When the controversy over the Siberian natural gas pipeline erupted in 1982, it was not the first time that the issue of East-West energy trade had brought the United States into conflict with its Western European allies. It was, however, the first time that the United States lacked the leverage necessary to change its allies' policies. In addition American political opposition more closely resembled the politics of the 1980 grain embargo than the anti-energy trade consensus of earlier decades. How are these changes to be explained? What have their consequences been for American economic coercive power against the Soviet Union? Bruce Jentleson addresses these and other crucial questions in this comprehensive and incisive study.
