The Legal Insurrection website has a good article on the negative German reactions to President Trump's announced plan to relocate elsewhere 9500 of the 35,000 U.S. troops stationed there. It isn't as if Trump, and ambassador Grenell, disguised that we were unhappy Germany refused to meet their NATO commitment to spend 2% of GDP on defense.
The article doesn't say so, but it's likely we will further reduce U.S. troop strength there. Some will relocate to Poland or the Baltic republics where they can continue to be a tripwire against Russian invasion, some will come home.
It is long since time Germany stopped free-riding on the U.S. taxpayer, relying on us to pay for their defense while they spend lavishly on social welfare programs. They are the economic powerhouse of Europe.
