President Trump has been promising to build a southern border wallalong the US-Mexico border since he launched his presidential campaign in 2015. He argues it’s necessary to crack down on drugs, crime, and terrorism.
A 1,000-mile wall made of concrete or steel.
Nearly 2,000 miles long. More than 650 miles already has some sort of barrier (think: wire mesh, chain link). There are also areas where the natural terrain (like a river or desert) make crossing difficult.
This is what a section of the US-Mexico border fence looks like from Tijuana, Mexico. If you want even more visuals, here you go.
Some – like tall wire mesh fencing – are built with the goal of keeping people from crossing. Others – like shorter criss-crossing metal posts – are built to keep cars from crossing but not necessarily people. The Trump admin has eight prototypes for potential future kinds of barriers, including some made of concrete.
Some say no. For a few reasons:
Barriers aren’t stopping drugs. Most drugs come through legal ports of entry.
Barriers aren’t stopping undocumented immigrants from coming to and living in the US – people are still fleeing their home countries due to violence. And most undocumented immigrants are here on an here on an expired visa.
Barriers won’t address terrorist threats, because there is no evidence that terrorists are using the southern border to enter the US. Trump has argued that a wall is necessary for combatting terrorism.
Not necessarily. There’s evidence that barriers along areas like the one between Tijuana and San Diego have made crossing the border more difficult. Some people argue that in densely populated areas, barriers are important for making sure that border crossings don’t turn into a chaotic free-for-all. Others say it’s complicated – that different parts of the border need different solutions. EG: more rural parts don’t necessarily need a physical barrier but maybe could use drones and other tech to track crossings.
