Current global trends point to a highly complex future security environment characterized by budget-induced modernization challenges, persistent conflicts exacerbated by climate change, and revisionism and breaches of international norms by increasingly powerful peer and near-peer nation-states. Republican Congressman and Chair of the House Armed Services Committee Mac Thornberry and Dr. Andrew Krepinevich Jr., President Emeritus at the Center for Strategic and Budgetary Assessments, recently warned that “the United States confronts mounting threats with increasingly constrained resources . . . and growing uncertainty both at home and abroad.”1
These challenges demand effective strategic leaders across the armed services.2 History teaches us that challenges are best met by a combination of leadership styles. The nation needs reformers, thinkers, and warriors. Examining these leadership archetypes as exemplified by past Navy leaders can help today’s leaders address the security issues facing our nation.
