When the Americans demanded access to every bit of privacy sensitive information regarding EU citizens then there was no problem at all. I've never been to the US and quite frankly with the current state of affairs I also wouldn't want to go there, but even so the US government still wanted to gain access to my bank accounts. We all might be terrists after all.
But now, when its happening to the upper brass themselves, all of a sudden we're in a panic. How typical.
To be honest, given the -IMO- paranoia state of the US I can to some extend understand that they're bugging buildings in Washington. I don't agree with it, but I can see where it's coming from. In fact, I think it was to be expected. After all; its not as private as an embassy.
Still, the rumours that they even infiltrated in several buildings in Brussels is taking it one step too far in my opinion. That almost brings back memories of old Mother Russia where diplomats simply expected to be bugged.
I recall reading a story about a Dutch politician who was on a business trip to Moscow (we're talking the 70's here) and on the last day in his hotel he started talking to his wife how cool it could be if the Russians would give him some Caviare as a 'going away present'. Even mentioned a completely random brand which he just read about that very day in a paper.
Guess what he got before departure, with compliments of the Russian state?
