Blending history, strategy, and policy, this analysis presents a comprehensive U.S. approach to countering the coordinated threat posed by China, Russia, and Iran. It outlines how America can exploit their shared weaknesses and secure strategic dominance across Eurasia through military preparedness, alliance-building, and coherent grand strategy.  This innovative work fundamentally redefines how the United States should approach grand strategy when confronting the “New Axis” of China, Russia, and Iran by revealing their critical weaknesses—internal pressures, lack of cohesive coordination, and short-term thinking—and presenting a unique opportunity for America to turn the tide.  Authors Seth Cropsey and Harry Halem meticulously explain why Eurasia, the world’s largest landmass and historically the epicenter of power, remains strategically paramount. Structured into four compelling sections, Breaking the New Axis guides readers through the intricacies of geopolitics, strategy, and large-scale combat: exploring Eurasian strategic thought, dissecting threats from revisionist powers, examining defense technology's role, and demanding U.S. strategic coherence. The book offers actionable solutions, with a detailed roadmap for preparing the United States to deter and, if necessary, win a Eurasian-wide war: revitalizing the defense industrial base, reorganizing command-and-control for combat, leveraging strategic intelligence, and strengthening alliances across Europe, the Middle East, and Asia.  Engaging, deeply insightful, and unequivocally urgent, Breaking the New Axis is an indispensable read for policymakers, strategists, and anyone invested in global stability.
