Uppsala University – Reducing the Risks of Nuclear Weapons

After a long period of post-Cold War stability, the risks posed by nuclear weapons are increasing sharply.  This is marked by the invasion of Ukraine, a nuclear generation of Russian nuclear weapons, expansion of China’s nuclear arsenal and tensions over Taiwan, missile testing by North Korea and uranium enrichment by Iran, and a major nuclear modernization program in the United States, with calls for substantial increases to respond to Russia and China.  Physicists played an important role in nuclear debates during the Cold War; they can play an important role again in this new period of increased nuclear risk.
