I certainly was interested to learn what the NSA was doing, and very unhappy about the fouth amendment implications. But forget all that.
What specific publicly available info indicates he had nefarious intentions or was an agent of a hostile power?
A related follow-up question is: could his knowledge of our systems and processes somehow have helped Russians do the hacking prior to 2016 US elections? Not that they couldn't have done it without him but did he help in an indirect way?
The only country that has demonstrated the ability to resist pressure to extradite people wanted by the US? Yes.
> ...could his knowledge of our systems and processes somehow have helped Russians do the hacking prior to 2016 US elections?
bwahaha, so now he is involved in muh Russian collusion? The answer is yes, which is what makes your insinuation really funny - they did all the things he would have advised them not to do. So you could interpret that as evidence that he didn't provide them that information, and is therefore not a Russian spy.
If you've got evidence, or even a coherent rationale, that would cast doubt on his motives - I'd love to hear it. No, fleeing to the only country that would be out of the reach of a president who prosecuted more whistleblowers (and reporters) than every prior administration combined... that isn't evidence of Snowden being a Russian spy. That would be like insisting that a prisoner who accepts food from his captor is also expressing approval for his captivity.
BTW, looking back at all the articles about Obama's legacy in regard to whistleblowers, written after the election - darkly predicting that Trump will start jailing reporters because Obama had established the precedent... lol.
