An interesting piece on 9/11 effects ten years on by Victor Davis Hanson is online at City Journal. I found the end of it especially good:

And so, on the fifth anniversary of September 11 in 2006, the country had become split apart over Iraq, mostly amnesiac about Afghanistan, and receptive to the liberal narrative that the terrorists had won by scaring us into abandoning our values. In contrast, on the tenth anniversary, Americans have come nearly full circle: anxious about renewed violence in Afghanistan, increasingly unconcerned with Iraq, and relieved that postwar homeland security measures have kept them safe.

The common denominator in these ten years? American life under its hypercritical, volatile, and mercurial democracy proves resilient; the Islamic terrorists and their authoritarian sponsors who would destroy it do not. And even after a decade of acrimony, partisan rancor, and stasis, Americans continue to be horrified—and angry—over those who were murdered on September 11. We’ve done our best for ten years to ensure that it cannot happen again.
