In "To Provide and Maintain a Navy," Dr. Henry J. "Jerry" Hendrix embarks on a profound exploration of the sea's pivotal role in shaping the contours of global power and prosperity. Beyond the simplistic tally of naval assets, Hendrix delves into the philosophical underpinnings of Mare Liberum, or the freedom of the seas, tracing its influence from the genesis of Western thought through to the establishment of a rules-based international order that has governed the high seas for centuries. This sweeping narrative reveals how the open sea, acting as the lifeblood of commerce, has been instrumental in elevating global living standards, weaving a compelling link between maritime dominance and economic vitality. As the narrative unfolds, Hendrix presents a meticulous analysis of the shifting tides of naval power and their profound impact on historical conflicts and the maintenance of peace. The United States Navy, emerging as a preeminent force post-World War II, has played a crucial role in securing a period of unparalleled tranquility on the world's oceans. However, the contemporary era presents new challenges, with rising powers like China and Russia seeking to redefine maritime sovereignty and disrupt five centuries of naval tradition. Hendrix argues persuasively for a reinvigorated American seapower strategy, emphasizing the need not only for numerical strength but also for a robust industrial base capable of sustaining naval supremacy. "To Provide and Maintain a Navy" stands as a seminal work, offering deep insights into the strategic imperatives facing the United States as it navigates the turbulent waters of great power competition.
