The central message of the Monroe Doctrine was to warn against European expansion in the Americas. Established in 1823, the doctrine articulated a clear stance that the Western Hemisphere was no longer open to colonization or interference by European powers. This policy was rooted in the context of post-colonial America, where the newly independent nations were concerned about the potential resurgence of European colonial ambitions. The United States asserted that any attempt by a European nation to interfere in the affairs of countries in the Americas would be seen as a threat to U.S. peace and safety. This was significant because it marked an early assertion of American influence and a commitment to protect neighbors in the hemisphere against European dominance.

While the other options mention elements that do not align with the Monroe Doctrine's principles, the doctrine fundamentally emphasized a defensive posture regarding any foreign meddling in the Western Hemisphere, establishing a key part of U.S. foreign policy for years to come.
