  • NATO Missile Defense and the European Phased Adaptive Approach: The Implications of Burden-Sharing and the Underappreciated Role of the U.S. Army

    October 18, 2013

    Authored by Mr. Steven J. Whitmore, Dr. John R. Deni.
    View the Executive Summary

    NATO's ballistic missile defense initiative remains a work in progress, but a lack of interceptor and sensor contributions on the part of the European allies is likely to have significant implications for the U.S. Army. In particular, the U.S. Army is likely to face increased manpower demands, materiel requirements, and training needs in order to meet the demand signal created by the NATO ballistic missile defense program.

  • The Future of American Landpower: Does Forward Presence Still Matter? The Case of the Army in Europe

    October 09, 2012

    Authored by Dr. John R. Deni.
    View the Executive Summary

    The January 2012 announcement that the United States would reduce the number of Brigade Combat Teams in Europe captured media, popular, and scholarly attention, prompting many to ask: Is the United States turning its back on Europe as it pivots to Asia? Do the Europeans have the wherewithal to defend themselves? Are forward-based U.S. land forces necessary at all? Given the necessity of capable, interoperable coalition partners for the future security threats Washington most expects to encounter, the role of America’s forward military presence in Europe remains as vital as it was at the dawn of the Cold War, but for different reasons. Dr. Deni’s monograph forms a critical datapoint in the ongoing dialogue regarding the future of American Landpower.
