This study: E Pluribus Unum examines the problem of providing comprehensive Homeland Security. The research follows the ambiguity of Homeland Security (HS) terminology that invariably leads to mission overlap and jurisdictional disputes, as well as the confusion resulting from the lack of a current and over-arching National Security strategy and structure. These deficiencies in strategy and structure result in continuing systemic failures that place the American public at risk. Comparison of the various entities directed to provide HS reveals a multitude of diverse agencies without a cohesive effort. Finally a synopsis of the varied recommendations for NS reform discloses the often pontificated, long-needed reform effort, wherein Homeland Security is considered a critical element of NS. This book proposes that only President-led and congressionally supported NS reform will provide comprehensive Homeland Security.
