Truman told Stalin about the atomic bomb at the Yalta Conference?

Actually, President Harry Truman did not inform Soviet leader Joseph Stalin about the atomic bomb during the Yalta Conference in February 1945. The topic of the bomb was discussed later, primarily during the Potsdam Conference in July 1945, after the successful test of the weapon. Truman aimed to use the knowledge of the bomb as a means of exerting pressure on the Soviet Union, particularly in negotiations regarding post-war Europe. The decision to withhold this information at Yalta was part of a broader strategy to maintain leverage over the Soviets.
