MEXICO CITY — Historians and political observers have criticized a recent White House statement commemorating the Mexican-American War, accusing the Trump administration of presenting a historically distorted account to support its foreign policy posture toward Latin America.

The unsigned statement, released Monday to mark the war’s anniversary, described the 1846–1848 conflict as a “legendary victory that secured the American Southwest, reasserted American sovereignty, and expanded the promise of American independence across our majestic continent.” It drew parallels between the period and the administration’s current policies, asserting that such actions would “ensure the Hemisphere remains safe.”

“Guided by our victory on the fields of Mexico 178 years ago, I have spared no effort in defending our southern border against invasion, upholding the rule of law, and protecting our homeland from forces of evil, violence, and destruction,” the statement said.

Critics noted that the post made no reference to the role of slavery in the conflict or to the broader consequences of the 19th-century doctrine of Manifest Destiny, which led to the displacement of hundreds of thousands of Native Americans.

Alexander Aviña, a professor of Latin American history at Arizona State University, said the statement downplays the violence involved in U.S. territorial expansion at a time when Washington has taken a more assertive approach to regional affairs.

“U.S. political leaders for generations have recognized this as a troubling chapter in history,” Aviña said. “This was a clear case of imperialism against a southern neighbor. The administration is framing it, inaccurately, as a defensive act.”

The remarks sparked swift reaction online. During a Tuesday morning briefing, Mexican President Claudia Sheinbaum responded with a quip, emphasizing her country’s sovereignty. Sheinbaum has sought to maintain a measured tone in dealings with the Trump administration, occasionally responding with sarcasm, including after Trump proposed renaming the Gulf of Mexico as the “Gulf of America.”

The Mexican-American War was rooted in longstanding border disputes and the U.S. annexation of Texas in 1845. In the years leading up to the conflict, American settlers moved into what was then Mexican territory. Mexico had outlawed slavery, and some U.S. abolitionists feared the expansion effort aimed in part to add new slave states.

Following a series of U.S. military victories, Mexico ceded more than 525,000 square miles of land to the United States. The territory included areas that now comprise Arizona, California, western Colorado, Nevada, New Mexico, Texas and Utah.

The war’s legacy has continued to shape relations between the two countries. Former U.S. President Ulysses S. Grant later described the conflict as “one of the most unjust ever waged by a stronger against a weaker nation.”

The episode also played a role in the origins of The Associated Press, which was founded by five New York newspapers that financed a pony express route to deliver news of the war more quickly than the U.S. Postal Service.

Albert Camarillo, a history professor at Stanford University, said the White House language reflects broader efforts by the administration to reshape how U.S. history is presented in federal institutions.

“It’s a distorted, ahistorical, imperialist version of the war,” Camarillo said, adding that the approach aligns with recent directives to revise exhibits at the Smithsonian Institution and to remove references on government websites that officials say “inappropriately disparage Americans past or living,” including materials addressing slavery, the destruction of Native American cultures and climate change.

Aviña said the statement underscores an effort to justify the administration’s “America First” policy across the region, regardless of historical consensus.

“This is about asserting a narrative that places U.S. actions in the Americas in a purely defensive light,” he said, “even when the historical record suggests otherwise.”
