Unless other schoolyard bullies...
... the US is hellbent to turn away _every_ friend it has.
After all, with all their power, and the proven ruthlessness in using it, what do they need friends for? Enough if everyone is scared enough to let them have their way, isn't it?
I met such bullies in the schoolyard, and be assured there is a (non violent!) way to put them in their place- the rest just has to band together and decide not to be bullied anymore!
Since 9/11 things have turned to the point where the world is not concerned about the next terrorist attack, but about what the US is going to do next. I wonder if they can't see that, if they don't care, or if that's how they want things to be.
Seemingly limitless resources and power with the declared will to use it for ones benefit, a blatantly chauvinistic attitude of the authorities combined with a patriotism on the base that seems to justify just anything as long as it is "us against them", and put on edge by all the enemies they have themselves created by just that...
THAT scares the crap out of me!
More, as every psychologist can confirm, eavesdropping is often a sign of paranoia fueled by the awareness of ones wrongdoing, having a need to check whether others are talking behind ones back, and whether they are on to the eavesdropper.
I believe that is exactly what PRISM is.
