The Us - Bases in Germany?

Most of the us. Bases are in east, are in west germany. I think that there was no real need or reason for the americans to open bases in east germany because the whole of the country was now under nato control. And may be, as the geo political situation changes, as the world order changes, even antarctica, unfortunately, may become open to a commercial exploitation. In ito, germany, us and germany russa relations? The first question is about the us. It's difficult from north pole perspective, but much easier from south pole perspectives.
