Recent and rapid changes in the world have led to a reexamination of a number of national policy issues. This report focuses on the issue of the current and projected U.S. dependence on strategic materials from southern African nations. The authors conclude that the United States is very dependent on two materials (chromium and cobalt) and somewhat dependent on three other materials (manganese, platinum group metals, and vanadium) obtained from southern African nations. The article also briefly discusses four hedging options against these dependencies: purchasing and stockpiling strategic materials, industrial incentives, research into alternative sources for these materials, and research into alternative materials.
