As we come up on the 8th anniversary of the 9/11 attack, there is a clear need to reflect on those past 8 years, and the effect that one event has had on not just the US, but on the greater world.
Certainly, as an attack, it was devastating. 3000 dead in a single multi-faceted attack (19 hijackers, 2,974 killed, and 24 still missing). However, those 3000 have shaped foreign policy around the world, has spawned several wars, shaped governments, and in many cases massively changed countries.
