'Democracy will and must prevail' -Biden

"I believe that every ounce of my being that democracy will and must prevail. We must demonstrate that democracy can still deliver for our people," Biden said.

Biden told U.S. allies that they must stand firm against the challenges posed by China, Russia and Iran, saying Russia was seeking to weaken the transatlantic alliance and calling for a united front to counter what he called China's abusive economic practices.
