What this topic is asking
Topic 9.3 asks you to explain the Cold War: the ideological and geopolitical struggle between the United States and the Soviet Union, the division of Europe, and the crises and competition that defined the conflict without direct war between the superpowers. The College Board wants you to grasp both the nature and the impact of the Cold War.
What the Cold War was
The division of Europe
Containment, the arms race, and crises
The struggle was waged by every means short of direct war.
How the Cold War shaped Europe
Why it mattered
The Cold War is the central frame of Unit 9 and of the entire second half of the 20th century. It explains the division of Europe and Germany, the shape of postwar reconstruction and integration in the west (Topics 9.2 and 9.10), the dynamics of decolonization (Topic 9.9), and the eventual fall of communism (Topic 9.7) that ended the era. Understanding the Cold War, its ideological roots, its division of Europe, and why it stayed cold, is essential to making sense of the contemporary continent.

Q1. Why was the Cold War called "cold"? [Recall]
- Cue. Because the two superpowers never fought each other directly, the danger of nuclear war was too great, so they competed through proxies, crises, propaganda, and the arms race instead.
Q2. Explain how the Cold War divided Europe. [Short explanation]
- Cue. An iron curtain split the continent into a Western bloc aligned with the United States and a Soviet-controlled Eastern bloc of communist states, a division embodied in a divided Germany and Berlin and enforced by rival military alliances.

Evidence (2): the iron curtain and divided Germany; containment, NATO, and the Warsaw Pact; the arms race and Cold War crises.
