Annan closed his Penn State address with a direct challenge to the graduates that echoed the central lesson of the twentieth century: isolationism is an illusion. He reminded them that their grandparents' generation had learned the hard way — through Pearl Harbor and the Holocaust — that global problems cannot be ignored, and that their own generation had relearned this lesson through 9/11. The Secretary-General's final message was one of radical interdependence: the fate of a refugee in Darfur, a tsunami survivor in Indonesia, and a graduate walking across the stage in State College, Pennsylvania, are all connected. The cause of 'larger freedom' — the idea that no one is truly free until everyone has basic rights, security, and dignity — should not be an abstraction but a personal commitment.
