When President Donald Trump made his United Nations debut a year ago, addressing the general assembly for the first time, he was determined to make waves.
And, of course, he did.
The president, by then eight months into the role, launched into a hair-raising tirade that shook the usually-staid chamber. He began by trumpeting his own domestic economic policies, before switching to give his take on world affairs. Kim Jong-un was labelled a suicidal “rocket man”, whose “depraved” country Mr Trump may decide to “totally destroy”. The Iran nuclear deal was an “embarrassment”.
On Tuesday Mr Trump is back, speaking shortly after 9am in what will, unsurprisingly, be one of the most closely-watched moments of the annual jamboree.
“Last year we started UNGA and it was trying to figure what the US presence was going to be,” said Nikki Haley, the US ambassador to the UN, on Monday. “This year, we’re here with a bang.”
Mr Trump’s “America First” rhetoric raised eyebrows last year, with critics seeing it as a disturbingly isolationist and unilateral message – a sharp, deliberate contrast to the globalist view of Barack Obama.
“I will always put America first, just like you, as the leaders of your countries, will always, and should always, put your countries first,” said Mr Trump.
It’s a message he intends to hammer home again this year.
Mrs Haley noted, ahead of Tuesday’s speech, that “he wants to talk about protecting US sovereignty.”
She added: “It’s not saying multilateralism can’t work. It is saying sovereignty is a priority over all of that.”
Mike Pompeo, the secretary of state, agreed, saying on Monday: “Whether it’s security issues, economic issues, human rights, or anything else, the president is asking for countries to exert their sovereignty to solve challenges and listening to what America can do to help.”
Equally, Mr Trump is likely to use his speech once again to trumpet his own domestic policies.
Last year he surprised many by opening with a recap of his successes, boasting how well the US stock market was doing, and how the US unemployment rate was falling.
Expect more of the same.
His diehard supporters may not pay attention to what Mr Trump himself derided, as president-elect, as “just a club for people to get together, talk and have a good time” – but Mr Trump is never one to miss an opportunity to shout about his own successes.
“Our economy is the envy, right now, of the world,” said Mr Trump on Monday, ahead of his talks with South Korean president Moon Jae-in.
“We are the fastest-growing economy in the world.”
Since Mr Trump took office, the nation’s gross domestic product has grown an average of 2.7 per cent per quarter, and unemployment is at a generational low. Business is booming, and the stock market is soaring. He will want everyone to know.
He is also certain to return to the topic of Iran – especially given that it’s his first UN speech since pulling the US out of the nuclear agreement, in May.
“You can bet the president will have well-deserved strong words for the Iranian regime, which is among the worst of violators of UN Security Council resolutions, if not the absolute worst in the world,” said Mr Pompeo on Monday.
“He’ll call on every country to join our pressure campaign in order to thwart Iran’s global torrent of destructive activity.”
It’s not a position that has received universal support in the US. Ahead of the general assembly, a bipartisan group of national security leaders, including Madeleine Albright, the former secretary of state, and James Clapper, the former director of national intelligence, strongly criticised Mr Trump’s Iran strategy in a statement issued on Sunday.
“The Trump administration’s Iran strategy is to assert maximum economic, political and military pressure to change Iran’s behaviour and threaten, if not cause, collapse of the regime,” they wrote.
“But since it has not undertaken diplomatic engagement on any of its twelve demands on Iran, the administration has left Iran the option of either capitulation or war.”
Mr Trump will also likely preview the Security Council meeting that he is chairing on Wednesday morning – an eagerly-watched gathering, not least to see how the freewheeling president copes with hosting a tightly-scripted diplomatic dance.
Watch closely to see how Mr Trump describes that Security Council meeting.
His aides have been trying to explain that the meeting needs to be about a broad range of issues, including Iran: if it is just about Iran, the Iranian leader, Hassan Rouhani, can have a seat at the table – a scenario US diplomats are keen to avoid.
The state department has since been at pains to describe the meeting as being about non-proliferation of nuclear weapons, and instability in the Middle East in general.
On September 7, the US mission to the UN issued a statement saying the meeting would focus on a “broader range of issues,” including the “proliferation of weapons of mass destruction” in addition to Iran’s destabilising activities.
Yet on Friday, Mr Trump tweeted: “I will Chair the United Nations Security Council meeting on Iran next week!”
Furthermore, Theresa May, Emmanuel Macron and Sergey Lavrov, the Russian foreign minister, all plan to attend the meeting – meaning that fireworks could ensue if Mr Trump steers the meeting towards open condemnation of the nuclear deal. US diplomats are deeply worried about a possible confrontation with key allies.
“Trump risked a collision with the UK and France over Iran at the UN,” said Richard Gowan, a senior fellow at the United Nations University, a global affairs think tank.
He told The Washington Post that Mrs May and Mr Macron “would have had no choice but to defend the nuclear deal in the council.”
“I don’t think anyone liked the idea of the president having to sit through stern defences of the Iran deal from May and Macron. He could have got very tetchy, as he did at Nato and the G-7, or walked out of the council causing a diplomatic fuss.”
The most dramatic change in tone from last year’s address will certainly come when Mr Trump moves to discuss North Korea.
Gone will be the insults and threats; in their place, expect to see warm words of encouragement for a man he now considers almost a friend.
“Chairman Kim has been really very open and terrific, frankly,” said Mr Trump on Monday, adding that he hopes to meet him again soon.
Buoyed by the thrill of his historic June summit in Singapore – the first time the leaders of the US and North Korea had ever met – Mr Trump is keen to emphasise that he is making progress on the Korean peninsula, despite critics pointing out that little of note has actually been achieved.
His speech will doubtless recap the “triumph” of the meeting, and stress its unprecedented nature.
His assurance that "everybody can now feel much safer than the day I took office", because "there is no longer a Nuclear Threat from North Korea", saw eye rolls from experts, who pointed out that no actual steps had been taken to remove the threat.
But that doesn’t mean Mr Trump won’t repeat the assertion on Tuesday.
Syria and Yemen
The US president will have little choice but to mention two of arguably the biggest crises in the world today – Syria and Yemen.
Yet don’t expect any dramatic announcement, or change of policy.
The two conflicts are too intractable to shout about. And, given the involvement of Russia and Saudi Arabia respectively, too much of a hornets’ nest to kick.
Mike Pence, the vice president, is hosting an event focusing on Venezuela during the week – and Mr Trump is likely to use his podium to berate the socialist regime in Caracas.
Last year, Mr Trump was brutal, describing the government of Nicolas Maduro as a “corrupt regime” which has “destroyed a prosperous nation by imposing a failed ideology that has produced poverty and misery everywhere it has been tried.”
He added: “To make matters worse, Maduro has defied his own people, stealing power from their elected representatives to preserve his disastrous rule.
“The Venezuelan people are starving and their country is collapsing. Their democratic institutions are being destroyed. This situation is completely unacceptable and we cannot stand by and watch.”
He is unlikely to have changed his tone. Cuba may well also come in for a kicking – despite this being the first general assembly since the Cuban Revolution without a Castro at the helm. Miguel Diaz-Canel, elected in April, is making his own UN debut.
Praising his own team
And finally, expect Mr Trump to lavish praise on his own team.
Mr Pompeo is visibly happier as secretary of state than his poor predecessor, Rex Tillerson. On Monday Mr Pompeo was beaming and jovial as he previewed the days ahead, telling the assembled crowd in a New York hotel that he was relishing what he termed “the Super Bowl of diplomacy”.
“Americans can be proud of how our entire team is executing on the field today,” said Mr Pompeo.
“Americans expect the United States to assert bold leadership on the world stage that reflects our values. And under President Trump, we are certainly leading from the front.”
He is helped by the fact that he has been able to bring with him a slew of envoys, aides and diplomats – Mr Tillerson, by contrast, was proud to bring a skeleton staff, to save money.
Mr Pompeo has in recent weeks appointed a special envoy for Iran policy and another for North Korea nuclear talks, and also hired two to focus on Syria, and one for reconciliation in Afghanistan.
“What we will try to do is have all hands on deck,” said Mrs Haley.
The US delegation this year includes Mr Pence, Steve Mnuchin, the treasury secretary, and Mr Trump’s daughter Ivanka and her husband, Jared Kushner.
On Monday, Mr Pompeo was positively glowing at the thought of the week ahead.
The gathering, he concluded, would enable Mr Trump to deliver “a recap about how his call for every nation to do its part has paid dividends for the United States, and the world, over this past year.”
