Not to say that Snowden planned to "defect" to Russia. But we're seeing how skillfully the FSB played the Trump campaign. Let's consider the possibility that they played Snowden and Greenwald as well.
Someone's being played, that's for sure.
As a non-American, what I find amusing is how quickly the rhetoric changed from before the election "elections can't be rigged/influenced, Trump should stop complaining and such claims undermine democracy" to "Russia/Trump hacked^H^H^H^H^H^H colluded to influence the election and undermine democracy" once Trump won.
Heads I win, tails you lose.
