Actually, I think the view that this has nothing to do with Russia is valid.
And I can see why regular Russians think it's more trouble than it's worth to annoy the USA by protecting Snowden.
Personally I wish it was MY country that had the opportunity and the will to take in Snowden... But I know it's not going to happen, so I hope Russia will take him in, and I'm thinking Russia should be less susceptible to US bullying than most other countries. It's not like the two countries were best friends to start with.
I don't agree with Doomer's view but I understand where he's coming from.
