🔴LIVE: United Nations General Assembly

President Donald Trump is expected to speak at the U.N. General Assembly on Tuesday in New York around 9:45 a.m. ET.

The United Nations, which emerged from World War II’s rubble on the premise that nations would work together to tackle political, social and financial issues, is in crisis itself. As Secretary-General Antonio Guterres said last week: "International cooperation is straining under pressures unseen in our lifetimes."

Yet the annual high-level gathering at the U.N. General Assembly will bring presidents, prime ministers and monarchs from about 150 of the 193 U.N. member nations to U.N. headquarters. The secretary-general says it is an opportunity that can’t be missed — even in the most challenging of moments.

The high-level meeting starts Tuesday morning in the vast General Assembly chamber. Trump will speak that day shortly after Guterres’ opening "state of the world" speech.

Richard Gowan, U.N. director for the International Crisis Group, said there is "hope" that Trump will come in a positive mood, touting the international accomplishments that the president says merit the Nobel Peace Prize. Also on the docket: Trump’s financial approach to the larger world. "Obviously, most leaders are going to be focusing on what he has to say about tariffs," Gowan said, but also about Russia and China.

Other speakers to watch are interim Syrian President Ahmad al-Sharaa, making his debut on the international stage following the ouster of former strongman Bashar Assad in December, and Iranian President Masoud Pezeshkian.

The Iranian leader will be in New York days after the Security Council decided not to permanently lift U.N. sanctions on his country over its escalating nuclear program, but it gave Tehran and key European powers France, Germany and the United Kingdom until midnight Sept. 27 to agree to a delay. That’s when the sanctions will automatically "snapback" unless a deal is reached.

The high-level week will also see numerous meetings on tackling climate change; on the more than two-year war in Sudan started by rival military and paramilitary generals that has sparked the world’s worst displacement crisis; on Somalia, which is home to the extremist group Al-Shabab; and on Haiti, where gangs control over 90% of the capital and have expanded into the countryside.

Immediately after Monday’s 80th-anniversary commemoration, the assembly marked the 30th anniversary of the Beijing women’s conference, which adopted a platform to achieve gender equality. The United Nations says that goal is growing more distant and Guterres has said it is 300 years away on the current track.

Sima Bahous, executive director of UN Women, warned that on the current path, 351 million women and girls will live in extreme poverty in 2030 — and "676 million women and girls live within reach of deadly conflict." That’s the highest since the 1990s.

One of Guterres’ major aims this year: to generate support for his plans to reform the United Nations and make it more responsive to the world as it is in 2025. Because of funding cuts by the U.S. and others, the U.N. announced last week that its regular operating budget for 2026 needs to be cut by 15% to $3.2 billion along with a 19% cut in that budget’s staff positions — 2,681 posts.

Gowan said he doesn’t see the United States or other countries running away from the United Nations. But he stressed that it is going through "an extraordinarily difficult period" and will have to shrink and change.

"The U.N.’s resonance on peace and security issues is unquestionably not what it was," he said, "but I think that the organization will continue to muddle through."
