The Cold War - U.S and Soviet Tension

Post-war Reconstruction Disagreement

Conference of the Big Three at Yalta, 1945, U.S. National Archives.

After the defeat of Germany in WWII, the allies differed on how to handle the reorganization in Europe.  Germany had attacked the Soviet Union so the Soviets wanted to punish them by taking control of the nations in Eastern Europe that Germany had defeated. The other allies, including the United States, wanted to help Europe rebuild.  There was already tension between the two countries because of the differing political views and the disagreement over Germany only added to it.

“I can deal with Stalin. He is honest, but smart as hell.”
~ President Harry Truman

“The United States should do whatever it is able to do to assist in the return of normal economic health in the world, without which there can be no political stability and no assured peace.”
~ George C. Marshall, Secretary of State

Truman Doctrine - Stop the Spread of Communism

Soon after the war the Soviet Union began installing Communist governments in the Eastern European nations it controlled.  The allies were concerned this was a start of a plan to spread communism throughout the world.  Rather than try to force the Soviets out of Eastern Europe, the U.S. decided to keep communism contained in the nations the Soviet Union already controlled.  President Truman announced the Truman Doctrine in 1947 that stated the United States would provide financial and military aid to any democratic nation facing communist threat.  The doctrine led to instances in which the U.S. and Soviet Union supported nations that engaged in military conflict.

“The main element of any United States policy toward the Soviet Union must be that of a long-term, patient but firm and vigilant containment of Russian expansive tendencies.”
~ "Mr. X", (George Kennan)

With differing political views and the disagreement about the aftermath of WWII, the Truman Doctrine started a period of tension and rivalry between the United States and the Soviet Union.   Neither side used military force against the other; instead they competed politically, militarily and scientifically.
