I practically bounced out of my chair when I first had the thought. He really would be a good Bolshevik! Leaving aside the partiinost issue, but that became much less important once Stalin died, anyway. As long as he mouths the platitudes, why worry about how sincere it is?

Especially given that being part of the Winter Soldier is a passport to comfort for everyone involved. Crimean vacations! Elite food packets! Occasional foreign travel! (For assassinations, but whatever. The actual killing part doesn't take that long. Still some time to swing by the Louvre afterward.) No one's going to rock that boat.
