U.S. military strategy is undergoing its most serious examination since the end of the Cold War. Led by Secretary of Defense Donald Rumsfeld, this process is designed to assess every dimension of the strategy, including its most basic assumptions and concepts. For the first time in over a decade, everything about U.S. military strategy is subject to question. One of the most important elements of U.S. military strategy for the past ten years has been the belief that a force able to fight two nearly simultaneous major theater wars (MTW) of the DESERT STORM type would be capable of dealing with the full gamut of security challenges that the United States is likely to face. Now nearly every expert on U.S. military strategy agrees that this force shaping paradigm needs a relook.
