Asia & the Pacific

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

According to the "Madman Theory" outlined by Daniel Ellsberg and Thomas C. Schelling, and embraced by Presidents Richard Nixon and Donald Trump, being perceived as mad can help make seemingly incredible threats—such as starting a nuclear war—more credible. However, recent research has largely concluded that the Madman Theory does not work. 

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

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.

The Icelandic Ministry for Foreign Affairs recently published an extensive report with a detailed analysis on the current relationship between Greenland and Iceland with 99 recommendations on how to strengthen their co-operation. Halla Hrund Logadóttir moderated the discussion.

As the world commemorates the 70th anniversary of the start of the Korean War, the Center for the National Interest's Korean Studies team decided to ask dozens of the world's top experts a simple question: Do you believe that the Korean War will finally come to an end before its next major anniversary in 2025? Joseph Nye provides his answer to that question.
