Containment
At the end of world war 2, many countries in europe and asia destructed leaving the united states and the soviet union as the sole global superpowers.During WWII the usa and the ussr were allies, however their different ideologies cause a rift and severe tensions.The USSR under stalin forced communism on it people, leading to genocide.
