9/11 also marks the end of western hegemony as the West destabilized the world and ruined its reputation as a force for good in its pursuit for revenge, leading to the rise of BRICS and other anti-imperial coalitions.

9/11 also coincides with peak imperialism, the final stage of capitalism, which marks the point when increasing exploitation abroad has diminishing returns so capitalists must begin devouring the imperial core, leading to stagflation, enshittification, rent-seeking, and other parasitic activities. This in turn leads to an economically struggling population of former petit-bourgeois, which is a class condition that is especially susceptible to reactionary propaganda, leading to the rise of fascism.

Historians will almost certainly mark 9/11 as the beginning of the end of the American Empire.
