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.

Today’s economic crisis leaves us with an unsettling and perplexing regret. Why weren’t financial portfolios already adjusted for risks that stem from health events such as pandemics? After all, financial portfolios are adjusted for liquidity risks, market risks, credit risks, and even operational and political risks.

Columbia University Professor Scott Barrett assessed the massive global efforts underway to address COVID-19 and the potential impacts of the pandemic on our lives in the future in a special episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.

How do presidents incorporate morality into decisions involving the national interest? Moral considerations explain why Truman, who authorized the use of nuclear weapons in Japan during World War II, later refused General MacArthur's request to use them in China during the Korean War. What is contextual intelligence, and how does it explain why Bush 41 is ranked first in foreign policy, but Bush 43 is found wanting? Is it possible for a president to lie in the service of the public interest? In this episode, Professor Joseph S. Nye considers these questions as he explores the role of morality in presidential decision-making from FDR to Trump.
