The U.S.-Canada border was another concern by U.S. immigration authorities. This border is nearly 4,000 miles long. So, the northern and southern borders of the U.S., which are located adjacent to its only two neighbors, total nearly 6,000 miles in length. Constructing a physical barrier along both borders would be far too costly and difficult.
Many American politicians argued that walls or fences were a medieval solution outdated in our modern world. They suggested a technologically-sophisticated solution.
In September, 2006, the U.S. Department of Homeland Security (DHS) announced that it had contracted with The Boeing Company to build a “virtual fence” to guard the entire 6,000 miles of U.S. borders with Canada and Mexico. The system would consist mainly of video cameras, radar, electronic sensors with heat and motion detection, some fences and walls, and 1,800 towers. It would rely sparingly on aerial vehicles, such as drones, and be operated by the U.S. Customs and Border Patrol (CBP).
The U.S. federal government then contracted with Boeing to construct the “Secure Border Initiative,” shortened to SBInet. Boeing said it could include securing the U.S. coastlines, but cost much more. In late 2006, DHS admitted it could cost $30 billion.
That announcement put a big damper on the idea as Democrats took control of Congress in the late 2006 elections. Critics alleged that SBInet would not work. Senator Patrick Leahy (D-VT) called it a “cockamamie idea.” Actually, it would replace the America’s Shield Initiative project that was installed along the U.S.-Mexico border. This $500 million system consisting mostly of cameras and sensors had failed miserably. It was partly due to its technology not working properly. And the cost of the project originally was estimated at only $80 million. In early 2008, it was reported that illegal immigrants were easily getting through fences with torches, hacksaws, and ladders. In early 2011, the DHS admitted SBInet suffered too many problems and abandoned it.
In my home state of Arizona, Mitch Ellis is a manager for the Buenos Aires National Wildlife Refuge located along the Arizona-Mexico border. In 2006, Ellis put a different spin on the problem of illegal immigrants crossing from Mexico into Arizona. He pointed at a Mexican rancher’s steer that had crossed the border and was chewing grass on this U.S. refuge. Then Ellis quipped, “There’s an illegal immigrant.”
In 2014, the International Organisation of Migration estimated that 40,000 people had died due to attempted migration since the year 2000.
If the world eventually abolishes all conventional weapons and therefore relies only on primitive weapons, as I believe the Bible indicates, walls and fences for defensive purposes will surely make even more of a comeback than they have recently. For Bible texts indicating primitive weapons in the latter days, see especially Ezekiel 38-39.
