You are probably going to have to pirate it. Despite it's importance, I haven't seen it becoming very popular even in the US. It is mostly playing alternative movie theaters, and not that often.
It will be playing on HBO in the US Monday night. I for one am looking forward to seeing it, and will probably show it to friends via HBO Go. However, I have no idea if HBO will be showing it internationally.
Average joe doesn't read wired or the new york times and if he has heard about any of the leaks, he probably thinks "I have nothing to hide so no big deal - USA number one!".
Cinema chains probably don't want to piss off big gov either and the owners are usually politically involved too.
Oscar bump should call up some courage of theaters to be screening it more. You never know with indie films, and documentaries especially are on no predictable timeline for distribution.
