Well, yeah. Why should they?
Spying is what countries do on each other, even friendly countries.
I'd like to see a stop to agreements like the five eyes bullshit, and I don't think the NSA needs to archive every single goddamn email and telephone call....but intercepting communications of people from other countries if there is due cause?
No issue what so ever.
And, if you as a private citizen have an issue, you can double up on security because you should assume people are trying to listen regardless. Hell, maybe even your own government is doing the listening.
