Why did President Roosevelt sent troops to support Panamanian rebels in the fight against Columbia?

President Roosevelt sent troops to support Panamanian rebels in 1903 primarily to facilitate the construction of the Panama Canal, which was crucial for improving naval and commercial shipping routes. By supporting the rebellion against Colombia, Roosevelt aimed to ensure a favorable political environment for the canal's construction, as Colombia had previously rejected U.S. proposals. This intervention was also part of Roosevelt's broader strategy of asserting American influence in Latin America through the Roosevelt Corollary to the Monroe Doctrine. Ultimately, the U.S. support helped Panama gain independence, leading to the signing of the Hay-Bunau-Varilla Treaty, which granted the U.S. control over the canal zone.
