As the United States and its allies prepare to withdraw most of their military forces from Afghanistan and following the end of the war in Iraq, fundamental questions have arisen over the future of American landpower. Among them are the role of allies and partners in terms of contributing to the safeguarding of shared global interests, the implications of the Pacific rebalancing for American alliances worldwide, and the role of Landpower in identifying, developing, and maintaining critical alliances, partnerships, and other relationships. To examine these and other questions, as well as to formulate potential solutions to the challenges facing U.S. national security in the coming decade, the U.S. Army War College gathered a panel of experts on alliances and partnerships for the 24th Annual Strategy Conference in Carlisle, PA. Conducted on April 9-11, 2013, the conference explored American landpower implications associated with an evolving national security strategy. The panel devoted to alliances and partnerships featured expert presentations based on the papers in this edited volume. Their analyses provided the U.S. Army and the U.S. Department of Defense with invaluable strategic assessments and insights.
