What was the significance of the Hiroshima and Nagasaki bombings in World War II?

The significance of the Hiroshima and Nagasaki bombings in World War II was that they marked the first and only use of atomic bombs in warfare. The bombings resulted in the immediate deaths of approximately 200,000 people, with many more suffering from long-term effects such as radiation sickness and cancer. The bombings also led to Japan's surrender, effectively ending World War II in the Pacific. The bombings raised ethical and moral questions about the use of nuclear weapons and initiated the nuclear arms race between the United States and the Soviet Union during the Cold War.
