Remembering and honoring the victims of September 11 is therefore not remotely sufficient. We must engrave their faces and tragically shortened histories on our hearts and in our souls. We must commit ourselves to the only goal that is worthy of their memories: to eradicate the disease that killed them, wherever it is and however long is takes. Their suffering and deaths must fuel our dedication to stamp out this cancer, and, in doing so, save those we love, and those who come after us, from future September elevens and the pain, loneliness and helplessness we experienced on that day two years ago and have lived with every day since then.
