My ideas are extreme, especially for this board.
Yes, extremely stupid. Putting that many resources on a border has been shown to be stupid over and over through history. Remember the Maginot Line? Or the Siegfried Line? Wasting resources on a border (which in this case has gates and thousands pass through every day) is a shitgibbon type idea, which of course ignores that they then go over it, around it, or under it, but mostly through legal entry points just like what is happening now. Over half of the immigrants come through a point of entry or through an airport, or other port of entry. So you would spend 80% of our overseas military budget to impede less than half of what you are afraid of. What made you into a person so afraid of brown people? They contribute more than they receive in our economy, despite what is said at your Klan meetings.
