You can even see the political undertones with the statement about India and Pakistan in the official announcement.
Also, I really don’t think Snowden should get a Peace Prize. It’s not like this opinion of yours that Snowden would be a worthy recipient is some kind of objective truth or even self-evident.
Snowden seems pretty subservient to Putin right now, and relies completely on him for his continued safety and asylum in Russia. He's in a pretty weak spot since Putin can dispense with him any time he wishes - either deport him or have him disappear, and the US won't raise a finger - but will keep him around as long as he's politically useful.
Read his autobiography. He makes no apologies for the fact that he embraced guerrilla warfare, and actively waged war against the state. Initially, yes, he and the ANC adopted peaceful means, but when the South African state shutdown and outlawed all the peaceful means at their disposal (e.g. strikes, demonstrations, etc.), he supported, encouraged and actively participated in fighting against the State. Hell, he co-founded Umkhonto we Sizwe, the armed wing of the ANC, after the Sharpville massacre. Even after his release from prison, he refused to disarm the ANC since the same apartheid state apparatus that he fought against still existed.
Mandela is undoubtedly a great man of peace, and he did manage to bring about an incredible transformation in South Africa, but to say he did it through peaceful means is just incorrect.
Also, one of the major incentives to maintain a strong defense is to keep from having to use it. Of course this principle, like anything else, can be taken too far.
Those of us from pacifist religious traditions would disagree.
