Dragan,
Why, you sound like a political science student. Are you really so cynical about the morality of your adopted country? ;-)
We all know the American Hegemony has enormous power and projects it. However, at a time when there is no non-spiritual power on earth that could deny the USA anything physical it desires, one might equally observe that the USA is remarkably restrained in its use of power.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
