Explanation: Harry’s Truman’s decision to drop atomic bombs saved lives. Without them an invasion of the Japanese mainland would have happened called operation downfall. Bloody fighting had occurred through Island hopping, and got more bloody the closer they got to the mainland. The Japanese Army was trained that the worst a person could do in battle was to surrender. If operation downfall went ahead, WW2 wouldn’t have surpassed the total number of American deaths, having more than the civil war. Millions more would have died.
The Soviets on August 9th invaded Japenese held Manchuria. They in the end took half of Korea. The Soviets would likely invaded North Japan with no atomic bombs being used. This would likely split Japan into what Korea is like today. The North a communist regime, the south a world power with one of the biggest economies in the world. Korea would also fall under a full communist regime. Not only did the Atomic bombings save lives from an invasion, but it also prevented it from spreading communism to millions more people.
