Why does a liberal German mayor not work with Americans?

People officially tend to address it politely in public, but within some private circles it doesn't come across as nice or cooperative at all, and I am speaking of the relationship in Heidelberg between Americans and mayoress Beate Weber's city government. It isn't a state secret that Americans, who have long been stalwart supporters and good neighbors of Heidelbergers, are planning basically a forced relocation to Wiesbaden for their military forces because of Weber's liberal nonsense and insensitive remarks to the press on occasion regarding relations with the U.S. The mayoress didn't even see fit to attend a session in Washington attended more than a year ago by, I think, ALL other mayors in affected German cities to lobby U.S. Congresspeople to not close installations in Germany, which remain so critical to local economies & employment. Hello! I am not German, but based what I have seen and experienced in or out of the loop my last 13 years here, I would say she should go instead!
