BTW here's why I disagree - apart from the widespread domestic surveillance already admitted the NSA has used dragnet foreign surveillance from other five eyes nations like the UK to spy on American communications with no suspicion of wrongdoing, and has attempted dragnet surveillance in other nations like China (text messages). All of those things deserve debate - even on foreign surveillance the NSA should not have a free hand IMHO - they're supposed to target enemies of the US, not engage in blanket surveillance - that's a dangerous and massive expansion of their powers and in the hands of a president like Nixon would be truly terrifying. It also undermines the position of the US in the world and allows nations like China to indulge in cyberattacks with absolutely no moral high ground for the US.
Re where Snowdon goes, I think that has far more to do with pragmatism that his wish-list of most desired countries - from his own words I think he would have preferred to stay in the US and fight this if he felt he'd be given a fair trial, but that has been made impossible by the calls of traitor from the current administration (what they mean of course is traitor to the NSA and administration, not to the country, but those two are confounded).
The alternative interpretation of his actions is that a champion of human rights has been obliged to flee the US and seek refuge with enemies of the US, because he risks imprisonment without bail, torture and indefinite detention at home (all of those have been used in the war on terror in the last decade). It is quite credible that he wouldn't be allowed to state his case or argue his defence as Ellsberg did, and in fact Ellsberg agrees with him on that, and the treatment of Manning justifies his fears. So maybe champions of human rights do now flee the US?
