This book makes a blunt claim: the United States holds a decisive lead over China in economic power. That lead rests not only on raw Gross Domestic Product (GDP), but on control of firms, technologies, and global production networks. Vagle & Brooks argue that economic power is lopsided and it tilts sharply toward Washington. Their case rests on two points: First, the United States and its allies dominate global high-tech industries. This is not necessarily measured by output or trade volume, but by profits and command over multinational firms. The numbers are striking. US firms generate over half of all profits in key sectors. Together with allies, they account for 84% of high-tech global profits. Conversely, Chinese firms generate 6%. Second, the book re-evaluates China's capacity. Official growth rates and GDP figures are misleading, inflated by political incentives and statistical distortions. Adjusted for misreporting, China’s economy may be closer to half the size of the US. The heart of the book is a set of wartime economic scenarios. In each scenario, the authors model the effects of a coordinated Western cutoff of trade and investment with China. In the short run, China's losses are 5 to 11 times greater than America's. In the long run, the US and allies recover. In contrast, China’s growth slows permanently. The central claim by the authors is thus that interdependence is not symmetric, and the US has far more leverage than it has used. Command of Commerce offers a useful corrective to declinist narratives. It is a sharp, data-rich, and policy-relevant study of how economic power actually works, and why the US is still the commanding force in world politics.
