Which global conflict from 1945 to 1991 involved an intense arms race and is associated with the term 'Iron Curtain'?

• A. World War II
• B. World War I
• C. Korean War
• D. Cold War

Answer: (D)

This item centers on the Cold War, a long period of geopolitical tension from roughly 1945 to 1991 between the United States and its allies and the Soviet Union and its allies. It was defined by an intense arms race, with both sides building up nuclear arsenals and delivery systems as a deterrent and bargaining tool, creating a pervasive sense of threat without full-scale direct conflict. The term Iron Curtain captures the ideological and physical division between Western Europe and Soviet-influenced Eastern Europe, signaling how sharply the world was split into opposing blocs. Those features—the sustained arms competition and the symbolic barrier between blocs—make this era the best fit, while the other options refer to different conflicts or earlier periods.
