Chip War: The Fight for the World's Most Critical Technology

Author: Chris Miller

In many classical accounts of international relations, energy resources, military capabilities, and geographic position have traditionally been regarded as the primary foundations of national power. In Chip War, Chris Miller argues that one additional element must now be added to this list in order to understand the contemporary world: semiconductors. In his view, computer chips have become the fundamental infrastructure underpinning the digital economy, advanced technologies, and the military capabilities of states. Consequently, competition over semiconductors has emerged as one of the most significant arenas of geopolitical rivalry in the twenty-first century.

The book begins with the historical development of the semiconductor industry. Miller explains how scientific research after World War II, combined with the military demands of the Cold War, led to the invention of the transistor and later the integrated circuit. In his narrative, the semiconductor industry was never merely a commercial enterprise; rather, it developed through a deep connection with strategic, security, and military competition. The advancement of missile guidance systems, telecommunications equipment, and advanced computing technologies transformed the U.S. government into one of the industry’s most important supporters.

A significant portion of the book examines how the United States established its early dominance over the semiconductor industry. The emergence of companies such as Fairchild Semiconductor and Intel, alongside a generation of entrepreneurs and engineers who later shaped Silicon Valley, laid the foundation for America’s technological superiority. However, this dominance was not permanent. Miller provides a detailed account of how Japan emerged as a formidable competitor during the 1970s and 1980s, capturing a substantial share of the global semiconductor memory market.

One of the most compelling sections of the book explores the rise of Taiwan and the emergence of Taiwan Semiconductor Manufacturing Company (TSMC). Miller demonstrates that the most significant transformation in the semiconductor industry did not occur in chip design, but rather in the business model of chip manufacturing. TSMC, by focusing exclusively on production, created what is now known as the “foundry” model—a system that enabled chip-design companies to concentrate on innovation and architecture without investing billions of dollars in their own fabrication facilities. This transformation reshaped the entire structure of the industry and turned Taiwan into one of the most critical nodes in the global technology supply chain.

From Miller’s perspective, the significance of semiconductors extends far beyond their economic value. Nearly every advanced technology today—from smartphones and data centers to weapons systems, satellites, artificial intelligence, and telecommunications infrastructure—depends on semiconductor technology. As a result, control over advanced chip-manufacturing capabilities has become a strategic issue. In a world where military and economic power are increasingly dependent on technological capabilities, access to the most advanced semiconductors can provide a decisive advantage.

In the second half of the book, the central focus shifts toward the technological rivalry between the United States and China. Miller explains why Beijing has invested heavily in developing a domestic semiconductor industry and why Washington has sought to restrict China’s access to advanced chip-manufacturing technologies. From this perspective, the chip war is not merely an industrial competition; rather, it represents a broader struggle over the future structure of global power.

Another major strength of the book is its explanation of the complexity of semiconductor supply chains. Unlike many traditional industries, no single country is capable of independently producing the world’s most advanced chips. Chip design may take place in the United States, critical manufacturing equipment may be produced in Europe, raw materials may be sourced from multiple countries, and final fabrication may occur in Taiwan or South Korea. This interdependence makes the semiconductor industry a remarkable example of technological globalization. At the same time, these dependencies have created new vulnerabilities that governments around the world are increasingly concerned about.

The central value of Chip War lies in its ability to move technology beyond a purely technical framework and place it at the heart of global politics. Miller demonstrates that understanding great-power competition is increasingly impossible without understanding the structure of the semiconductor industry. From this perspective, semiconductors occupy a role in today’s global politics similar to the role played by oil during much of the twentieth century.

For researchers in international relations, international political economy, security studies, technology policy, and those interested in U.S.-China competition, Chip War is an essential work. The book does not merely tell the history of an industry; it explains why the future of the global economy, international security, and even the balance of power among states depends to a significant extent on control over a technology that is manufactured on a microscopic scale but carries consequences of global significance.
