President Trump is right when he argues that drones and technology are not sufficient to stop illegal immigration. Of course, our border patrol forces armed with technology and drones are a lethal force but that combination alone cannot totally prevent illegal immigrants or hostile forces from entering the United States. Despite having the best soldiers in the world and the most advanced technology, we still couldn’t completely stop enemy infiltration. We used drones, ground radars, human intelligence, image intelligence, and other forms of the most advanced special intelligence in the world. Whether 100 miles or 1,500 miles long, the best military in the world with the best technology in the world could not 100 percent prevent infiltration…and the conditions in most cases were life and death.
