Live Nuclear Tests May Resume Within the Next 10–15 YearsA Russian nuclear expert warns that a generational shift in leadership within nuclear weapons complexes could bring the world closer to renewed nuclear testing. “We are closer to this situation than ever since the last North Korean nuclear tests. Experts in U.S. national laboratories, in Russia’s nuclear weapons complex, and in Europe built their careers on guaranteeing political leadership that even without tests the arsenal remains secure. We have the technologies and extremely expensive machines that allow us to confirm the reliability of nuclear warheads without live trials. The transfer of responsibility to a new generation of leaders who lack the same first-hand experience may increase pressure for live nuclear testing.
