In 1941 and 1942, Walter Levy wrote about the effect of oil on Nazi and Japanese strategy. In 1981, he wrote in this journal about the oil agenda of the next decade. In between, he wrote much about the critical significance of oil in our time. This selection of papers, each skillfully introduced and set in place by Melvin Conant, shows how regularly Mr. Levy forecast the importance of international cooperation, the inadequacies of U.S. policy, the consequences of reliance on the Middle East, and the unsolved problems of finding the right relation between governments and oil companies in the pursuit of the public interest. Without wishing Mr. Levy to stop looking ahead, one hopes that the publication of this body of work will lead him to look back as well, to explain more fully the developments to which he was so close.
