Roosevelt Corollary — Shift from Deterrence to Intervention

International Relations / U.S. Foreign Policy

In 1904, President Theodore Roosevelt expanded the Monroe Doctrine by issuing the Roosevelt Corollary. He asserted that the United States could intervene in Latin American countries to prevent instability, especially during debt disputes that might invite European involvement.

With this, the doctrine evolved from a protective warning against outside powers into a justification for proactive U.S. intervention across the region.
