In the aftermath of September 11, US strategy has shifted in the Central Asian region from protecting the sovereignty of the southern post-Soviet states to ensuring their stability in light of the dual impacts of energy development and the rising threat of Islamic terrorism. Although US-Russian cooperation has made strides, particularly concerning Russian acquiescence toward US and NATO military engagement in the region, geostrategic rivalry and conflicting economic goals have hindered a joint approach to initiatives regarding the region's energy development. While both agree on the goal of maximising Russian and Caspian gas and petroleum exports, US policy is increasingly prioritising Central Asian energy prosperity as a key factor in the region's ability to contain terrorism. Development of the region's energy resources has therefore become a critical US security concern. Yet, by failing to engage with Russia in a meaningful cooperation that could encourage Moscow to diversify its own energy export prospects, competition between the two powers is likely to reduce, rather than improve, the effectiveness of either in offering the Central Asian states the kind of support they need to strengthen their domestic profiles or withstand the incursion of terrorism.
