I strongly believe that as a sovereign nation the US should have full control over who can enter the country. This implies that border areas that are not legal entry points should have various forms of barriers with signs denoting the border and drones to detect violators. The structure and locations of these barriers, including some concrete walls, should be determined by experts in ICE who have the responsibility to bar illegal entry. It is not be necessary to construct a new Great Wall of China to accomplish this legitimate objective.
