The United States is the world's preeminent military power due in large part to its techlogical superiority. This lead in invative techlogy supporting national security also includes advances in new and green energy applications. A common ingredient enabling the production of many of these applications is a group of minerals kwn as rare earth elements (REEs). As the American military and industrial sectors continue their move toward increased reliance on miniaturized high-performance electronics and strive to adopt more energy-efficient techlogies, there are concerns that the US may trade its reliance on Middle East oil for dependence on REEs from China. This paper will illustrate how REEs have become a deeply ingrained need throughout the American ecomy and, in particular, how rare-earth magnets are w indispensible to the defense industry. It will explore how the United States should react to a threat to its lead in the techlogical invation of military applications using permanent magnets.
