That's an over-simplistic view of things and implies that Snowden is perforce the lesser fool. I think it's rather more the reality that Snowden has been quite wise in his planning: he is aware that he is putting Russia in a position where Russia will try its darndest to be on its best behavior in sustaining that "asylum-giving, human-rights protecting" image it has recently gotten.
Russia has an "asylum-giving, human-rights protecting" image? Even if you were to believe that Russia is acting to protect Snowden out of anything but national self-interest -- does refusing to extradite Snowden cancel out Russia's multiplying authoritarian abuses? Pussy Riot? Navalny? Magnitsky? The "Gay Propaganda" bill?
The notion that Russia is beholden to Snowden to protect its image is ludicrous, although given the grandiosity of some of Snowden's statements, I do not hesitate to consider that Snowden himself might believe it.
No, he probably did not plan on ending up in Russia, but he has been wise in dealing with the situation he was put in with the very limited number of options he had.
That he is still alive, well, mentally sound, able to freely speak to journalists (and American politicians) at free will -- and finally now "free" to leave the airport is evidence that he's been wise in making decisions.
> Russia protecting human rights? OMFG
That is an irrelevant and uninformed statement with regards to Snowden's situation and his decision to seek asylum in Russia. It was very simply one of the few rational options to pursue in order for him to remain a 'free man', as has been made abundantly clear by now.
