I'm not so sure. If Germany doesn't get honest information on the true scale and intention of US spying, they know Snowden will have answers. This is a matter of national security for Germany.

For Germany, this is like discovering their "friendly neighbor" across the street is a peeping tom. The relationship is already compromised.

Exactly. Most Germans accept nearly everything, except if it comes to their privacy. And I'd strongly support such a move.
