Why was the United States so interested in the security of Latin America?

The United States has historically been interested in the security of Latin America due to strategic, economic, and geopolitical reasons. The Monroe Doctrine of 1823 established a framework for limiting European influence in the region, which was seen as vital for U.S. national security. Additionally, the U.S. aimed to protect its trade interests and ensure stability in neighboring countries to prevent the spread of communism during the Cold War. This interest has often led to interventions and support for regimes that aligned with U.S. interests.
