A leading expert explains three circumstances under which Russia might use nuclear weapons. James Acton of the Carnegie Endowment for International Peace breaks down Vladimir Putin’s latest threat to use weapons of mass destruction in the Ukraine war, what it says about the state of the conflict and how dangerous things could get.
In an interview with DW’s Richard Walker, Acton warns, “Once the nuclear threshold has been crossed, there is no guarantee you're going to be able to stop short of the end of civilization.” And he explains what the international community should do to reduce the risks.
