Why WWII Mobilization Won't Repeat

The Hoover History Lab and its Applied History Working Group in close partnership with the Global Policy and Strategy Initiative held The Arsenal of Democracy Technology, Industry, and Deterrence in an Age of Hard Choices on Thursday, November 20, 2025, from 4:00 PM - 5:15 PM PT.

The event featured the authors Eyck Freymann, Hoover Fellow, and Harry Halem, Senior Fellow at Yorktown Institute, in conversation with Stephen Kotkin, Kleinheinz Family Senior Fellow.

The US military stands at a moment of profound risk and uncertainty. China and its authoritarian partners have pulled far ahead in defense industrial capacity. Meanwhile, emerging technologies are reshaping the character of air and naval warfare and putting key elements of the US force at risk. To prevent a devastating war with China, America must rally its allies to build a new arsenal of democracy. But achieving this goal swiftly and affordably involves hard choices.

The Arsenal of Democracy is the first book to integrate military strategy, industrial capacity, and budget realities into a comprehensive deterrence framework. While other books explain why deterrence matters, this book provides the detailed roadmap for how America can actually sustain deterrence through the 2030s—requiring a whole-of-nation effort with coordinated action across Congress, industry, and allied governments.

Rapidly maturing technologies are already reshaping the battlefield: unmanned systems on air, land, sea, and undersea; advanced electronic warfare; space-based sensing; and more. Yet China’s industrial strengths could give it advantages in a protracted conflict. The United States and its allies must both revitalize their industrial bases to achieve necessary production scale and adapt existing platforms to integrate new high-tech tools.
