There is a language barrier between vets and the civilian population. They speak different languages.

Sometimes it can seem that history is turning in a wide arc, toward an unknown shore. Yet the destination of history is determined by human action, and every great movement of history comes to a point of choosing.

It would send an unbelievably terrible signal to reformers across the region. It would say we've abandoned our desire to change the conditions that create terror.

Tonight, I ask for your prayers for all those who grieve, for the children whose worlds have been shattered, for all whose sense of safety and security has been threatened. And I pray they will be comforted by a power greater than any of us, spoken through the ages in Psalm 23: "Even though I walk through the valley of the shadow of death, I fear no evil, for You are with me."

The advance of human freedom - the great achievement of our time, and the great hope of every time - now depends on us. Our nation - this generation - will lift a dark threat of violence from our people and our future. We will rally the world to this cause by our efforts, by our courage. We will not tire, we will not falter, and we will not fail.

Wisdom and strength, and my family, is what I'd like for you to pray for.
