World Leaders Won’t Gather for the U.N. General Assembly for First Time in Its 75-Year History. The president of the U.N. General Assembly said Monday that world leaders will not be coming to New York for their annual gathering in late September for the first time in the 75-year history of the United Nations because of the COVID-19 pandemic.
