The forces of barbarism have clearly struck an extraordinary blow against freedom this morning. This is not about the United States alone. It is about the survival of free societies in an open, interconnected world where forces deeply hostile to freedom can wage a new kind of war against our humanity and our success. Words fail me. But my hope is that this will awaken the sleeping tiger. When our shock recedes, our rage must be steady and resolute and unforgiving. The response must be disproportionate to the crime and must hold those states and governments that have tolerated this evil accountable. This is the single most devastating act of war since Nagasaki. It is the first time that an enemy force has invaded the precincts of the American capital since the early nineteenth century. It is more dangerous than Pearl Harbor. And it is a reminder that the forces of resentment and evil – so prominent only recently in the Durban conference – can no longer be appeased. They must be destroyed – systematically, durably, irrevocably. Perhaps now we will summon the will to do it.
