Until recently, it was considered ridiculous to think that the NSA is spying on citizens of countries allied to the US. Now we have proof.

Ridiculous by whom? It wouldn't surprise me if we spied on our allies citizens and then sold the intelligence to our allies so they didn't have to.

I mean, we have in the past warned allies that one of their citizens was planning an attack. It should have been obvious that meant we were monitoring their citizens.

It was considered ridiculous by the mainstream. If I told that to some of my friends, they would have thought I'm crazy. Not anymore.
