Its fall showed, that cultural relativism and universal liberalism, where just western delusions. Socialism was a dead ideology by then, but this really attacked western values, insofar, that a dried husk of a imperialist religious ideology, revived with western demand for natural resources (oil) would rather engage in cultural warfare upon western values and society then trying to fix itself.

It was a ringing bell, bringing the attention back to the old ugly worldorder of great games, land-empires and bloody conquest and the inability to isolate from hostile ideologies, even if you are the usa and living on a giant island. Bush went to iraq and the failure to build any working state there- showed not only the failure of neoncons, but also of the whole "all cultures are equal" and academic impotence. There explanation models had nothing for this but tired rehashes of colonial/anti-colonial ideology, no predictions, no real help, just "belief in universal values and western culture, and righton" - and that was it. No help for the 2 billion stuck in religious ember, not real analysis to free the wasted geniuses trapped under burkas. Silence, ideology and absence, thats whats left.
