Origins of the Cold War

From Alliance to Rivalry

The Cold War did not begin with a single event but emerged from the collapse of the wartime alliance between the United States and the Soviet Union. During World War II, the two powers were united by a common enemy — Nazi Germany. But their fundamental incompatibilities — capitalist democracy vs. communist authoritarianism — were merely papered over.

Key turning points in 1945-1947:

• Yalta and Potsdam Conferences (1945): Roosevelt, Churchill, and Stalin agreed on postwar arrangements, but disagreements over Poland, Germany's future, and the meaning of 'free elections' in Eastern Europe quickly surfaced.
• Soviet consolidation of Eastern Europe (1945-48): Stalin installed communist governments across Poland, Czechoslovakia, Hungary, Romania, and Bulgaria — what Churchill called the 'Iron Curtain' in his famous 1946 speech in Fulton, Missouri.
• The Long Telegram (1946): George Kennan's dispatch from Moscow argued that the Soviet Union was inherently expansionist and could only be checked through firm 'containment' — a concept that would define US strategy for four decades.

The Ideological Dimension

The Cold War was not just a geopolitical rivalry — it was a contest between two comprehensive visions of how society should be organized:

The US model: Liberal democracy, market capitalism, individual rights, and multilateral institutions (UN, Bretton Woods, NATO). In practice, the US frequently supported authoritarian regimes when it served anti-communist interests.

The Soviet model: Communist party rule, central planning, collective ownership, and international socialist solidarity. In practice, the USSR imposed its model on satellite states by force and brutally suppressed dissent.

Both superpowers claimed universal validity for their systems. Decolonizing nations in Asia, Africa, and Latin America became the battleground for this competition, with both sides offering military aid, economic support, and ideological patronage to win allies.
