What James K Polk hoped to gain access to the pacific ocean through?

James K. Polk aimed to gain access to the Pacific Ocean primarily through the annexation of Texas and the acquisition of Oregon Territory. He believed that expanding U.S. territory westward would facilitate trade and settlement. Polk's administration focused on manifest destiny, the belief that the U.S. was destined to expand across the continent, which drove his aggressive policies toward both Mexico and Britain for territorial gains. Ultimately, this culminated in the Mexican-American War and the Oregon Treaty, securing the desired access to the Pacific.
