Nuclear War Risk Rises as Tension Mounts between Nuclear Superpowers over Ukraine

Feb 23, 2022 • Russian President Vladimir Putin's decision to order troops into the separatist-controlled areas of Ukraine has triggered a new wave of sanctions against Russia, amid fears the situation could spiral into an all-out war. We speak with Dr. Ira Helfand, former president of International Physicians for the Prevention of Nuclear War, who warns a war could lead to the use of nuclear weapons that would annihilate millions and cause total collapse of world ecosystems. "We have found it almost impossible to imagine, 30 years after the end of the Cold War, that there could be a nuclear war between the United States and Russia, but the crisis in Ukraine is putting exactly that possibility on the table again," says Helfand.
