The scientists who circulated petitions, particularly the Franck Report of June 1945, expressed concerns about the use of atomic bombs. One of the significant outcomes they proposed was that the United States should demonstrate the destructive power of the atomic bomb to Japanese leaders before deploying it in warfare. They suggested a demonstration in an unpopulated area to show the devastating impact of the weapon and give Japan an opportunity to surrender.
However, this proposal was not followed. Instead, the United States dropped atomic bombs on the cities of Hiroshima and Nagasaki in August 1945, leading to Japan's surrender. The actual events did not align closely with the scientists' recommendation for a demonstration, and the bombings remain a topic of historical debate
