This volume poses two central questions. What does energy security mean now that energy supply is increasingly determined by market forces? What are the most likely circumstances under which the United States may have to apply diplomatic and military pressure to ensure orderly world energy markets? The essays examine the areas of the energy market that are of most concern to American national security. They also consider energy prospects in key countries from their security point of view, either because the countries are in volatile regions such as the Persian Gulf or because they are major military as well as energy powers such as Russia.The contributors are Phil Sharp, John Lyman, Vladimir Likhachev, Milton Russell, Fereidun Fesharaki, Eliyahu Kanovsky, Guy Caruso, Robert Eynon, Thomas Cochran, Hill G.
