President Joe Biden surprised his top advisers along with everyone else when, at a fundraising event, he referred to “Armageddon” in the Ukraine war: Russia’s possible use of a nuclear weapon. Though United States officials were quick to stress that they knew of no imminent threat by Russia, Biden’s remark underscored recent reports suggesting deepening U.S. concern about what Putin might do as Russian forces retreat in eastern and southern Ukraine.
The remark also was in response to Putin’s increasingly frequent allusions to nuclear weapons, such as on Sept. 21, when he said: “If the territorial integrity of our country is threatened, we will without doubt use all available means to protect Russia and our people. This is not a bluff.”
