That seems to be a narrow interpretation of what OP originally meant as "post 911 world". While direct consequences of that event are localized and ripple effects definitely affected way more than 10% of the world. Think the direct impact on allied countries who had to send troops to Afganistan. Think airtravel security (theatre). Think financial regulation. Darn.. think the following Middle East interventions by Western Allies. You could say that Syrian civil war today with millions of refugees had direct impact of 911 and subsequent western (and not so western) intervention in Middle East.
