There is something like 40 thousand American soldiers in Germany. Way, way too little to influence actual policy of a rich country with > 80 million people.
I speak German and I can guarantee you that American military presence has approximately zero influence on German politics.
This is not how an "occupied" country works. You know how an occupied country looks like? Like Czechoslovakia after 1968. The Soviet troops were permanently stationed there to cow our own Communists into submission to the Moscow line. Once it became clear that Gorbachev was no longer willing to actually use them for this purpose, the regime disintegrated within a few years.
