Show Notes

The U.S. determines by early 1945 that Japan will never surrender and will need to be subdued by force. Newly sworn-in President Truman must authorize an invasion of the Japanese home islands at a terrible cost to American lives. Emperor Hirohito hopes to avoid the destruction of his land and people, but his generals are agitating for war. Both men seek a way out, but only one can deploy the most terrible weapon the world has ever seen.
