As the 21st century unfold, the dynamics of population growth, settlement patterns, and movement across borders are certain to have an effect on international security. Demographic shifts in political environments that are already tense as a result of territorial disputes, ethnic rivalries, ideological divides, or environmental stresses may provide just enough pressure to spark a violent conflict or perhaps even outright war.

This report presents a framework for assessing U.S. Army International Activities (AIA). It also provides a matrix of eight AIA "ends," derived from top-level national and Army guidance, and eight AIA "ways," which summarize the various capabilities inherent in AIA programs. In addition, the report describes the new online AIA Knowledge Sharing System (AIAKSS) that is being used to solicit programmatic and assessment data from AIA officials in the Army's Major Commands.

Creates six alternative future worlds for the 2025 timeframe and draws out the implications of those worlds for U.S. Army force size, structure, and design. What should the U.S. Army look like in 20 years? Using the tool of alternative futures analysis, this study attempts to help the Army with force planning for the 2025 era. It lays out a spectrum of different Ofuture worldsO to illustrate the complete universe of future missions. Analyzing possible trends across five key areas (geopolitics, economics, demographics, technology, and environment), the study defines six alternative futures and postulates an appropriate OArmy typeO for each one.

How does the Army plan to ensure its continued access to potential trouble spots around the world? The authors developed scenarios and conducted political-military games to determine what strategies, tactics, and capabilities potential adversaries might use to complicate U.S. access to key areas and how effective the U.S. counters to these tactics are. They were sanguine about the ability of the U.S. to prevail in the short-term but also identified several conc erns and suggested areas of improvement, including expanding the number of in-theater bases that might be available; enhancing the flexibility and deployability of U.S. forces to more austere bases; and upgrading detection, warning, and force protection measures.
