Let’s see....Egypt has a border wall, Saudi Arabia has a border wall....apparently the 7th century is one step ahead of Congress in some areas.
Speaking with a Latino friend who btw votes Republican, he grew up in El Paso. He doesn’t favor a border “wall.” There is already a wall, with doors cut in it for passage. He remembers being a little boy and going from El Paso to Mexico to spend the night with his buds.
He’d prefer we spend our $ on an alternative approach...infrared, satellite, etc.
