A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war.

| Winter 2023/24

The non-Soviet members of the Warsaw Pact contributed to the end of the Cold War along with the superpowers. These Eastern European states recognized that their relationship with the Soviet Union would impede their success in the post–Cold War world, so they ended the Pact.

Narratives and War: Explaining the Length and End of U.S. Military Operations in Afghanistan

    Author:
  • C. William Walldorf Jr.
| Summer 2022

A new theory of war duration suggests that strategic narratives explain why the U.S. war in Afghanistan endured and ended. A robust anti-terrorism narrative generated audience costs for presidential inaction. As the narrative weakened, these costs declined, and the war ended.

| Mar. 23, 2022

Along with concerns over the possible deployment of tactical nuclear weapons, the Biden administration is now warning that the Russian military may launch a chemical weapons attack in Ukraine. Russia has used chemical weapons during past conflicts, notably in Chechnya and Syria, in violation of international law. Russian officials denied Biden’s accusation during a U.N. Security Council meeting Tuesday.

The End of Cyber-Anarchy?

| January/February 2022

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.
