Explanation:

Former president James Polk was one of the main believers of the idea of Manifest Destiny. According to this idea, the United States had a political and divine right to extend from the Atlantic Ocean to the Pacific Ocean, in order to bring the virtues of the American civilization to as much territory as possible.

James Polk believed so firmly in this idea that he thought all means to realize it were valid. He actually provoked a war with Mexico that the US won, and that resulted in the cession of most of the American Southwest, which until then was part of Mexico, to the United States.
