David McCullough: History as a source of strength
Historian David McCullough talks about the history of the United States, and how we can look back and gain strength from our past.
McCullough says people need to remember that others have made it through difficult and dangerous times, and so can we.

McCullough says history is important in education because it tells us what people believed in and how they suffered for achievements.
