She noted that the people she represents “do not want the United States to spend billions on another war that risks destabilizing the region, mass migration, and human rights abuses,” and argued that it is necessary “to protect our relationship with a close ally and avoid wasting taxpayer money on military force in Mexico.” “A war with Mexico, whether authorized or not, would endanger the lives of Americans and Mexicans and ruin America’s relationship with our most important trading partner,” Congresswoman Jacobs stated. “Bombing Mexico will not successfully solve the fentanyl crisis or the problems posed by the cartels; in fact, it could exacerbate both problems and provoke cartel retaliation against American citizens.

Unilateral military action against Mexico would certainly be a disaster,” Stanton added. He asserted that “America's security objectives must be achieved by working with Mexico, not by attacking it….”
