I have been calling for us to bring the boys home from Western Europe - Germany especially - since the early 90s when I started going over there and living there. It was obvious even then that they no longer served any purpose. They just allowed the Germans to freeload on the American taxpayer for their national defense.
The only purpose those troops serve is to be a wall between the reinvigorated east and west germany joining with the Ruskies. The german industrial sector is useful to the commies and the Ruskie access to energy is important to Germany, more so than what they get from the EU.
