Today I come to talk to you about a historical fact but first to ask you: What is an atomic bomb? How many atomic bombs do you think the United States sent to Japan during the second World War ? .Well, the United States carried out the atomic bombing of Hiroshima and Nagasaki, which left thousands dead, which showed how dangerous it can be to use an atomic bomb dropped on a city. Atomic bombs belonged to the Manhattan project during the second World War by the United States. That is why I want to tell you about the main events of the nuclear bombing of the cities of Hiroshima and Nagasaki, which were the declaration of war, the explosion of the atomic bombs and the surrender of the Japanese empire. Now that I've mentioned the Hiroshima and Nagasaki nuclear bomb events, I'll start by talking about the United States declaration of war on Japan, which began with Japan's attack on the United States naval base at Pearl Harbor, Hawaii on September 7. December 1941. The next day, December 8, 1941, the United States declares war on Japan, called the Pacific War. thus far we have examined the beginning of the conflict between the United States and Japan, later, on August 6, 1945, the United States bombed Japan with an atomic bomb called Little Boy, which exploded 600 meters above Hiroshima, leaving approximately 140,000 dead. However, Japan did not give in to the warnings, so the United States sent the second atomic bomb on August 9, 1945, called Fat Man, which exploded 549 meters above Nagasaki, leaving approximately 70,000 dead. Likewise, there were also survivors of the atomic explosions, who had burns and some people died after weeks or months due to the radioactive effects of the explosions. Finally, on August 15, 1945, Japan decides to surrender. And on September 2, 1945, the United States and other countries signed the Japanese capitulation, with the formal surrender of Japan, the second World War ended. To summarize, today I spoke for the first time about the main facts of the atomic bombings of Hiroshima and Nagasaki, first about the US declaration of war on Japan, second about the atomic explosions in the cities of Hiroshima and Nagasaki, and finally on the surrender of the Japanese empire. Likewise, this historical fact is considered as "the only military conflict in which nuclear weapons have been used in history that led to the end of the second World War". By which it has been shown that with the atomic explosions in the cities of Hiroshima and Nagasaki, that nuclear bombs are very dangerous, since they leave thousands of dead. Thank you very much.
