The history of wars caused by misjudgments, from Napoleon’s invasion of Russia to America’s invasion of Iraq, reveals that leaders relied on cognitive models that were seriously at odds with objective reality. Blinders, Blunders, and Wars analyzes eight historical examples of strategic blunders regarding war and peace and four examples of decisions that turned out well, and then applies those lessons to the current Sino-American case.

Mounting costs, risks, and public misgivings of waging war are raising the importance of U.S. power to coerce (P2C). The best P2C options are financial sanctions, support for nonviolent political opposition to hostile regimes, and offensive cyber operations. The state against which coercion is most difficult and risky is China, which also happens to pose the strongest challenge to U.S. military options in a vital region.

Looking to the 2030–2040 time frame, U.S. policy and military strategy will need to strike a balance among maintaining a cooperative relationship with China, deterring Chinese aggression in regional disputes, and preparing for the possibility that China could become more assertive. The U.S. Army will have an important role to play in preparing for these developments and for protecting and furthering U.S. interests in the region.

In the event of a Sino-U.S. war, intense conventional counterforce attacks could inflict heavy losses and costs on both sides, so leaders need options to contain and terminate fighting. As it takes steps to reduce the likelihood of war with China, the United States must prepare for one by reducing force vulnerabilities, increasing counter–anti-access and area-denial capabilities, and using economic and international effects to its advantage.
