-Build a series of equidistant military bases all the way around the lower edge of the United States, from one side of the country to the other. You wouldn't have to build the first one at the beginning of the border with Mexico; you could build it in South Carolina or Georgia and have the last one at or near the coast in Oregon.
-The primary functions of these bases would be for border security and also to facilitate emergency help for surrounding areas and places all over the country in the event of natural disasters.
-While the bases are being built, recruit people to work at them for the Army, Navy and Air Force.
-Border security presents a number of opportunities for problem-solving, and is a good career.
-The bases would create jobs and be good for local economies.
-They would be good career opportunities for women in the military, since they would be more interesting than desk jobs but less strenuous on a regular basis than combat. They would also be good training for people who want to have international, military careers.
-At the border, between the bases, build wall segments that are too high to scale and that are long enough that it would take a few hours to walk the length of a segment. The segments will cause predictable places where people will try to walk or drive into the United States, which will make it easier to apprehend them. The segments also won't be as ecologically disruptive as a continuous wall would be.
-Give the wall segments cameras and other sensors, and patrol the unwalled area between them with drones and whatever other technology is available. Some of the segments can also be storage, take-off and fueling stations for the drones, which means that there will be people around to operate them, to patrol, and to alert the nearest military base if there is an issue that requires additional help.
-Is there technology that could create electronic sensing capability between each wall segment?
