Answer:
In the twentieth century, conflicts such as the two world wars and the Cold War occurred on a global scale.These global conflicts led to cultural or social changes during this period and marked social divisions that lasted for many years, affecting foreign relations on one side, and internal societal changes, on the other. The two world wars left an imprint of pain and suffering in the collective memory of Europe. Foreign relationships changed and the partition f power in the world changed too. Soviet leader Joseph Stalin opted to keep the occupied countries and instilled Communism. We are talking about East Germany, Romania, Albania, Hungary, Poland, and Czechoslovakia. The USSR supported the spread of Communism all over the world and the United States applied the policy of containment, trying to stop the spread of that political and economic ideology. Both countries supported their respective sides in the Korean War and the Vietnam War. They also competed in the arms race and years later, in the space race.These issues created too much tension and the world was on the brink of another war in the times of the Cuban missile crisis.
