FWIW I'm *still* a paranoid freak. I don't believe that ANY centralization of power under the control of humans can be trusted. People are corruptible, and worse, some among them are psychotically driven to seek positions of power. At some point any position of power will fall under the control of one of them, and his (these characters are extremely predominately male) first act will be to extend his current power, and his second will be to increase his immunity to repercussions for his illegal, or at least immoral, actions.
Please note that this doesn't mean I think there is any reasonable way to eliminate such concentrations of power. What it means is that I think it should be made as difficult as possible to reach such a position by political maneuvering and scheming. To this end sometimes I suggest that the holder of such a position should be selected by lottery among those technically qualified. This will produce an inefficient government, as those selected would be less adept at diplomatic negotiations and compromise. OTOH, look at the current congress, and contemplate whether it could do worse. I am bothered by isolated positions of power such as the POTUS, but my real feeling is that they should be devolved into purely symbolic offices, and the real power should vest in some small committee, selected, as suggested above, by lottery....and not from any small pool of candidates.
OTOH, I can see the value of voting, if not of plurality wins voting. So I am also moderately supportive of Instant Runoff Voting or Condorcet Voting. They would clearly be an improvement over the current system, though they would increase the problem of information overload at election time.
As for Germany...I suspect that their motives are basically economic, but this time it's causing them to make the correct decision. They should not trust a foreign country with their governmental communications.
