What is the national interest? This is a question that I took up in 2000 in these pages. That was a time that we as a nation revealingly called "the post-Cold War era." We knew better where we had been than where we were going. Yet monumental changes were unfolding -- changes that were recognized at the time but whose implications were largely unclear.
And then came the attacks of September 11, 2001. As in the aftermath of the attack on Pearl Harbor in 1941, the United States was swept into a fundamentally different world. We were called to lead with a new urgency and with a new perspective on what constituted threats and what might emerge as opportunities. And as with previous strategic shocks, one can cite elements of both continuity and change in our foreign policy since the attacks of September 11.
What has not changed is that our relations with traditional and emerging great powers still matter to the successful conduct of policy. Thus, my admonition in 2000 that we should seek to get right the "relationships with the big powers" -- Russia, China, and emerging powers such as India and Brazil -- has consistently guided us. As before, our alliances in the Americas, Europe, and Asia remain the pillars of the international order, and we are now transforming them to meet the challenges of a new era.

As globalization strengthens some states, it exposes and exacerbates the failings of many others -- those too weak or poorly governed to address challenges within their borders and prevent them from spilling out and destabilizing the international order. In this strategic environment, it is vital to our national security that states be willing and able to meet the full range of their sovereign responsibilities, both beyond their borders and within them. This new reality has led
