Which policy stated that the United States would oppose European involvement in the Western Hemisphere and would oppose attempts at colonization?

• A. Open Door Policy
• B. Truman Doctrine
• C. Monroe Doctrine
• D. Good Neighbor Policy

Answer: (C)

This question tests understanding of the Monroe Doctrine, a policy proclaimed in 1823 that the United States would oppose European involvement in the Western Hemisphere and would oppose attempts at colonization. It asserted that the Americas were off-limits to new European colonies and warned that European powers should not interfere in the affairs of independent nations in this region. In return, the United States would not meddle in European wars or politics, focusing instead on hemispheric affairs. The other options address different aims: the Open Door Policy concerned equal trading rights in China; the Truman Doctrine sought to contain communism after World War II; the Good Neighbor Policy aimed to improve relations with Latin America and reduce interference, but it does not explicitly state opposition to European colonization in the Americas the way the Monroe Doctrine does.
