I was taking your claims somewhat seriously until you massively misrepresented the very case for which you even provide an article. Now I guess all of what you are saying is either massive misrepresentation or plain false.
The guy was passing info about German agents to the US, not about foreigners/dissidents, and is facing life in prison for it. Embarrassing to betray your country and job for €1600/month. But it would be pretty odd if the German intelligence had a strategy of passing info about its own agents to the US.
I conclude that PT is likely an exception and the rest above probably made up conspiracy theories.
