a new nuclear age and also it creates a threat of the dropping of an atomic bomb very real.Despite the justifications provided by people, who support the dropping of the atomic bomb, there are an equal number of reasons why other people believe it should never have happened. The destruction cause by the bomb is one major justification for why it should not have been used. Another justification to why the bomb should not have been dropped is that Japan was already about to surrender. One historian, Mark Weber, writes how unnecessary the bomb was, saying, “By any rational yardstick, they were not. Japan already had been defeated militarily by June 1945. Almost nothing was left of the once mighty Imperial Navy, and Japan's air force had been all but totally destroyed. Against only token opposition, American war planes ranged at will over the country, and US bombers rained down devastation on her cities, steadily reducing them to rubble.”  His point of view is like much the other people who believe that that Japan was ready to surrender with or without dropping the A-bomb. If Japan made the poor choice of staying in the war they would not be able to survive for long. As the Manhattan Project neared completion, some scientists and government officials suggested alternatives to using the atomic bomb. For example, an explicit warning to Japan by a demonstration of the bomb; agreeing to conditional surrender. That would be much better compared to having the bomb dropped and causing many civilian casualties or just have dropped it on Hiroshima as the one in Nagasaki would be unnecessary as Japan realize destruction that the atom bomb can cause.To conclude, the use of Atomic weapons in WWII was very unfortunate, but the events of dropping the Atomic bombs on Japan were necessary because it was the best way to end the world war. I think my opinion to the dropping of the Atomic bomb is successful. America was justified in dropping the atomic bomb. This is because America used the atom bomb to make Japan surrender and end the war, the surprise attack on pearl harbor it was also fair, the deaths from both countries if they had and invasion which would also include bombs though not as severe and they also gave Japan a chance to surrender before they dropped the bomb which makes it justified. Even though historians think that Japan would have surrendered without the atomic bomb, I think that Japan would follow the Japanese code of Bushido (the way of the warrior) and that they would never surrender. Therefore, to my opinion America was justified in dropping the atomic bombs on Hiroshima.
