ABSTRACT
This article (click image to download) examines the deeper past of the AUKUS agreement on submarines and defense technology between the United States, United Kingdom, and Australia by examining the period of naval cooperation immediately before the First World War. It argues that the key puzzles raised by AUKUS—the challenge of shifts to multipolarity, of sharing military technology, and of cooperating amidst questions of sovereignty and war—are far from new and were raging in that moment as well. It calls for rethinking present challenges not just in terms of their unexpectedly lengthy past, but in light of the subsequent wars of the twentieth century.
