I think that from a purely technical point of view there isn't a division here: if the NSA has gained access to basically everything (mobile networks, ISPs, landlines, OSs etc) and they're using the access to hoover up all the private data of citizens then logically our allies and enemies know they are also being targeted don't they? Why would the NSA be using God Mode domestically but restricting itself abroad?

So Snowden even revealed everything or nothing. He couldn't only spill half the beans!
