What meeting did US decide to drop bomb on japan?

The decision to drop atomic bombs on Japan was made during the Potsdam Conference, which took place from July 17 to August 2, 1945. Key Allied leaders, including U.S. President Harry S. Truman, British Prime Minister Winston Churchill, and Soviet Premier Joseph Stalin, discussed military strategies and post-war plans. Although the use of the atomic bomb was not the primary agenda of the conference, Truman informed his counterparts about the successful test of the bomb in New Mexico. The bombings of Hiroshima on August 6 and Nagasaki on August 9 were subsequently carried out to expedite Japan's surrender in World War II.
