Let's break this down. You'd have to:
not know the difference between Russia and the Soviet Union
not know that Russia wasn't where Snowden was trying to end up
not understand the difference between a political defector (defecting to a political system that doesn't exist anymore!) and a guy trying to evade prosecution
I don't say this very often but I don't think people are as dumb as you think they are. People who think Snowden is a traitor would feel the same if he were in Iceland or something right now.
