We know the NSA eavesdropped on Merkel, it's been admitted, essentially. The more interesting thing to ponder is, was it just one instance of listening to a single call, or has the NSA been listening in on pretty much ALL her calls? I think we know the answer to that. And, is Merkel the only world leader, person of importance, etc., being monitored? I think we know the answer to that, too. Pretty much EVERY world leader, and person of importance is being monitored as long as they are able to, and there's little doubt anyone they can't listen in on is particularly interesting just for that reason alone and gets extra attention. In any event, those who can't be monitored are few and far between.
When a new US President enters office, he's briefed by the intelligence community about all the interesting things known around the world that are not common knowledge. Of course, some of those things are probably bogus because anyone with any brains figures they're being spied upon and the best way to deal with that is to make use of it by feeding it with disinformation. Be that as it may, any President thinks he knows far more about the goings on in this world than the American public (and he probably does, that's not really saying much). The President undoubtedly knows enough to have a jump on the stock market, if he wants it, by knowing what moves world leaders are about to make. And the American public is then expected to be knowledgeable enough to vote intelligently? No, this excess information has turned the American government into a cynical paternalistic and tyrannical force, that more accessible health care, a little bit of social security, lower taxes, television and ready access to guns is supposed to fix. Sorry, but that's just not enough to make it any less cynical, less paternalistic, or less tyrannical.
