In the poster of the film the character attacks Hitler physically.

In a more updated version, that it took into account the current state of the things in the USA (crisis, job absence, reduction of the workers' income, contempt of the public power to the poor people, public benesses granted to immodest and failed bankers, besides the immoral, illegal and unjust wars of the USA in Middle East), I think that Captain America should be beating another person: Franklin Delano Roosevelt, for instance.

The cycle closes. Quite convinced of his superiority the Americans march impassive for his own Götterdämmerung. We won't miss them.
