To answer the question of how the US forced Japan to surrender and bring an end to World War II, one of the key factors was the use of atomic bombs. The US dropped two atomic bombs, one on the city of Hiroshima on August 6, 1945, and the other on Nagasaki on August 9, 1945. These bombings caused immense devastation and loss of life. It is estimated that around 140,000 people died in Hiroshima and 70,000 in Nagasaki as a direct result of the atomic bombs.

However, it is important to note that the bombings alone did not immediately lead to Japan's surrender. Prior to the bombings, Japan was already facing significant military defeats and economic losses. The destruction caused by the atomic bombs further weakened the Japanese economy and military capabilities.

Additionally, the Soviet Union declared war on Japan on August 8, 1945, just after the first atomic bombing. The Soviet offensive in Manchuria further contributed to Japan's deteriorating position.

Following the two atomic bombings and the Soviet Union's entry into the war, Emperor Hirohito addressed the Japanese people on August 15, 1945, announcing Japan's surrender. This announcement led to the formal signing of the surrender document aboard the USS Missouri on September 2, 1945.

While the atomic bombings played a significant role in Japan's decision to surrender, it is important to recognize the broader context of the war and the multiple factors that led to Japan's ultimate surrender.
