This first line is almost certainly false. I've only been paying attention to the German & Austrian news for the decade I've been living in Austria. However, for most of that time, reports that the Germans were both cooperating closely with American State Security agencies as well as running their own pervasive & intrusive espionage programs have been a recurring thing.

Even if all those reports are completely baseless, something I find wildly improbable, there's just no way to fairly describe anyone in a position of power as surprised... this has been a topic of discussion for far too long for that.
