Julianne Smith, the US's ambassador to NATO, called Biden's surprising comments a "principled human reaction," made after he spent the day seeing the firsthand tragedies of war, when he visited with hundreds of Ukranian refugees, in a Sunday interview with CNN's Dana Bash on "State of the Union."
"He went to the National Stadium in Warsaw and literally met with hundreds of Ukrainians. He heard their heroic stories as they were fleeing Ukraine in the wake of Russia's brutal war in Ukraine. In the moment, I think that was a principled human reaction to the stories that he had heard that day."
Still, Smith said, the "US does not have a policy of regime change in Russia, full stop."
