Prof. John Mearsheimer argues that the world is entering a new era of great-power rivalry, warning that “we’re definitely going to have a Cold War.” He points to rising tensions between the United States, China, and Russia as evidence that the international system is shifting into a more confrontational, multipolar structure. According to Mearsheimer, this new Cold War is not just political or military, but also deeply economic, reshaping global investment, strategy, and power relations in ways not seen during the original US–Soviet rivalry.
