‘NATO Won't Be Divided’: Rattled Biden responds to Putin's nuclear warning

U.S. President Joe Biden is in a huddle after Russia put Nuclear Arms Treaty (START) on hold owing to Western weapons aid to Ukraine amid war. Speaking from Poland, hours after Russian President Vladimir Putin's state of the nation address, Biden has said that Ukraine 'stands strong' a year after Russia's invasion and that Moscow would never defeat it. "I can report: Kyiv stands strong, Kyiv stands proud, it stands tall and, most important, it stands free. When President Putin ordered his tanks to roll into Ukraine, he thought we would roll over. He was wrong," Biden said. Watch this video to find out how Biden is rallying NATO allies after Putin's nuclear warning.
