One doesn't even need Snowden to know this. Given even a little reading of the IC's (intelligence community), and more specifically CIA's, history. What else do you think they do all day, if not for spying on other countries?

As mercutio2 mentioned in a reply to your same parent, the controversy w/r/t Snowden is domestic spying.

In the US maybe, but most of the US's supposed "allies", and their citizens, would probably disagree with that interpretation.
