Biden calls for more support for Ukraine

President Biden on Tuesday said the United Nations General Assembly meets "at an inflection point in history," and called for strengthened alliances while stressing that "no nation can meet the challenges of today alone." Biden, delivering his annual speech to leaders of the UN in New York City on Tuesday, addressed the United States' continued support for Ukraine against Russia's "naked aggression," the importance of denuclearization of the Korean peninsula and efforts to block Iran from nuclear proliferation; the competition between the United States and China; the climate crisis and more.
