If and when the "wall" is built it will be America's version of France's MAGINOT LINE. Any other that would be a "divinely fine sublime"?

MAGINOT LINE

A line of fortifications built by France to keep Germans from invading their country.

It is a metaphor for a very expensive effort to protect but can only offer a FALSE sense of security.


What other "MAGINOT" lines are there figuratively or literally?


Is QANON a Pumpkina** maginot line? To keep who from what and why?
