In 2018, filmmaker Andreas Orth interviewed military experts from France, Germany, Russia and the US. He looked at images of a new generation of nuclear weapons, and even filmed in once top-secret former nuclear missile installations. Four years on, in the wake of Putin’s invasion of Ukraine, how do experts assess the situation? How great is the danger of nuclear weapons being used in the war against Ukraine? "The New Cold War – More Nuclear Weapons in Europe?" is a critical look at current nuclear armament and what it means for Europe.
