How does person's citizenship matter in their views? Is it nationalism a.k.a. "our rights are more important than theirs"? When you think of something like that, how can you morally justify it? You can't. Nationalism is irrational. What Snowden has showed is that USG has been commited in acts which are illegal for mere mortals to commit. Somehow NSA is all good doing this though -- on what moral grounds? Who can honestly claim that its not morally shady to put governmental instiutions above the law, and let it violate the rights of foreigners who have absolutely no power against it, not even the slight bit of political power via voting? Somehow acts against them is all easy to accept without evaluating the ethics, after all they Chinese are some commies and "idk lol". How is military surveillance reasoned during peace time and when it targets civilians? The fact that "others do it too" is no justification.
