The White House said on March 13 it had seen no indications that Moscow is ready to use a nuclear weapon in Ukraine after President Vladimir Putin said he was ready to deploy them if Russia's sovereignty was threatened. "We have not seen any reasons to adjust our own nuclear posture, nor any indication that Russia is preparing to use a nuclear weapon in Ukraine," spokeswoman Karine Jean-Pierre said. Putin appeared to be "restating Russia's nuclear doctrine" after he was asked about using the weapons. Jean-Pierre added that “Russia's nuclear rhetoric” has been "reckless" throughout its full-scale invasion of Ukraine.
