Let’s be real here, the Federal Republc of Germany has done nothing of importance since 1945 without at least consent, if not by the instruction, of the US empire. The post war industrialization was funded with US capital for the benefit of the US capitalist class, and now the deindustrialization is for the benefit (at least they perceive it this way) of the US capitalist class.
I think it would be more than embarrassing, it would be destabilizing to admit that the Federal Republic is ultimately little more than a US vassal.
