During his presidency, Theodore Roosevelt made several interventions in Latin America. One of his most significant interventions was the construction of the Panama Canal. Roosevelt wanted to build the canal to connect the Atlantic and Pacific Oceans, which would make trade and transportation easier and faster. To get it done, Roosevelt supported a revolution in Panama, which was part of Colombia at the time. The revolution succeeded, and Panama became an independent country. The U.S. then signed a treaty with Panama to build the canal.
Roosevelt also implemented the Roosevelt Corollary to the Monroe Doctrine, which stated that the U.S. had the right to intervene in Latin American countries to protect U.S. interests. This doctrine was used to justify U.S. intervention in several countries in the region, including Cuba, the Dominican Republic, and Nicaragua. In Cuba, for example, the U.S. intervened to end the Spanish-American War and later occupied the country for several years to promote stability and protect U.S. interests.
Overall, Roosevelt used a combination of diplomacy, military force, and economic pressure to achieve his goals in Latin America. While his interventions were controversial and often criticized, they had a significant impact on the region and helped to shape U.S.-Latin American relations for decades to come.
