it was necessary and justified for the United States to drop the atomic bombs on Japan because there had been reports about bombs already being created by Nazi Germany. The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki in August 1945, killing 210,000 people which impacted only children, women, and men. President Truman authorized the use of the atom bombs in an effort to bring about Japan’s surrender in the Second World War. In the days following the bombings Japan surrendered.The Manhattan Project was the US government program during World War II that developed and built these first atomic bombs.Detonation of these first nuclear bombs signaled arrival of a frightening new Atomic Age. The topic of the atomic bomb matters because it was the main point as to why we won the war. The Atomic bomb was a great idea because if we didn't invent/come up with the idea somebody else might have created it which would have lead to the death of us. One example of this is that “The Manhattan Project was the codename for the secret US government research and engineering project during the second world war that developed the world’s first nuclear weapons.” Another thing that was a surprise was that “President Franklin Roosevelt created a committee to look into the possibility of developing a nuclear weapon after he received a letter from Albert Einstein in October 1939. In his letter, Einstein warned the president that Nazi Germany was likely already at work on developing a nuclear weapon. By August 1942, the Manhattan Project was underway.” Even though we won the war there are still many bad reasons as to why the atomic bomb was a bad idea for example by detonating it killed many civilian men women and children which is illegal. The evidence for this is he League warned, “Any attack on legitimate military objectives must be carried out in such a way that civilian populations in the neighborhood are not bombed through negligence.” In other words, a special category of illegal weapons had been recognized, a category today called Weapons of Mass Destruction. This is why many people think the atomic bomb was not necessary. In the end the united states had the right to make the atomic bombs because many people see it as they get bombed or we get bombed so its either or. This topic is important to learn because it shows the type of decisions the government has to take whether they’re deadly or not. This relates to later events because we now know that nobody can make Weapons Of Mass Destruction. This is an actual issue that has come up now because a country that has already made bomb threats is North Korea.
