Despite changes in the global security environment stemming from the end of the Cold War, U.S. overseas bases remain vulnerable to ballistic and cruise missiles. This monograph, by Joel Wuthnow, explains how technical, strategic, and political factors will pose complex and discrete concerns, and makes a series of policy recommendations for how best to diminish the threat. The monograph is being published under the Strategic Studies Institute's External Research Associates Program. We are publishing it as a contribution to the continuing dialogue on the U.S. military's strategy of engagement.
