In commemoration of the tenth anniversary of 9/11, many people spent the weekend declaring, “We should never forget.” Of course, we never should forget the tragedies of that day and the lessons we’ve learned as a result.

But I can’t help but think, as passionately as people demand and promise remembrance, that we, as a nation, are doomed to forget.

How do I know? Because we’ve already forgotten a tragedy of even greater magnitude.
