This is a 15-mark question requiring a sustained argument about whether fear of communism was the main factor shaping US foreign policy between 1945 and 1991.

What does the source show?

The source (a university textbook from 2001) argues that fear of communist expansion shaped "nearly every major American foreign policy decision" from 1947 onwards. It identifies key policies:

• The Truman Doctrine (1947) - committed the US to supporting nations resisting communist pressure, first in Greece and Turkey.
• The Marshall Plan (1948) - provided approximately $13 billion to rebuild Western Europe, partly to prevent communist parties from gaining support among impoverished populations.
• The Korean War (1950-1953) and Vietnam War (1955-1975) - American soldiers fought to stop the spread of communism.
• However, the source notes this "single-minded focus" sometimes led to support for authoritarian governments that opposed communism but denied basic freedoms to their own people.

Arguments that fear of communism was the main factor:

• Containment policy (articulated by George Kennan in 1947) became the framework for US foreign policy throughout the Cold War. The goal was to prevent the Soviet Union from expanding its sphere of influence.
• Key military and strategic decisions were driven by anti-communism: the Berlin Airlift (1948-1949), the creation of NATO (1949), intervention in Korea, the Cuban Missile Crisis (1962), the Vietnam War, and support for anti-communist forces in Afghanistan (1979-1989).
• The domino theory - the belief that if one country fell to communism, neighboring countries would follow - justified interventions across Asia, Latin America, and Africa.
• The nuclear arms race, including the development of hydrogen bombs and programs like the Strategic Defense Initiative (SDI, 1983), was driven by competition with the Soviet Union.
• CIA-backed coups and interventions in Guatemala (1954), Iran (1953), Chile (1973), and elsewhere were primarily motivated by anti-communism.

Arguments that other factors also shaped foreign policy:

• Economic interests were significant independently of communism. Access to oil in the Middle East, protection of American business investments abroad, and the promotion of free trade and open markets drove policies that would have been pursued regardless of the Soviet threat.
• The desire to maintain American global leadership and prestige motivated decisions that went beyond containing communism. The US sought to be the dominant world power, which required military bases, alliances, and influence in every region.
• The source itself acknowledges that the US supported authoritarian governments (such as Augusto Pinochet in Chile, the Shah of Iran, Ferdinand Marcos in the Philippines, and apartheid-era South Africa) as long as they were anti-communist. This suggests that strategic and economic calculations sometimes mattered more than ideology or democracy.
• Humanitarian concerns occasionally influenced policy, as in the intervention in Somalia (1992) and the response to the Balkan conflicts in the 1990s.
• After the Cold War ended (1989-1991), US foreign policy continued to be active globally - the Gulf War (1991), interventions in the Balkans, expansion of NATO eastward - suggesting that the desire for global leadership operated independently of the communist threat.

Reaching a balanced conclusion:

Fear of communism was the dominant framework for US foreign policy between 1945 and 1991, and it shaped more major decisions than any other single factor. However, it overlapped with and sometimes masked other motivations: economic interests, the pursuit of global power, domestic political pressures, and strategic calculations that would have existed without the Soviet threat. The source's observation about supporting authoritarian governments is particularly revealing - it shows that anti-communism sometimes served as a justification for policies that served economic or strategic interests rather than ideological ones. The most accurate conclusion is that fear of communism was the primary lens through which other interests were pursued, rather than the sole driver of every decision.

Exam technique: For 15-mark "how far" questions about causation, avoid simply listing factors. Explain how they interact with each other. Anti-communism and economic interests were often intertwined - the US opposed communist governments partly because they nationalized American business assets. Show this kind of analytical thinking rather than treating each factor as separate and unrelated. The strongest answers consider whether the stated factor was the cause or the justification for policies that had multiple motivations.
