The Maginot line will protect France by making invasion by the Germans so costly as to be impossible./s
This is from Anders Nielson a Danish analyst. The entire thing is good, though focused on drones and the sea change in how warfare has changed. The relevant point he makes is, once territory is taken, the advantage goes to the defense and territory taken, like Latvia, etc. Will likely not be easy to get back.

At least a hundred million mines (or a billion?) will be needed separate Europe from further Russian invasions. Let’s mass produce mines now!
They’ll be in need of those land mines if Russia comes a’ callin’!
In the post WW2 era, virtually anyone maimed or killed by a land mine was done so by one manufactured in the Soviet Union or one of its communist satellites. All those limbless blacks in Rhodesia... commie land mines.
