re: #175 KGxvi
About two weeks ago there was an incident involving US and Mexican troops:
Because of course the existing border fence is stupidly well north of the actual fucking border.
You have to put border fences inside a border. That is to ensure you don’t inadvertently put it on the other nation’s territory, and you can access both sides of it for maintenance.
The Berlin Wall is the famous example of that. It was just inside the East Berlin border to prevent encroachment on West Berlin territory.
