3. Cold War

At the end of World War II, the Soviet Union and the United States were vying for control of Europe. Despite the remaining Allies’ best efforts, the Soviets were gaining power and developing their own nuclear weapons, much like the ones the U.S. had used to decimate Nagasaki and Hiroshima and win the war. The mere presence of these weapons of mass destruction started a war of posturing and propaganda that lasted throughout most of the 20th Century.
