Ten years after "the events of 9/11," I think two pertinent questions have evolved, both of which help us understand how cultural/national trauma gets absorbed at the level of individuals
What was the post-9/11 moment? What was special about American politics and culture during a period that followed 9/11/2001? How were particular strategies and tactics mobilized to achieve certain cultural and political objectives? How did these strategies and tactics wane over time? Is the post-9/11 moment something that could ever end?
How did the Post-9/11 Moment structure our thinking about the "event" itself? This is related to the possibility of ever being anything other than Post-Traumatic in the wake of the attacks. The "Post-9/11 Moment" might be thought of as a period that begins with standardized modes of national grief and moves to the recent past, where 9/11 is taken as a kind of given in the American consciousness. Perhaps the Post-9/11 moment was the period during which this shift took place.
