Even if a large part can sometime fells inconfortable with Bush positions (and just recently), i dont think there is any matter for a "new revolution", they are not convinced that they have a real rulling/leading class and therefore will not act. They believe they are in control, if they work hard they will be rewarded, and the rest is god will.

it is a mistake to view the american leadership/democracy with European eyes because even if a part of the population can disagree more or less deeply with the leadership, it is only at the margin :

God makes America the greatest nation in the world (and thus everything is fine in US (at least better than anywhere else)) and the peace is dictated by the strongest, and the strongest has to remain america, no matter what, because they are the good guys.

They are not convince that they have a real rulling/leading class and therefore will not act
