On August sixth, nineteen forty-five, the first atomic bomb fell on the city of Hiroshima. Three days later, a second A-bomb fell on the city of Nagasaki.

PRESIDENT TRUMAN: "Having found the atomic bomb, we have used it. We shall continue to use it until we completely destroy Japan’s power to make war. Only a Japanese surrender will stop us."

STEVE EMBER: President Truman.

PRESIDENT TRUMAN: "It is an awful responsibility which has come to us. We thank God that it has come to us, instead of to our enemy.”

STEVE EMBER: The Radiation Effects Research Foundation in Japan estimates that between one hundred fifty thousand and two hundred forty-six thousand people died within two to four months of the bombings.

The bombings left Japan's rulers with no choice. In less than one week, they surrendered.

PRESIDENT TRUMAN: "I received this afternoon a message from the Japanese government. I deem this reply a full acceptance of the Potsdam Declaration, which specifies the unconditional surrender of Japan. In the reply there is no qualification. Arrangements are now being made for the formal signing of the surrender terms at the earliest possible moment. General Douglas MacArthur has been appointed the supreme allied commander to receive the Japanese surrender."
