As the world convulses in war and contentiousness, its leaders convene at the UN to figure it out

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.

“We are gathering in turbulent — even uncharted — waters,” Guterres said. He pointed to, among other specters, "our planet overheating, new technologies racing ahead without guardrails, inequalities widening by the hour.”

They gather for a better world, but can they build it?

Guterres said he will use the more than 150 one-on-one meetings he has with leaders and ministers to urge that they speak to each other, bridge divides, reduce risks and find solutions — to conflicts, to keep the planet from increased warming, to put guardrails on fast-expanding artificial intelligence, and to find funding for lagging U.N. goals for 2030 including ending poverty in all countries and ensuring quality education for every child.

He said leaders must make progress, not merely engage in “posturing and promises."

But U.N. watchers say that in a deeply polarized world, with no prospects of ceasefires in Gaza, Ukraine and Sudan, whether the high-level meeting makes any progress remains a big question mark.

Richard Gowan, U.N. director for the International Crisis Group, said he is confident three topics will dominate high-level week – U.S. President Donald Trump’s first appearance in his second term, the horrific situation in Gaza, and what’s next for the United Nations as it grapples with major funding and staff cuts, mainly due to the cutoff in U.S. payments to its regular and peacekeeping budgets.

Gowan said he expects the nearly two-year war in Gaza to be the central issue, as Israel launches a major offensive in Gaza City forcing thousands to flee and following a report by independent experts commissioned by the U.N. Human Rights Council that accused Israel of committing genocide in Gaza. Israel rejected the allegation, calling the report “distorted and false.”

Riyad Mansour, the Palestinian ambassador to the United Nations, has stressed that “Palestine is going to be the huge elephant in this session of the General Assembly.”

It will be front and center on Monday at a high-level meeting co-chaired by France and Saudi Arabia on implementing a two-state solution to the nearly eight-decade Israeli-Palestinian conflict. And the spotlight will be even brighter because the Trump administration refused to give a U.S. visa to Palestinian President Mahmoud Abbas to speak at that meeting and the General Assembly.

On Friday, the General Assembly overwhelmingly adopted a resolution enabling Abbas to speak by video — as it did in 2022 for Ukrainian President Volodymyr Zelenskyy following Russia's invasion. This year Zelenskyy will be attending in person, and the Security Council is expected to meet on Ukraine on Tuesday.

The assembly voted overwhelmingly earlier this month to support a two-state solution and urge Israel to commit to a Palestinian state. Hours before that vote, Israeli Prime Minister Benjamin Netanyahu said that “there will be no Palestinian state.”

More than 145 countries already recognize Palestine as a state, and Mansour told The Associated Press on Sunday that “it's going to be 10 more” announcing their recognition at Monday afternoon’s meeting. High-level week is also expected to see a Security Council meeting on Gaza, possibly Tuesday afternoon.

Lots of thorny issues are on the docket

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.

Gowan 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.

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 .

An event on Monday will commemorate 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.

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.”
