Our History, Lost

I am not sanguine that Americans are remembering Pearl Harbor today as vast swathes of our populace do not seem to recall a much more recent event. How can our citizenry commemorate December 7,1941 when they seem all too often to forget September 11, 2001? It is a shame that as the World War II generation fades away that the level of ignorance about America's past (in our Information Age, when learning history should be so easy) has never been higher.
