Every five years, DoD prepares a review of global defense capabilities extending to 2005 & beyond. This review focuses on the adjustment of forces to reflect the demise of the Warsaw Pact, reductions in DoD infrastructure, a service focus, & other changes. Contents: design, approach, & implementation of the Quadrennial Defense Review; the global security environment; defense strategy; alternative defense postures; forces & manpower; force readiness; transforming U.S. forces for the future; achieving a 21st century defense infrastructure; comments by the chairman of the Joint Chiefs of Staff. Glossary. Assessment by the Nat. Defense Panel.

Global advances in medicine, food, water, energy, microelectronics, communications, defense, and other important sectors of the economy are increasingly driven by discoveries in nanoscience and the development of nanotechnologies. Engaging the nanoscience and technology community in the crafting of national priorities, developing novel approaches for translating fundamental discovery to a technology readiness level appropriate for venture/industry funding, increasing domestic student interest in nanoscience to expand the workforce pipeline, and exploring new ways of coordinating the work of the National Nanotechnology Initiative (NNI) are all imperatives if the United States is to fully reap the societal benefits of nanotechnology. A Quadrennial Review of the National Nanotechnology Initiative provides a framework for a redesign of the NNI and its coordination with the goal of achieving a U.S. resurgence in nanotechnology. This report makes recommendations to improve the value of the NNI's research and development strategy and portfolio to the economic prosperity and national security of the United States.

The end of the Cold War ushered in an era of profound change in the international arena and hence in the policymaking environment as well. Yet the changes that have characterized the post-Cold War era have often proceeded at different paces and have at times moved in opposing directions, placing unprecedented strain on policymakers seeking to shape a new national security and military strategy. This report describes the challenges policymakers have faced as seen through the lens of the three major force structure reviews that have taken place over the past decade: the 1990 Base Force, the 1993 Bottom-Up Review, and the 1997 Quadrennial Defense Review. The report focuses on the assumptions, decisions, and outcomes associated with these reviews as well as the planning and execution of each. It concludes that all three reviews fell short of fully apprehending the demands of the emerging threat environment, and the budgets that would be needed and afforded, resulting in a growing imbalance between strategy, forces, and resources over the decade. Accordingly, the report recommends that future defense planners adopt an assumption-based approach in which key planning assumptions are continually reassessed with a view toward recognizing--and rapidly responding to--emerging gaps and shortfalls.
