In the past seven years, we've also seen the images that have sobered us. We've watched throngs of mourners in Lebanon and Pakistan carrying the caskets of beloved leaders taken by the assassin's hand. We've seen wedding guests in blood-soaked finery staggering from a hotel in Jordan, Afghans and Iraqis blown up in mosques and markets, and trains in London and Madrid ripped apart by bombs. On a clear September day, we saw thousands of our fellow citizens taken from us in an instant. These horrific images serve as a grim reminder: The advance of liberty is opposed by terrorists and extremists, evil men who despise freedom, despise America, and aim to subject millions to their violent rule.
