>For a reason nobody understands, Germany is like an US satellite in everything it does

I don’t see what’s surprising about this. In the post-war period, most of Europe was hostile to German empowerment, from initial opposition to West Germany’s inclusion in NATO to later resistance to German reunification. The presence of tens of thousands of US troops in Germany also required more diplomatic communication and alignment to maintain status of forces agreements.

The status quo has only really changed in the last twenty years.
