"This cannot be sustained," Trump told the UN General Assembly on Tuesday, calling the crisis of uncontrolled migration "the number one political issue of our time." Your countries are being ruined," he said, accusing the UN of funding an "assault on Western countries and their borders," citing the $372 million spent by the organization in 2024 on supporting an estimated 624,000 people migrating to the US. He went on to claim that Europe is in "serious trouble" and has been "invaded" by an unprecedented "force of illegal aliens" that is "pouring" into the continent. "You're doing it because you want to be nice," Trump said, addressing his European counterparts. "You want to be politically correct, and you're destroying your heritage," he claimed, calling for an end to "the failed experiment of open borders."
