A quarter-century has passed since the morning the world fractured. For the educators standing at the whiteboard today, a daunting demographic threshold has been crossed. Every single student sitting in a K-12 classroom has no lived memory of Sept. 11, 2001. To them, the thick black smoke pouring from the twin towers is not cultural trauma. The gash in the side of the Pentagon is not a memory. The quiet field in Shanksville, Pennsylvania, is just a place. These moments are lines in a textbook. Not for me. I get no reprieve from the pain. 

As the horizon of personal memory fades, America faces a crucial test of historical preservation. We are watching the transformation of a contemporary tragedy into an enduring national epic. This shift mirrors how past generations institutionalized the memory of the Alamo. Texans bound their identity to the sacrifices at San Antonio. They did this to anchor their values of defiance and liberty. Today, American education must firmly secure the lessons of 9/11. It is not merely an act of mourning. It is an act of cultural survival.
