Congress voted and President Polk signed in favor of [this border](https://infographic.tv/wp-content/uploads/2019/05/Map-The-United-States-as-Polk-Would-Have-Wanted.jpg) after the Mexican-American War. If not for the overt treason of a single man, Nicolas Trist, whose writings reveal him to be a *literal* social justice warrior 150 years before the current ones. He deliberately disobeyed and negotiated for a border further north. He was fired and his replacement was shipped to Mexico City, but he rushed the signing of the Treaty of Guadalupe Hidalgo before he could arrive.
Polk should have had him arrested and executed (in a town square in Mexico City itself) and the treaty torn up and rewritten. But that wouldn’t have been “honorable” (to Mexico, or any foreign country) in that era.
