Re: James Buchanan Barnes aka The Winter Solider
I think Bucky, besides being a vehicle to show that despite being a perfect human Steve is still an outsider because he is a perfect human, Bucky could also represent the portion of young Americans who wanted so badly to help fight in the war that they sneaked in some how. I have heard a few stories about how a guy lied about his age to get into the army or navy to help in the war.
Barnes is too young, and a talkative guy. He is also the son of another popular soldier who died before the war. So Bucky could sort of sneak into the war on his father's reputation.
