What if the next world war does not begin with missiles, mushroom clouds, or tanks crossing a border?

What if it begins when ports freeze, power grids fail, payment systems stall, supply chains snap, and nobody can prove whether it was an accident, a system error, or an attack?

In World War III Has Already Begun, Haijian Xing argues that modern conflict is moving beyond the battlefield and into the hidden architecture of civilization itself. The real targets are no longer only armies and territory, but permissions, models, infrastructure, incentives, expectations, and the fragile systems that make modern life possible.

Blending systems thinking, technology, geopolitics, finance, infrastructure risk, and cultural storytelling, this book explores how warfare changes when the most powerful attacks no longer look like war at all. From the collapse of bridges and power grids to digital dependencies, cascading failures, strategic topology, war debt, and the weaponization of expectation, Xing shows how advanced societies can be pushed toward crisis without a single traditional invasion.

Written for general readers but packed with deep ideas for those who want to look further, this is a book about the new logic of power in an age of AI, networked systems, and invisible leverage.

This is not just a book about war. It is a book about how modern civilization breaks — and how to recognize it before it does.
