U.S. President Joe Biden used a Tuesday speech at the United Nations General Assembly in New York to call on world leaders to continue to support Ukraine against Russia's "illegal war of conquest."
"Russia believes that the world will grow weary and allow it to brutalize Ukraine without consequence," Biden said.
"If we allow Ukraine to be carved up, is the independence of any nation secure? I'd respectfully suggest the answer is no. We must stand up to this naked aggression today to deter other would-be aggressors tomorrow," he said, to applause.
"Russia alone has the power to end this war immediately. Russia's price for peace is Ukraine's capitulation, Ukraine's territory and Ukraine's children."
Ukrainian President Volodymyr Zelenskyy is also set to speak and the event, where he could come face to face with top Russian officials.
Despite some calls for its removal, Russia is a permanent member of the UN and one of five permanent members of the U.N.'s Security Council.
