Execution? A few years of imprisonment at worst. Trump has pardoned worse people (the guy from SilkRoad for instance).
Russia may execute him anytime though. And his family. Easy to pretend he was killed by an Ukrainian bombing.
Well when Trump pardons him, he'll come back. Trump won't pardon him, because Trump supports deep state mass surveillance.
