The last seven decades without war among the great powers – what historians describe as “the long peace” – is a remarkable achievement. “This is a rare and unusual fact if you look at the last few thousand years of history,” said Graham Allison, director of the Belfer Center and moderator of the IDEASpHERE panel “Winning the Peace.” “Furthermore, it is no accident. Wise choices by statesmen have contributed to ‘the long peace,’ which has allowed many generations to live their lives.”

This paper explains changes in NATO's nationbuilding strategy for Afghanistan over time as an internal push-and-pull struggle between the major NATO contributors. It distinguishes between he "light footprint" phase, which had numerous problems connected to limited resources and growing insurgency (2003–2008), NATO's adoption of a comprehensive approach (CSPMP) and counterinsurgency (COIN) strategy (2009–2011), the transition and drawdown (2011–2014), and the Enduring Partnership (beyond 2014). The paper explains NATO's drawdown, stressing both increased budgetary strictures compelling decisionmakers to focus on domestic concerns nd predominant national narratives connected to a protracted stabilization effort in Afghanistan.

Despite substantial progress in improving nuclear security in recent years, there is more to be done.  The threats of nuclear theft and terrorism remain very real.  This paper recommends learning from the much stronger national and international efforts in nuclear safety, and in particular taking steps to build international understanding of the threat; establish effective performance objectives; assure performance; train and certify needed personnel; build security culture and exchange best practices; reduce the number of sites that need to be protected; and strengthen the international framework and continue the dialogue once leaders are no longer meeting regularly at the summit level.

Nearly all of the 190 signatories to the Nuclear Non-Proliferation Treaty (NPT) agree that the forty-two-year-old treaty is fragile and in need of fundamental reform. But gaining consensus on how to fix the NPT will require reconciling the sharply differing views of nuclear weapon states and non-nuclear weapon states. Strengthening the international rules is increasingly important as dozens of countries, including some with unstable political environments, explore nuclear energy. The result is an ever-increasing distribution of this technology. In this paper, Steven E. Miller outlines the main points of contention within the NPT regime and identifies the issues that have made reform so difficult.

The United States has a complex, multi-agency structure to plan, synchronize, and execute foreign policy and national security. By statute, the State Department is the lead agency for foreign policy. However, in practice, the much larger and better-funded Department of Defense conducts much of America's foreign policy activity, often with little coordination with the State Department or other relevant agencies. Over the past two decades, the military's Geographic Combatant Commands have taken an increasing lead in planning and executing foreign policy activities around the world. This has often effectively put a military face and voice on America's foreign policy, sometimes to the detriment of broader U.S. goals and relationships. More effective U.S. foreign policy requires greater interagency coordination at all levels and a greater role for the State Department as America's lead agency for foreign policy.

At a crucial moment, this paper analyzes the challenges the international community faces in Afghanistan and finds that five problems have crippled the effort from the beginning – ambiguous objectives, poor coordination, a mismatch of goals and resources, unrealistic expectations about centralized institutions, and inattention to regional dynamics. The authors offer practical, actionable recommendations that will help the international community achieve a positive outcome in Afghanistan and the region.
