Well Merkel has been very upset over the spying. So has France.
From a European point of view:
The bitter truth is that you Americans are going to pay a high price. We understood that except of the UK, NZ, Australia and Canada (maybe you spy on them too) the US obviously has no friends. Therefore it might be reasonable to rethink our relationship to America. Nothing fast but relevant in the long term.
Fact is, that US influence and power on this planet reached its maximum two decades ago and is now declining in a breathtaking way. Therefore America is not that important to us Europeans as it was in the past. Not so far from now we can do perfectly without the US.
Between friends it is not important if one is strong or not. Your actual weakness (espechially in economic terms) was never a big question on our side of the Atlantic. To my (German) generation (I am 45) the US were the Berlin airlift and JFK saying “I am a Berliner”. As most of my German fellows I visited your country a few times. Therefore we feel very sorry now about the experience that friendship and personal relations obiously count that little in the US. It is a new face of America. A nation that betrays its “friends” and steals the secrets of its partners. Please do not bring forward the argument of your ridiculous “war on terror”. Nobody believes in this BS anymore.
We observe the contemporary discussion quite closely. To us the problem is not Obama and his helpless handling of this affair, the real problem is the widespread ignorance in your country. The bitter fact that normal Americans obviously do not care about the treason of allies.
After all it is sad.
