I disagree. Let the U.S. Army patrol the border for six months while more BP agents can be hired.
If we were to do that we would have a problem with soldiers smuggling like we do now with the National Guard.
The problem isn’t really manpower. It’s about willpower. In the 50’s Eisnehower was able to encourage one million illegals to go back south and he did it with less than a thousand Border Patrol Agents. Back then the government had the will to enforce immigration law. We have over 11000 agents and we can’t do today what less than a thousand agents did fifty years ago. The government simply doesn’t want to do what is necessary to shut down the border.
