Herr Hitler DID build a wall - it’s called the Seigfried Line - to keep the French army out of Germany.
The Siegfried Line dates from WWI, prior to Hitler's ascension. Hitler did build a similar wall he called the "WestWall." It was not effective against Patton.
A bit before my time but... Wasn’t the Seigfried Line built to stop tanks?
Hey! Tank lives matters! That Trump just getting worse and worse! :/
