I disagree with you. The US did not "STEAL" the land from Mexico. They paid American Dollars for it.Gadsden Purchase, 1853â€“1854
The Gadsden Purchase, or Treaty, was an agreement between the United States and Mexico, finalized in 1854, in which the United States agreed to pay Mexico $10 million for a 29,670 square mile portion of Mexico that later became part of Arizona and New Mexico. Gadsdenâ€™s Purchase provided the land necessary for a southern transcontinental railroad and attempted to resolve conflicts that lingered after theÂ Mexican-American War.
