Should the U.S. Build a Wall on Its Mexican Border?
China and Berlin have both had well-known walls. Now add the United States and Mexico to that list.

But while construction sits in limbo until Congress irons out the details, Americans have remained embroiled over the wall’s alleged benefits and detriments. Much like the land that comprises the U.S. and Mexico, the experts are divided.
