That isn't the american border. That's obviously somewhere in Africa, and no one is watching that wall.
No one is proposing to build the wall and then walk away leaving it ungaurded. Yet, all the criticism of the wall rely on exactly that. That's how we know they are disengenuous. Even if the wall doesn't work, what's the harm in building it? $20 billion over 8 years is nothing compared to total government spending. In 8 years the federal government will spend about $32 trlllion dollars.
Build the ******* wall.
