Walter Nugent believes the Mexican War was indeed an exercise of American imperialism. Citing philosopher-historian Isaiah Berlin’s terminology, Nugent refers to then U.S. president James K.

His plan was to gain the territory from Mexico via trade and purchase. Mexico had incurred debt from U.S. citizens but did not have the money to pay it back. In exchange for the land, Mexico would be financially compensated on top of having its debt relieved (285).

The warnings from Mexico were met with American show of force as U.S. army troops were sent into Texas and the navy moved into the Gulf; Polk actually thought these actions would deter a Mexican attack
