Watched by the world, President Donald Trump returns to the United Nations on Tuesday (September 23, 2025) to deliver a wide-ranging address on his second-term foreign policy achievements and lament that “globalist institutions have significantly decayed the world order,” according to the White House.
World leaders will be listening closely to his remarks at the U.N. General Assembly as Mr. Trump has already moved quickly to diminish U.S. support for the world body in his first eight months in office. Even in his first term, he was no fan of the flavour of multilateralism that the United Nations espouses.
After his latest inauguration, he issued a first-day executive order withdrawing the U.S. from the World Health Organisation. That was followed by his move to end U.S. participation in the U.N. Human Rights Council, and ordering up a review of U.S. membership in hundreds of intergovernmental organisations aimed at determining whether they align with the priorities of his “America First” agenda.
