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. 

David Kearn argues that the idea that the first use of nuclear weapons since 1945 would be by the United States in the defense of Taiwan against a conventional Chinese invasion would have significant, negative, and long-lasting, diplomatic ramifications. It is difficult to fathom the myriad potential consequences, but U.S. nuclear weapon use would almost certainly shatter the non-proliferation regime as a functioning entity, incentivize states (including China) to acquire or improve their existing nuclear arsenal, and damage America's standing globally.
