Get stuffed!
Snowden made the ultimate sacrifice for the USA and its Constitution.
I was put in a similar situation at one time: I was read-into a top secret program and the only part that required that level of clearance was:
"We are intentionally breaking the law and going against expressed Congressional cancelation of the project by continuing to fund using a slush fund created from black project funding that isn't on the public record".
I was faced with the same situation Snowden faced: 1) whistle blow about it, 2) cooperate with it by aiding and abetting illegal acts that could easily be considered treason, or 3) quit and have nothing to do with it.
I took the last option which is almost as cowardly as going along but marginally more moral. I've never worked on any DOD program since and I will not help or work on any DOD program ever.
Snowden went above and beyond in what he did and he was right in a very SELF-sacrificial way. He's a hero for that.
The fucking CCP does not exist, clown! Russia is more of Christian nation now than either the US is now or than the CCP ever was! Giving sanctuary like this is far more Christian that what anyone would get for the US government in the last few decades.
He'd likely be killed before he makes it to trial if he comes back so honestly I don't blame him. I'm sure he sees the irony of this because CORRECTLY it doesn't make the US seem like the bastion of freedom, due process or good. Because if you haven't noticed, the country is not remotely living up to its own founding principles or Constitution particularly recently.
Yeah, "why worry; I've done nothing wrong". That's NOT how reality works - you can be prosecuted/persecuted even doing "nothing wrong." From my experience it's only a matter of time and sheep like you will be the first to be sacrificed.
