Droping the atomic bomb on Japan still holds the question of whether it was necessary or unnecessary, but how could that be when the bomb helped America in so many ways. Yes, it was necessary! America had to end the war as fast as possible and the decision to drop the bomb increased that process. To invade a country like Japan would have cost hundreds of thousands of lives and it would have devastated the country, and the Japanese were not people to just surrender when in battle, they fought to the last life and were not above suicide tactics as demonstrated by the Kamakazi raids. As terrible as it was, dropping the bomb probably saved thousands of lives and saved the country from ruin. It was basically the best way to solve the problem other than any alterior motives.
