A decade after the cold war ended, policy makers and academics foresaw a new era of peace and prosperity, an era in which democracy and open trade would herald the "end of history." The terrorist attacks of September 11, 2001, sadly shattered these idyllic illusions, and John Mearsheimer's masterful new book explains why these harmonious visions remain utopian.

To understand world politics, you need to understand how states think. Are states rational? Much of international relations theory assumes that they are. But many scholars believe that political leaders rarely act rationally. The issue is crucial for both the study and practice of international politics. John J. Mearsheimer and Sebastian Rosato argue that rational decisions in international politics rest on credible theories about how the world works and emerge from deliberative decision‑making processes.

America is in a new Cold War with Russia even more dangerous than the one the world barely survived in the 20th century. All of this is exacerbated by Washington’s war-like demonizing of the Kremlin leadership and by Russiagate’s unprecedented allegations. US mainstream media accounts are highly selective and seriously misleading. American “disinformation”, not only Russian, is a growing peril.

China and America are world powers without serious rivals. They eye each other warily across the Pacific; they communicate poorly; there seems little natural empathy. A massive geopolitical contest has begun. America prizes freedom; China values freedom from chaos. America values strategic decisiveness; China values patience.America is becoming society of lasting inequality; China a meritocracy. America has abandoned multilateralism; China welcomes it.

The relationship between the US and China, the world’s two superpowers, is peculiarly volatile. Their militaries play a dangerous game of chicken, corporations steal intellectual property, intelligence satellites peer, and AI technicians plot. The capacity for either country to cross a fatal line grows daily. Kevin Rudd, a former Australian prime minister who has studied, lived in, and worked with China for more than forty years, is one of the very few people who can offer real insight into the mindsets of the leadership whose judgment will determine if a war will be fought.
