To commemorate the release of the movie "Oppenheimer" in Japan in 2024, we depicted the American physicist Robert Oppenheimer, known as the "father of the atomic bomb" for his successful development of the atomic bomb, as a tribute to him. I thought about Oppenheimer's glory and setbacks, his anguish and struggles. The following contains spoilers for the film Oppenheimer. The fact that many people died because of the technology he developed, and the impact of this technology, even today Japan is a colony of the United States (legally and formally, an independent country). Nevertheless, there was a reality that forced us to do so at that time. Even Einstein, who signed the document that the U.S. should proceed with nuclear development research, said, "There was no other solution. In the movie, there was a scene in which the researchers and the American people were overjoyed at the success of the atomic bombing and gave Oppenheimer a big round of applause. Some of them were so moved that they were crying. The colorful depiction of the mushroom cloud is a figurative expression from the American point of view. On the other hand, Oppenheimer felt guilty that he had killed so many Japanese. He was also a smart man who understood that he had increased the risk of nuclear weapons to the American people and to the rest of the world. The film ends with a conversation between Oppenheimer and Einstein. Oppenheimer "We thought that if a chain reaction started, it would destroy the whole world" Einstein "What about it" Oppenheimer "I am sure we did it" Although the possibility of a nuclear explosion causing a chain reaction in the atmosphere and destroying the whole world is "almost zero," the meaning of this conversation I think the meaning of this conversation is that Oppenheimer and others were anticipating that the success of the atomic bombings would lead to a fierce competition for nuclear development in the world, and that eventually such new weapons would be developed. In other words, the chain reaction referred to here is not only the nuclear explosion, but also the chain reaction that if the U.S. develops a new weapon, Russia will develop a new weapon that can match it, and so on. And there is a scene in the middle of the film where Oppenheimer is being severely interrogated by several people in a private room, and the image of the interrogators being exposed to the light of the atomic bomb, which I think represents a chain of hatred. Oppenheimer was moved to want to drop the atomic bomb on the people who were harshly interrogating him. I think this is such a scene. The line, "If you get hit, you hit back," is often said, but the chain of hatred, the chain of competition, and the chain of nuclear explosions all seem to express the essence of human nature. Oppenheimer said, "I am convinced that we have done it [the chain reaction and thus the destruction of the world]," even though the chain reaction of nuclear explosions that would destroy the entire world has not yet occurred. He probably believes that because the chain is so deeply connected to human nature, this vector cannot be stopped and will go as far as it will go. Hearing Oppenheimer's words, Einstein understood all that he meant and walked away with a stern look on his face. To paraphrase "I am convinced that we have destroyed the world" would be "We are the cause, and one day the world will surely be destroyed."
