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.

  • Miles M. Evers

| Oct. 02, 2023

Joseph Nye writes that if the United States maintains its alliances, invests in itself, and avoids unnecessary provocations, it can reduce the probability of falling into either a cold war or a hot war with China.
