For the past 19 anniversaries of 9/11, we have commemorated that national tragedy with a certain sense of relief and vindication. On the first anniversary, even as we mourned the 2,977 victims, we could derive some measure of comfort from the fact that we had hunted down their killers, smashed their hideouts, and ousted the 7th century Taliban fanatics who had sheltered and nurtured them.
By the 10th anniversary, we could mark the death of Osama Bin Laden.
What emotions will we experience on the 20th anniversary?
