Ukraine war: ‘Don’t. Don’t. Don’t’ – US President Biden warns Russia’s Putin against using nuclear or chemical weapons
- ‘You will change the face of war unlike anything since World War II’, said President Biden in a television interview to be aired on Sunday night
- Putin has warned Moscow would respond more forcefully if its troops were put under further pressure, raising concerns about use of nuclear weapons

US President Joe Biden urged Russian President Vladimir Putin to not use tactical nuclear or chemical weapons in the wake of setbacks in Ukraine, in a CBS News interview to air on Sunday.
Ukraine’s military drove back Russian forces in a lightning rout in the northeast of the country this week, putting Putin under pressure from nationalists at home to regain the initiative.
Putin has warned that Moscow would respond more forcefully if its troops were put under further pressure, raising concerns that he could at some point use unconventional means like small nuclear or chemical weapons.
Asked by a 60 Minutes reporter what he would say to Putin if he was considering using such weapons, Biden said: “Don’t. Don’t. Don’t. It would change the face of war unlike anything since World War Two,” in a clip of the interview released by CBS on Saturday.
Biden said the US response would be “consequential,” but declined to give detail. Russia “would become more of a pariah in the world than they ever have been,” Biden said. “Depending on the extent of what they do will determine what response would occur.”
Russian government officials have dismissed Western suggestions that Moscow would use tactical nuclear weapons in Ukraine, but it remains a worry for some in the West.
