What was Truman directive about where to use the bomb?

President Harry S. Truman's directive regarding the use of the atomic bomb was primarily focused on hastening the end of World War II by targeting Japan. He authorized its use against strategic military targets, with the goal of forcing Japan's unconditional surrender. The bomb was ultimately dropped on Hiroshima on August 6, 1945, followed by Nagasaki on August 9, 1945, leading to Japan's surrender shortly thereafter. Truman believed that using the bomb would save lives by avoiding a prolonged invasion of Japan.
