A World in Disarray: American Foreign Policy and the Crisis of the Old Order: Summary & Key Insights

After 1945, the world looked to the United States for stability, and we responded by building a system where alliances, institutions, and shared norms replaced the destructive chaos of global conflict. Out of devastation came design: NATO for security, Bretton Woods for economic coordination, the United Nations for diplomacy, and rules-based trade for prosperity. Each of these reflected a conviction that American leadership was indispensable but should be exercised in service of global public goods. The liberal order was far from perfect—it privileged stability over equality and sometimes imposed Western rules on non-Western realities—but it gave the world a mechanism to prevent major wars and to manage competition.

From my vantage point as a policy planner and later as an observer at the Council on Foreign Relations, I saw how this system worked best when American ideals were married to pragmatic strategy. What made it sustainable was not dominance but credibility—the sense that the United States would act predictably and within frameworks others helped design. But the conditions that created that world—clear victories, shared threats, and relative economic uniformity—began to dissipate over time. As memories of the war faded and new states emerged, consensus fractured. The postwar order, once sturdy, became increasingly brittle.

The fall of the Soviet Union was a moment of triumph that paradoxically sowed future uncertainty. For four decades, global policy had revolved around a bipolar logic: two superpowers, two ideologies, two competing systems. When the Soviet bloc collapsed, the United States found itself alone at the pinnacle—a condition I have described as the 'unipolar moment.' It was exhilarating but dangerous. Without an organizing rival, strategy turned instinctively outward. Humanitarian interventions, democratic expansion, and globalization surged forward, often without sufficient grounding in local realities.

In those years, the notion took hold that history itself had ended—that liberal democracy and open markets would spread inexorably. But unipolarity is not permanence; it is a transition. Other powers began to reassert themselves, and globalization accelerated both integration and imbalance. The euphoria of victory masked the fact that the institutions built for Cold War stability were ill-equipped for an era of asymmetric threats and diffused power. The challenge was not victory but adjustment—to find a new equilibrium after the certainties of bipolarity had vanished.
