Exporting democracy? That assumes that the US has democracy to begin with, something that some academics outside of the US question. Although the US currently is exibiting all the "classic" signs of fascism, it is closer to the mark to suggest that the US is really an oligarchy. The difference between the current US oligarchy and ones in the past, is that in the US, the elite tends to slowly change in membership over time. Nobility is not linked to land or heredity.
The US needs to "export" democracy, not for the sake of exporting "virtures" that will allow the rest of the world to play nice, but rather, to give the masses a reason to allow the oligarchy to continue to wage war, and to expend the "throwaway" elements of US society.
Lets face it, the US is less interested in having a democratic neighbour than in having a willing economic colony. Lets remember some "democratic" US allies: The Shaw of Iran, Marcos, Noriega, Saudi Arabia, Pinnocet...
Being democratic is not what the US elite wants. The US elite wants access to cheap labour, cheap resources, wealthy markets.
This bafflegab about exporting democracy is nothing more than a con job.
