Honestly, the "border war" could be won in a very short period of time if both countries were serious about solving it ...
While it would be (nearly) impossible to prevent all border crossings, if both countries cracked down on it they would (probably) be able to catch 66% to 75% of people trying to cross the border which would discourage 66% to 75% of people from trying to cross the border; resulting in less than 10% as many people, guns and illegal drugs crossing the border.
At 10% of the volume, cartels would be forced to change strategy or go out of business; and the tensions surrounding the border would go away.
