Antagonism between East and West: The antagonism between the Soviet Union and the West that led to Churchill's speech had various origins...The United Kingdom, France, Japan, Canada, the United States and many other countries had backed the White Russians against the Bolsheviks during the 1918–1920 Russian Civil War, and the fact hadn't been forgotten by the Soviets. In the build up to World War II and in the face of the Western appeasement of Hitler the Soviets signed the Molotov-Ribbentrop Pact with Nazi Germany, one of the intentions being to divide the border states between them to form a buffer zone. Following the war Stalin was determined to acquire a similar buffer against Germany with pro-Soviet states on its border, leading to strained relations at the Yalta Conference (February 1945) and the subsequent Potsdam Conference (August 1945).

In the West, there was not only opposition to Soviet domination over the buffer states, but the fear grew that the Soviets were building an empire that might be a threat to them and their interests. And, in particular, Churchill was concerned that the United States might return to its pre-war isolationism, leaving the exhausted European states unable to resist Soviet demands. President Franklin D. Roosevelt had announced at Yalta that after the defeat of Germany, US forces would be withdrawn from Europe within two years (Antony Beevor Berlin: The Downfall 1945, p80).

Soviet intentions were plainly obvious long before Yalta or Tehran. ... As soon as the tide turned against Hitler, Stalin gave orders for Soviet agents to begin a campaign to secretly destroy non-communist, anti-Nazi partisans in eastern Europe that were actively engaged in fighting against Hitler’s forces. In 1944, Stalin’s armies stood aside while the citizens of Warsaw fought Hitler’s armies for two months and were massacred by the SS. The Soviets even refused to allow Allied planes to drop supplies to the resistance and shot at American planes that strayed into Soviet airspace ... Nor did Yalta lead to the peace and security that Roosevelt had imagined. Instead, it ushered in decades of tension and low-level conflict. Trading away the freedom of others proved no bargain. Because America received nothing in return, Yalta has to be recorded as one of the worst failures of “realist” foreign policy in history. [Source: http://hnn.us/roundup/entries/11904.html]

Answer 2

The Cold War, in my belief, started when the Karensky government fell to the Bolsheviks back in 1917. You can really see the tension build through the Red Scare that occurred throughout America. People were really paranoid, and the only time they would even acknowledge the USSR was when they needed an ally 16 years after the USSR was established. But the tension did become more blatantly obvious at the Yalta Conference.
