The Border Wall (United States)

The U.S.-Mexico border wall is a series of barriers intended to control illegal immigration and enhance border security along the nearly 2,000-mile boundary between the two countries. While construction and maintenance have been ongoing since the 1990s, the wall gained significant attention during the 2016 presidential campaign when then-candidate Donald Trump promised to extend it and increase funding. Proponents argue it helps reduce illegal crossings and drug trafficking, while critics contend it is costly, ineffective, and harmful to communities and wildlife. The wall remains a contentious topic in U.S. immigration policy discussions.
