A Turning Point for Nuclear Deterrence: Shifting Global Security Architectures and Lessons from Ukraine
The global nuclear landscape is undergoing a significant shift as traditional arms control treaties, like New START, face expiration. The article discusses how the U.S. commitment to NATO is being questioned, potentially forcing Europe to rethink its security architecture. The war in Ukraine has reignited debates on nuclear deterrence, demonstrating that while nuclear threats exist, they do not always prevent conventional conflict. Meanwhile, major powers like China, Russia, and the U.S. are modernizing their arsenals. The 'taboo' on nuclear use is weakening as nations develop smaller, 'usable' tactical weapons, signaling a potential return to Cold War-era levels of nuclear tension.
