Environment & Climate Change

Stephen Walt advises that in order to prepare students of public policy schools for a rapidly changing world, faculty should teach historical cases where the prevailing theories led to bad policy choices, and where new ones had to be devised to address a novel set of circumstances. 

Climate disasters shape the trajectory of internal conflicts in states highly vulnerable to changes in conflict dynamics. Conflict after a climate disaster escalates when the disaster induces shifts in relative power that enable one side to increase its military efforts. But when one actor is weakened by the disaster and the other lacks the capability to exploit that weakness, conflict intensity declines.

Joseph S. Nye argues that history shows that globalization is largely driven by technological changes that reduce the importance of distance, and that will not change.

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

Stephen M. Walt describes a "gnawing fear that we are living through a series of disruptions that are overwhelming our collective ability to respond." What does this mean for public confidence in the entire political system, and is there any cause for optimism?

Stephen Walt argues that what 9/11 means to future generations depends less on what actually occurred on that day or on how the United States and others responded and more on what the United States and others do from this day forward. 

During the Cold War, US grand strategy focused on containing the power of the Soviet Union. China's rise now requires America and its allies to develop a strategy that seeks not total victory over an existential threat, but rather managed competition that allows for both cooperation and rivalry within a rules-based system.

At one point in human history, water’s importance in war went beyond bearing convoys, hiding submarines, and slaking soldiers’ thirst. Water was often itself a weapon. In areas where it was scarce, armies took action to make it scarcer to force besieged enemy cities to capitulate, and in areas where it was abundant, combatants destroyed dams and watched the resulting floods carry their adversaries away. Today, however, most combatants recoil at the use of water as a weapon, and only the most depraved deploy it.

Since the end of World War II, nation-states in international conflict have made concerted efforts to restrain the weaponization of water. Distinct from realist and rationalist explanations, the historical record reveals the rise of an international normative inhibition—a “water taboo”—on using water as a weapon.

Joel Clement writes that the federal government must allow community voices to drive infrastructure investment  and conservation in the North.
