Today marks the 75th anniversary of the bombing of Nagasaki on August 9, 1940.  The attack is reported here in that day’s issue of the Chicago Tribune.  If the Japanese needed further convincing to surrender, that day also brought news that the Soviets had declared war on Japan and were attacking Japanese forces in Manchuria.

The video below is a radio broadcast that day by President Truman promising that the bombings would continue until the Japanese surrendered.  The war would be over in a few days.
