Why America used atom bomb in World War 2?

Answer 1

Because Japan had attacked U.S. territory, destroyed U.S. Navy ships, killed U.S. military personnel, attempted to take over all of the Pacific Islands, and when the Japanese military was obviously loosing the war they refused to surrender. They wanted to keep their military together so that they could make another run on the Pacific, and they wanted the Emperor of Japan to remain in power. After the Japanese military had been driven back to Japan and Japan was completely surrounded, the Japanese people were starving and lacking in many basic necessities, but the Emperor refused to surrender and believed that further military action would result in a better outcome for Japan. They were continuing to fight in hopes of better "terms", but the U.S. and other Allies demanded that Japan surrender unconditionally after their agression in the Pacific. It was estimated that 750,000 U.S. and other Allied military personnel would die if Japan was invaded. And that was before more of the Japanese military was moved to the proposed landing area. Conventional bombing of Japan caused incredible fires and loss of life. The atomic bombs used on Japan were the only way to quickly end the war and save lives of Allied personnel. It was understood that if the public ever found out that the U.S. had such a weapon and didn't use it and subsequently 750,000 to perhaps over 1,000,000 U.S. soldiers died, the U.S. population would be outraged, and justifiably so. People today often think that they can see a better outcome to the war with Japan. Unfortunately there were no good options, just options that weren't as bad as others. It was a terrible time and the U.S. and the other Allies just wanted it to end so that life could get back to normal... whatever that is.

Answer 2

To end the war.

Answer

World War II was effectively over, with Japan as the only holdout. Japan had been asked to surrender several times and had refused. The nation had been blockaded so that no supplies were able to get in; the citizens were starving. The monarchy had convinced Japanese citizens that the Allies could not defeat Japan if its citizens worked to protect Japanese soil. Japanese citizens were "training" with pitchforks, rocks, swords and any firearms that they could find. Moreover, many Japanese soldiers were still hiding in the Pacific islands and preferred death to surrender.

When Japan had attacked the United States forces, the United States could not allow the action to go unchallenged. The options were either to reinforce the blockade or to use the newly available technology.

AnswerThe United States dropped the atomic bomb to defeat the Japanese and to end World War II. There was no way that the Japanese were going to run out of soldiers before the United States did. Eventually, the Japanese would attack, a second time, United States soil and would likely be successful. The United States believed that dropping the atomic bomb would send a clear message to Japan. AnswerThe Soviets

It is not true that the United States dropped the bomb to end the war by forcing Japan to surrender. However, there are at least two reasons, which have been overlooked, for dropping the atomic bomb.

The first reason is that the bomb was an attempt to stop the spread of communism throughout Asia. The first atomic bomb was dropped on August 7, 1945. Two days later, the Soviet Union joined the war against Japan, earlier then expected. On the following day, the second bomb was dropped. Is there a correlation? I believe so. If the Soviet Union had been allowed to re-enter Japan after losing to the country in the Russo-Japan war, it wouldn't stop at defeating the Japanese; it would go for total conquest.

The second reason for dropping the bomb was that it demonstrated to the Soviet Union the destructive power that the United States had created and was willing to use.

Answer 3

American didn't 'use' the atomic bomb in the '50's in the sense that they put it to the intended use, dropping it on an enemy. They set off a number of them in various tests. They also became a threat to other countries and were a point in negotiations.

Answer 4

The Japanese refused to surrender, (because it was against their Samurai code to surrender), and it was either drop two atomic bombs and end the war, or invade Japan and lose millions of people in the battle. Dropping two atomic bombs saved far more lives than they killed. More people died when Tokyo or Dresden were burned to the ground than died in the atomic bombing of Hiroshima or Nagasaki. The bombs were dropped, the Japanese surrendered, the war came to an end. Countless people who would have died in an unnecessary invasion lived.

Answer 5

President Truman stated that he needed to end the war and to collapse Japan's means to make war ever again.
