Abstract:
Fortified boundaries are asymmetrical, physical barriers placed along borders. These boundaries are more formidable in structure than conventional boundary lines, but less robust than militarized boundaries. Their goal is to impose costs on infiltrators and in so doing deter or impede infiltration. A novel dataset of all such boundaries worldwide shows that states are constructing these barriers at an accelerating rate. More than half of barrier builders are Muslim-majority states, and so are the vast majority of targets. A multivariate analysis demonstrates that, contrary to conventional wisdom, states that construct such barriers do not tend to suffer disproportionately from terrorism, nor are they apt to be involved in a significant number of territorial disputes. Instead, differences in state wealth and migration rates are the best predictors of barrier construction. Qualitative case studies suggest that the most effective fortified boundaries are found where the initiating state controls the territory beyond a boundary that blocks the only access route into the state.

Abstract:
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. Chaired by the Strategic Studies Institute’s Dr. John R. Deni, the panel devoted to alliances and partnerships featured expert presentations based on the papers in this edited volume by Dr. Sean Kay, Dr. Carol Atkinson, and Dr. William Tow. Their analyses provided the U.S. Army and the U.S. Department of Defense with invaluable strategic assessments and insights.
