From the White House: Of course, this burden is not ours alone to bear. This is not just America’s war. Since 9/11, al Qaeda’s safe havens have been the source of attacks against London and Amman and Bali. The people and governments of both Afghanistan and Pakistan are endangered. And the stakes are even higher within a nuclear-armed Pakistan, because we know that al Qaeda and other extremists seek nuclear weapons, and we have every reason to believe that they would use them.

These facts compel us to act along with our friends and allies. Our overarching goal remains the same: to disrupt, dismantle, and defeat al Qaeda in Afghanistan and Pakistan, and to prevent its capacity to threaten America and our allies in the future.

Because this is an international effort, I’ve asked that our commitment be joined by contributions from our allies. Some have already provided additional troops, and we’re confident that there will be further contributions in the days and weeks ahead. Our friends have fought and bled and died alongside us in Afghanistan. And now, we must come together to end this war successfully. For what’s at stake is not simply a test of NATO’s credibility — what’s at stake is the security of our allies, and the common security of the world…

Since the days of Franklin Roosevelt, and the service and sacrifice of our grandparents and great-grandparents, our country has borne a special burden in global affairs. We have spilled American blood in many countries on multiple continents. We have spent our revenue to help others rebuild from rubble and develop their own economies. We have joined with others to develop an architecture of institutions — from the United Nations to NATO to the World Bank — that provide for the common security and prosperity of human beings.

We have not always been thanked for these efforts, and we have at times made mistakes. But more than any other nation, the United States of America has underwritten global security for over six decades — a time that, for all its problems, has seen walls come down, and markets open, and billions lifted from poverty, unparalleled scientific progress and advancing frontiers of human liberty.
