Best Answer: - The development of the atomic bomb. Stalin learned the U.S. had the bomb from his spies, before Truman officially informed him about it. That made him suspicious of Truman.
- In 1946, Winston Churchill came to U.S. and gave what has become known as the famous "Iron Curtain" speech. He acknowledged America had become a world power and stated Soviet aggression caused an "iron curtain " to descend across Europe. It caused tension and made the Soviets more suspicious the U.S. and Britain were teaming up against them.
- See below, there were many examples of hostile action by the Soviet Air Force against the U.S. airplanes between 1945 - 1949, and much longer, that caused tension, and actually I'm surprised those actions didn't start another war.

glory for their work in planning. For example, during the Yalta Conference, which was held in aRussian resort town in the Crimea from February 4-11, 1945. At the meeting, though, “The bigThree” each brought his own agenda that he wished would get negotiated at the conference.Churchill expressed his desire to keep his empire maintained as is, Stalin expressed his urgencyto capture more land and to strengthen conquests, while FDR expressed their need and want for Stalin to cooperate in the United Nations. Upon Stalin’s topic of gaining more opportunities, thequestion of Poland soon arose. Stalin went on to claim that given Poland, they would feel a senseof pride and honor and also claimed that obtaining a stronghold on Poland is merely a safety precaution for Russia and its people (DOC C). At the conference, Churchill and Roosevelt weremade clear that Stalin’s plans for Poland were nonnegotiable and were not about to change for anything. Thus, Churchill expressed the need of free elections in Poland to hold up the ideal of democracy. In order to keep the peace among “The Big Three”, Stalin reluctantly agreed to keepfree elections Poland, while deceiving Churchill and Roosevelt of the fact that he had recentlylaced a Communist puppet government in Poland. Unfortunately, Stalin was quick to go back onhis word and it became apparent that he had no intentions of keeping free elections on Poland. Itwould go on to be fifty years after the agreement at the Yalta Conference that P––oland wouldsee the light of free elections. The misunderstandings that took place at the Yalta Conference aswell as others, exploited the vague trust and loyalty “The Big Three” had for each other. In fact,the Americans had expressed their distrust of The Soviet Union at their outset to war, way beforethe Yalta Conference. Senator Truman, in 1941, expressed his and other American’s wish for The Soviet Union and Germany to kill each other off (DOC A). Thus, in essence, The SovietUnion was still not liked enough to be trusted, in fact the relationship they held with Britain andThe United States of America was solely on the idea that “the enemy of my enemy is my friend.”Therefore, the tensions that plagued American-soviet relations during interwar years rooted fromthe idea that: America, by way Sen. Truman’s statement, expressed a deep distrust of The SovietUnion, Stalin misunderstood the concept of a promise at the Yalta Conference and expressed his belief that America and Britain did not understand the deep fear that many Russians held at thetime of a German invasion .As a result, deep suspicions and mistrusting grew among “The BigThree”, but more so for the American-Soviet relations.
