WWI is too often ignored. It was brutal beyond belief. All those who like to ridicule the French as cheese eating surrender monkeys know absolutely nothing about The Great War.
The World Wars were a demographic disaster for Europe.
10’s of millions of the best men slaughtered.
To me it explains much of the world, especially Europe.
The U.S. should have stayed out of WWI.
Bunch of dying European empires battling to see who was the toughest.
