The thing is that Russia and China are not heavily spying on Germany, despite the fact, that they don't even have such close relationships as US and Germany [before]
Despite? :) Americans can freely spy in Germany because of the close relationship. In fact, thanks to our close relationship, we hand our data over for free in many cases (SWIFT, zomg!).
Lol. Of course they are, but German people are not very smart. They're upset their allies spy on them for their own protection, but if their enemies do that it's normal and not even a reason to cool relationships!
