Final answer:
The reason not associated with U.S. intervention in Central and South America during the Cold War is the fight for religious superiority between Catholics and Protestants. U.S. intervention was driven by anti-communism, extension of the Monroe Doctrine, and the Roosevelt Corollary.
Step-by-step explanation:
The main answer to the question regarding reasons for U.S. intervention in Central and South America during the Cold War era is 4) Catholics and Protestants fighting for religious superiority. This was not a motivation for U.S. intervention during that period. The U.S. interventions were mainly driven by concerns over the spread of communism, the extension of the Monroe Doctrine, the Roosevelt Corollary, and the desire to support capitalist interests and resist economic changes perceived as threats, such as land reforms or nationalization.Explanation: During the Cold War era, the U.S. was concerned about any indications of socialist-leaning leadership or communist tendencies in its hemisphere, which could impact American security interests and the dominance of capitalist ideology. This led to interventions justified under the Monroe Doctrine's claim of opposing European colonialism in the Americas, and later, under the Roosevelt Corollary, which expanded that doctrine to allow for U.S. intervention in cases of "wrongdoing" by Latin American countries. Religious conflicts were not a significant factor in U.S. policy decisions in the region. Conclusion: The United States intervened in Latin American affairs during the Cold War primarily to curb the spread of communism and protect its political and economic interests, rather than due to internal religious conflicts between Catholics and Protestants.
