1. During the Cold War, the Soviet Union detonated the largest nuclear weapon the world had ever seen. The Soviet Union detonated its first atomic bomb on August 29, 1949, at the Semipalatinsk Test Site in Kazakhstan. The event ended America's monopoly on atomic weaponry and launched the Cold War.
2. As World War II was ending, the Cold War began. This was to be a long lasting and continuing confrontation between the Soviet Union and the United States, lasting from 1945 to 1989. It was called the Cold War because neither the Soviet Union nor the United States officially declared war on each other.
3. Russian historians believe that Churchill and Truman are the ones responsible for starting the conflict aimed at destroying the US These differences caused the mounting tension between the Soviet Union and the west at the end of World War II.
4. The U.S. and the U.S.S.R. fought the Cold War for 45 years. It consisted of covert action, proxy wars and a nearly-complete polarization between the two sides among the rest of the world. In 1991, the U.S.S.R collapsed suddenly and completely, becoming a number of independent countries and the Russian Federation.
Hope this helps!
