In his speech, Biden urged democracies around the world to unify against Russia and commit to a historic battle against authoritarian aggression. “In this battle, we need to be clear-eyed,” he said. “We need to steel ourselves for the long fight ahead. A dictator, bent on rebuilding an empire, will never erase the people’s love for liberty,” Biden said at the end of a sweeping speech in Poland. “Ukraine will never be a victory for Russia, for free people refuse to live in a world of hopelessness and darkness. For God’s sake, this man cannot remain in power,” Biden said, calling for regime change in Russia.
