Abstract
As the world’s economic and strategic “center of gravity” shifts from the Euro-Atlantic area to the Asia-Pacific, the Indian Ocean is emerging as an increasingly critical trade and energy conduit. This region has long been a strategic backwater for the United States. Moreover, unlike in other critical subregions of Asia, the United States lacks significant host-nation bases and is unlikely to acquire them. The British territory of Diego Garcia, whose location and political reliability give it significant strategic utility, is thus central to US power projection in the Indian Ocean littoral region. The US military’s approach to Diego Garcia reflects an implicit Indian Ocean strategy that seeks to establish a flexible and enduring presence within a critical and contested space. However, Washington needs to move toward an explicit Indian Ocean policy that views the region holistically rather than narrowly viewing separate US Pacific Command, US Central Command, and US Africa Command theaters.
