The one positive here....as long as you warn the Germans six weeks ahead of time, they can arrange for 60-percent of their tanks, aircraft, helicopters, subs and patrol boats to be operational.
If I were the bulk of European countries and relying upon the Germans, I’d go ahead and prepare a surrender document ahead of time.
No doubt the cheese eating surrender monkeys have a boiler plate one to just fill in the blank of who they are surrendering to.
The French already have that part handled.
