The story of America has unfolded over a relatively short period of time, yet it has captured the world's imagination ever since the Pilgrims first set foot on these shores. Founded on the highest principles, and sustained through hard work, sacrifice, ingenuity, and devotion, the American legacy has been passed on from one generation to the next. The events of September 11, 2001, shocked and horrified Americans. They served as a reminder that even a nation as mighty as the United States must always be prepared to defend itself. President Bush spoke for the nation when he said, "None of us will ever forget this day."
