Caribbean and Latin America, U. S. Military Involvement in the. Since the enunciation of the Monroe Doctrine (1823), U. S. policy towards the countries to the south has reflected the tensions between a self-interested appraisal of North American economic and military interests and an idealistic declaration of commitment to democracy. As the Monroe Doctrine indicates, the United States has viewed the New World as superior to the Old World, and the United States itself as the leader and protector of the Western Hemisphere. Yet the ideas of a common moral, political, and economic superiority in the New World and U. S. responsibility for the region have often produced impatience with the pace and direction of development in the Caribbean and Latin America. When impatience led to U. S. military intervention, the use of force was sometimes aimed at advancing the economic interests or national security of the United States and sometimes directed at keeping European influence out of the region.

As part of its expansionism, the United States government caused the Mexican War (1846-1848) and annexed the northern third of Mexico. In the middle of the nineteenth century, adventurers or "filibusters" like William Walker led privately armed groups into Nicaragua and other Central American and Caribbean countries with the hope of luring the United States government into annexing them. They were blocked, however, by local resistance as well as northern opposition to the expansion of the slave South before the Civil War.
