Re: Other things about the Winter Soldier we'd like to see?
Should the Soviets be the ones to be behind the Winter Soldier? I think yes.
It lends historical relevance, and ties into Steve being a man out of time. When he went order the Soviets were their allies, when he comes back, he finds out that they'd been in a bitter cold war for decades, during which they'd subjugated his best friend to a fate worse than death.
I mean people say that they had HYDRA instead of Nazis, but the USSR doesn't have the same taboo attached to as portraying Nazis in fiction does.
Not to mention, HYDRA was Nazi, at least in origin. Similarly, Winter Soldier, and whoever is pulling his strings, could be originally Soviet, but are not so in the present.
