The strategy was hugely influential, but also quite controversial. Among its more contentious elements were: a shift away from the “two-war” construct—whereby the U.S. military committed to being able to fight two wars simultaneously—to a conducting “a large-scale operation in one region,” and “denying the objectives of—or imposing unacceptable costs on—an opportunistic aggressor in a second region.” The Defense Strategic Guidance directed a “rebalance toward the Asia-Pacific region” away from the counterinsurgency and counterterrorism operations in Middle East.
