Donald Trump used a visual image for "seal off the border." He used a wall.

He isn't going to build a wall. He will not ask Congress for the funding.

He doesn't need to.

The border can be policed by satellites and a few thousand low-cost drones. The technology is cheap. It is available now.

These are cheap drones that carry no missiles. They only carry cameras. There can be night drones and day drones. They can observe what is going on for miles.

Put up 1,000 drones at all times, day and night. Aim their cameras 10 or 20 miles south of the border. Is there a truck coming north toward a desolate area? Meet it with troops.

There will be enough troops on the cheap fenced border to head off 80% of the trucks. If 80% of the trucks can't get their cargo through, the wholesale immigrant business is finished.

Post a thousand troops and drones at the high-crossing areas.

The strategy here is to eliminate the wholesale immigration business. Make the immigrants walk to the border in remote areas. This will drastically reduce the crossings. Move the immigrants from wholesale to retail.

MAKE A DEAL WITH THE COYOTES

Coyotes are the people who take money from desperate would-be illegal immigrants to take them across the border in trucks. They are middlemen.
