Whether you agree with what Snowden did or not (I for one do not), dude is a serious drama queen. This is somewhat typical of his generation. Everything is just so much more bigger and more important because it happens to them .
Being from Snowden's generation -- I'm the same age -- I have to say that I for one am personally shocked by the entire NSA spying incident and the subsequent witch-hunt of Snowden himself. Not surprised, but still despite myself, shocked.
Despite having grown a warty hide of cynicism over the last decade, despite having watched western society fail again and again over the last 10 years, despite having suspected the truth for many years already, the sheer scale and nakedness of the NSA's programs has pierced right down to the soft kernel of hope for the world instilled in me during the 1990s. The brazen outrage of the NSA and US military, the absurdly exaggerated charges against Snowden, and the relentless and petty retaliation by the US government have cast present reality back into a past which I was raised to believe would never reoccur.
Snowden is a hero. He's a straight up hero. He gave up reward, riches, happiness, and his own future for the sake of his principles and his fellow countrymen. People in the US should build a statue in his honour. Instead, they're howling like fascists for satisfaction.
If Snowden returns to the United States, I don't think he will get a day in open court. I doubt he will see a military tribunal. After everything that has happened, after just how wrong the world has become, it would not surprise me if Snowden was simply disappeared. It would shock me yes, but not surprise me.
