Whoops, I should have used a less ambiguous sentence: I didn't mean that these opinions were more prevalent in Germany, I mean that they can have much worse consequences.
That sounds more agreeable to me. Although I don't believe it is dangerous for anyone, Germans might shot themselves in the foot.
About that 'not fully sovereign' thing: It's a popular myth. Under the 2+4 agreement Germany regained full sovereignity - the US troops still stationed here are not part of an occupying force.
Yes, that's right, at least technically Germany is a sovereign state (depending a bit on definitions). It became that several times even.
The "right of self-defence for the American army in Germany" is an additional note to the G10-law (an addition to the constitution 1968 on intercepting telecommunications and mail), which grants not only full cooperation of the German intelligence in monitoring all Germans or persons in Germany when asked for by western allies, but also allowed them for the first time to act on their own. This was accepted by W. Brandt in 1968, basically to free German mailmen from having to sift German letters for the western allies (which was the situation before, according to the General treaty from 1952
http://en.wikipedia.org/wiki/General_Treaty when Germany became a sovereign state for the first time after the war. Germany was not allowed an intelligence service, but was obliged to carry out the surveillance.)
To address this, they finally installed a proper German intelligence, but also gave all allied military commanders the legal right to carry out everything from their own preventive intelligence up to use of lethal force. This addition is the legal basis for the currently reported surveillance by (not only US, English and French but also German) intelligence taking place in and outgoing from Germany by NSA and the British. This means that the presence of the troops is the condition for this. Notably, it is not a condition for any surveillance that is carried out from outside Germany.
Now, when Germany became a sovereign state for the second time in 1990, all these treaties and conditions were ratified again in secret and become part of the 2+4 agreement under the term inheritance ("Erbmasse"). Thus, they are all valid to the present day.
That may explain why Merkel was ready to accept all of the "NSA monitors all Germans etc"-news without reacting, but when it was about her phone, she became aware of the dimensions... or possibly it was an election maneuver to keep quiet before, i don't know really.
