In 1945, in an effort to end the war, America dropped two nuclear bombs on Japan. Specifically, Nagasaki and Hiroshima. The reason they dropped this bomb was to end World War II. The only other reason was to invade Japan which would have cause a higher total casualty rate. America and tried to make Japan to surrender through other methods that just didn't work so the two bombs were dropped. I think it was justifiable because Japan started it by attacking Pearl Harbour and because it was the better option besides invasion. What do you think? Discuss.
