The US has issued a stark warning to Russia, saying that “decisive” actions and “catastrophic” consequences will follow if the Kremlin deploys nuclear weapons in its invasion of Ukraine.
“If Russia crosses this line, there will be catastrophic consequences for Russia. The United States will respond decisively,” National Security Adviser Jake Sullivan told NBC’s “Meet the Press” Sunday.
Sullivan declined to specify the potential US reaction, only saying: “In private channels we have spelled out in greater detail exactly what that would mean.”
