The White House condemned Russian President Vladimir Putin's comments on the potential use of nuclear weapons on Friday, stating that the United States has not made any changes to its nuclear posture in response to those remarks. This statement from the White House came after Putin said earlier on Friday that Russia could "theoretically" use nuclear weapons if there was a threat to its territorial integrity or existence, but that it does not need to do so. In response to questions from reporters aboard Air Force One, White House Deputy Press Secretary Olivia Dalton also affirmed the United States' commitment to NATO's principle of collective defense.
