News Investigators/ U.S. President Donald Trump is set to address the UN General Assembly on Tuesday as world leaders grapple with crises from Gaza to Ukraine. Many question whether the United States, with its “America First” foreign policy, is still prepared to play a leadership role in global affairs. Guterres and Trump are expected to meet formally for the first time since Trump returned to office in January. Israeli Prime Minister Benjamin Netanyahu is due the address the General Assembly on Friday. Ukrainian President Volodymyr Zelenskiy and Russian Foreign Minister Sergei Lavrov will also address the General Assembly.
