Border Walls

Border walls are physical barriers erected by countries along their borders to control immigration, enhance security, and prevent illegal crossings. They can be made of various materials, such as concrete or steel, and vary in height and design. Proponents argue that these walls help secure national borders and reduce crime, while opponents claim they can be ineffective, costly, and may violate human rights. The debate surrounding border walls often reflects broader discussions about immigration policy, national security, and international relations. Examples include the U.S.-Mexico border wall and barriers built by other nations in similar contexts.
