Final answer:
Yes, there was tension in the allied camp after Potsdam due to various factors such as dissatisfaction, distrust, and the atomic bomb. Truman was unhappy with the concessions made at the Yalta Conference, and there was a lack of trust between the allies regarding Soviet actions in Eastern Europe. Truman's hint about the atomic bomb heightened the tension.
Step-by-step explanation:
Yes, there was tension in the allied camp after Potsdam. The Potsdam Conference took place between July 17 and August 2, 1945, and it was attended by leaders from the United States, the Soviet Union, and the United Kingdom. The tension arose due to several factors. One of them was Truman's dissatisfaction with the concessions made by Roosevelt at the Yalta Conference, which allowed the Soviets to install a communist government in Poland. Truman was also concerned about Stalin's plans to demand large reparations from Germany. Additionally, there was distrust on both sides, as the Soviet Army still occupied much of Eastern Europe and Stalin had not fulfilled his promise of free elections in the region. Truman's hint that the U.S. had a powerful new weapon, the atomic bomb, increased the tension as well.
