Hot War-Cold War-Holocaust

Causes of Cold War :

In A Nutshell

The Cold War, a hostile rivalry between the United States and the Soviet Union, lasted from the late 1940s until the collapse of the Soviet Union in 1991. The war was "cold" only in that the United States and USSR never fought each other in a direct military confrontation, but both superpowers threatened each other with nuclear annihilation and participated frequently in "proxy wars" by supporting allied nations in numerous "hot" wars in places like Korean, Vietnam), and Angola. The Cold War defined both countries' foreign policies through the second half of the twentieth century, as Americans and Soviets competed for allies to maintain and widen their respective spheres of influence around the world. Each side viewed the Cold War as a battle between civilizations; in the worldwide clash between American capitalism and Soviet Communism, only one could prevail. For more than forty years, the Soviet-American conflict hung heavy over global affairs, shaping the world with massive military buildups, a never-ending nuclear arms race, intensive espionage, and fierce technological competition as each side tried to gain the upper hand in preparation for thethermonuclear "hot war" all humans feared would someday come.
