Mostly BSing you, the beer has kicked in. But we should have armed posts on the border that a fence cannot be built on. It is true that on some parts of the U.S./Mexico border, some of the terrain isn’t suitable for a fence.
If it’s a sheer cliff 100 feet high, sure.
Heres the thing. Any non complete fence acts as a funnel.
If you build a complete fence, the dems cant use eco law like they did in AZ to put land off limits to Americans and simply allow free access to illegals. A full fence is more to stop Dems than illegals really. But it works on both.
Plus, after 6 billion bucks, few will allow that to be wasted tearing it down.
