According to Wikipedia (http://en.wikipedia.org/wiki/List_of_United_States_Army_inst...) US has 35 existing bases in Germany and has closed 207 (!) bases in the past. Some of the most important (strategic importance and size) are in Germany. To think that such a huge military presence has "exactly zero to do" with how freely German government can make decisions which would be contrary to the US interests is an illusion.
