Your ideas about Germany are way behind the time. Many US troops were already pulled out. Starting a business in German is not difficult. Visit any mall or shopping area.
USA has food stamp programs feeding tens of millions of people. You won’t find any such socialist program in Germany.
I agree pull out the relatively few forces. Oh, but Germany is a NATO country.
I don’t disparage Germany or Germans, six of my eight great-grandparents emigrated from Germany.
But there is a characteristic, or common tendency if you will, to create order out of disorder, and often to be quite assertive when doing so.
Ride across Europe in a third class couchette with five Germans and you will agree.
There are problems when the wish to order things bumps up against non-Germans, as is now occurring in the EU.
Obviously, the use of military force to unite Europe ended in disaster. But the use of economic power to unite and order Europe along North German lines has its limits, as well.
Congratulations on your wonderful domestic economy and society. Hopefully you will not be too inconvenienced by the recent influx of primitives.
But do understand that the further out the borders of the German economic interest zone go, the firmer the resistance will become.
