In response to recent oil and gas price hikes, recurring blackouts in California, and other symptoms of a U.S. energy crisis, both the Bush administration and the Senate have made national energy security a top priority. Whereas the Bush team has advocated increased domestic energy production, the Senate?now under Democratic control?has emphasized conservation. Neither side, however, has given adequate attention to international energy policy, particularly U.S. policy toward the Caspian region. The countries surrounding the Caspian Sea?Russia to the north, Kazakhstan and Turkmenistan to the east, Iran to the south, and Azerbaijan to the west?hold some of the largest oil and gas reserves in the world. And together with neighboring Armenia, Georgia, Turkey, Ukraine, and Uzbekistan, they represent important economic, political, and strategic interests for the United States. To advance those interests, Washington should strengthen its policy toward the Caspian by giving the highest level of support to the cooperative development of regional energy reserves and pipelines. In particular, it should encourage the construction of multiple pipelines to ensure diverse and reliable transportation of Caspian energy to regional and international markets.
