Section 13: The Second World War and the Americas (1933–1945)

By the early 1930s, fascist regimes were consolidating in Europe and Japan was expanding in Asia. U.S. policymakers feared that a resentful or divided Latin America would be vulnerable to Axis propaganda, trade penetration, and political influence.

Roosevelt's administration calculated that ending costly and resentment-generating military interventions would build goodwill that could later be drawn upon for wartime cooperation — base access, resource supply, and diplomatic alignment against the Axis.

While the Depression did strain federal finances, the primary driver was strategic, not budgetary. The policy was an active diplomatic investment, not merely a cost-cutting measure, as shown by the continued funding of Pan-American conferences.

The correct answer is that hemispheric solidarity against Axis influence was the strategic rationale. Non-intervention earned goodwill that the U.S. would convert into wartime cooperation — Brazil's bases at Recife and Natal being the clearest example.

The question asks for the primary reason the U.S. shifted from military intervention to diplomatic partnership in the 1930s, not merely a factor that made intervention inconvenient.

'Roosevelt wanted to reduce federal military spending' is a partial distractor — Depression-era finances were tight, but the Good Neighbor Policy involved active diplomatic spending (conferences, trade deals) and was explicitly tied to foreign-policy goals, not budget cuts.

'Latin American nations had collectively threatened to cut off all trade' is historically inaccurate — no such collective ultimatum occurred. Latin American states had little coordinated leverage to force this reversal unilaterally.

'The Monroe Doctrine had been formally repealed' is factually wrong — the Monroe Doctrine was not repealed; its interpretation was reframed through the Roosevelt Corollary's abandonment, but the doctrine itself remained a reference point in U.S. foreign policy.

The remaining option — that the U.S. sought hemispheric solidarity to block Axis penetration — correctly identifies the strategic motive behind the Good Neighbor Policy's launch, consistent with the broader context of rising fascism and Japanese expansion in the 1930s.

The Montevideo Conference (December 1933) produced the Convention on the Rights and Duties of States, which committed the U.S. to the principle of non-intervention in the internal and external affairs of other American states. This was the foundational legal act of the Good Neighbor Policy.

Each Pan-American Conference produced a distinct agreement: Montevideo (1933) = non-intervention; Buenos Aires (1936) = collective consultation; Lima (1938) = hemispheric defence reaffirmation; Havana (1940) = joint protection of European colonies. Mixing these up is the most common error.

The option about collective consultation belongs to Buenos Aires (1936). The option about jointly defending European colonies belongs to Havana (1940). The option about exclusive arms purchases is fictional. Only non-intervention belongs to Montevideo.

The correct answer is 'No state had the right to intervene in the internal or external affairs of another sovereign state,' which is the precise content of the 1933 convention signed by U.S. Secretary of State Cordell Hull.

The question tests precise knowledge of what the Montevideo Conference specifically agreed, distinguishing it from later Pan-American conferences that produced different commitments.

'States would consult collectively before military action' describes the Buenos Aires (1936) agreement — placing this at Montevideo confuses two separate conferences separated by three years and distinct circumstances.

'European colonies would be jointly defended' describes the Havana (1940) declaration, prompted by the fall of France — a full seven years after Montevideo and in a completely different wartime context.

'Latin American states were required to purchase military equipment exclusively from the United States' is entirely fictional — no such agreement was made at any Pan-American conference, and it would contradict the very spirit of non-coercion the Good Neighbor Policy promoted.

The remaining option — non-intervention in internal or external affairs — is the specific, documented commitment the U.S. made at Montevideo in December 1933, marking the diplomatic starting point of the Good Neighbor Policy.
