They don't need him to be physically in the country for that though. What he leaked is proof enough and there's plenty of evidence that's come to light since. I do wonder how easy it'd be for him to leave if the US welcomed him back and he was willing to risk returning though
There are recent trends to suggest they could

He's got more moral integrity than all of us combined. But nice high horse you have there.

Russia actually did the legally correct action, in giving refuge to a stateless person.

It would probably have ruined his life, but being a martyr makes an even stronger point.
Instead he chose to live a (hopefully) good life in Russia, I mean, good for him. The archive is out, he did his thing, he doesn't have anymore duty to anyone. But he pretty much burned his chance to be recognized as a hero in the US. He has his chance in other countries however. He has overwhelming support in countries like Germany and the rest of western Europe, these are nice countries that value privacy and freedom, that's probably where he should go (should he want to and can leave Russia) instead of the US.
A disgrace that although he is available and what he revealed is now more relevant than ever, he has been buried in the media, which is another continuous signal on the limits of freedom vs elite interests and control.
A hero of the world, not a hero of the US. That's what I wanted to say.
Not wanting to be subjected to https://en.wikipedia.org/wiki/Abu_Ghraib_torture_and_prisone... doesn't unmake someone a hero
