A speech to divide the world
The United Nations General Assembly convenes each year in New York as a theatre for global diplomacy. It is a place for caution. Leaders from every recognised state are meant to address shared crises, from climate change to conflict, using language that is deliberately measured and often oblique. Speeches are drafted and redrafted by civil servants to avoid misinterpretation, to build consensus, and to slowly nudge complex negotiations forward along established channels. This is the forum’s purpose. It is built on process. The institution itself is designed to lower the temperature of international relations, not to raise it. It seeks to manage divisions.
Donald Trump’s address on Tuesday did not follow the script. The former American president ignored the usual diplomatic conventions entirely. He spoke directly. He presented the world with a stark choice regarding Iran. Annihilation or a deal. The president said he had a ‘big decision to make’. This was not the language of negotiation. It was the language of an ultimatum, delivered from the most prominent stage in international affairs to an audience of supposed partners and peers. The words were simple. Their meaning was not.
The moment was made sharper by its timing. It came just hours after UN Secretary General António Guterres had used the same lectern to deliver a sober warning. He had spoken of a world where geopolitical divides were growing into dangerous chasms. Guterres cautioned the assembled heads of state and government that global cooperation was fracturing precisely when it was most needed, creating an environment of profound instability. His remarks painted a picture of a system under immense strain. He urged unity. He called for dialogue.
Then Trump spoke. His speech was not a response to Guterres’s appeal. It was a perfect and immediate illustration of the very problem the Secretary General had just described. Instead of building bridges, Trump drew a line. Instead of seeking common ground on a difficult security issue, he presented a binary future of total capitulation or total destruction for the Iranian state. The entire diplomatic apparatus of the United Nations, designed for patient compromise and multilateral action, was bypassed in a single sentence. The choice was clear. The consequences were not.
The art of the impossible deal
To understand the speech, one must first translate its terms. What is a deal? It is not a compromise. It is not a meeting of equals who find a middle ground through patient negotiation and mutual respect. For Donald Trump, a deal is an act of submission by the other party. He wants total victory. The opponent must surrender completely, accepting terms that were previously unacceptable and allowing him to claim a singular, historic triumph. This worldview was not shaped in the foreign policy establishments of Washington. It was forged in the world of high stakes property development, where leverage is everything and a successful negotiation is one that crushes the opposition into acquiescence. The offer of a deal, in this context, is simply the final demand presented before the wrecking ball is deployed. There is no plan B.
This approach has a history. A recent one. The world has already witnessed what happens when Trump decides an existing international agreement is not good enough for him. He walked away from the 2015 Iran nuclear deal. That agreement, formally the Joint Comprehensive Plan of Action, was the product of years of painstaking diplomacy between Iran, the United States, Britain, France, Germany, Russia and China. It successfully curbed Iran’s nuclear programme. International inspectors verified it was working. Trump called it ‘the worst deal ever’ and unilaterally withdrew the United States, reimposing crippling sanctions on the Iranian economy in the declared pursuit of a ‘better deal’. That better deal never materialised. Iran, predictably, restarted the sensitive nuclear work it had previously frozen. The old deal was broken. The new one never came.
The offer made at the United Nations is a calculated political manoeuvre. It is a trap. It is designed to corner the Iranian leadership into an impossible position while providing the White House with political cover. By dangling the possibility of an agreement, Trump can present himself to his domestic base and to wavering international partners as a man willing to pursue peace. A reasonable man. He can claim that he offered an off ramp. He can say he gave diplomacy a chance. This narrative is crucial. It shifts the burden of responsibility. It reframes the entire crisis. The choice is no longer about an American president deciding on war. It becomes about an Iranian regime supposedly rejecting a generous offer of peace.
This forces Tehran’s hand. The calculation is brutal. If Iranian leaders agree to negotiate on these terms, they legitimise Trump’s entire strategy of coercion and abandon the principle that they do not respond to threats. They would enter talks from a position of profound weakness, with the expectation that they would have to concede on their missile programme and regional foreign policy, issues they have always considered non negotiable. But if they refuse to talk, as is far more likely, they walk directly into the trap. Trump and his allies can then declare that diplomacy has failed. They can insist that they tried. The responsibility for what comes next, for the threatened ‘annihilation’, is thus placed squarely on Tehran. It is a choice with only one real outcome.
Every capital was listening
Donald Trump was not speaking to Iran alone. The world listened. He stood at the famous green marble rostrum of the United Nations General Assembly, but his primary audience was far from New York City. His words were a direct appeal to the voters who form his political base back in the United States, people who respond to a show of strength. For them, the stark choice between a triumphant deal and total destruction is a familiar and effective piece of political theatre. It is strong. It is simple. It is the brand. This rhetoric presents a president who is tough on foreign adversaries, a leader unafraid to issue ultimatums while still claiming the mantle of a potential peacemaker. This binary logic bypasses the complicated realities of Middle East diplomacy, offering instead a clear, populist message perfectly suited for an election campaign.
In Jerusalem, the message was welcome. In Riyadh, it was a relief. For Israel and Saudi Arabia, Iran's two great regional antagonists, the words from the UN podium were a powerful guarantee from their principal security partner. These governments, which vehemently opposed the 2015 nuclear accord, had celebrated Trump's withdrawal from that deal. This speech was the logical next step. They have watched with mounting alarm as Tehran has expanded its influence through proxy forces in Lebanon, Syria, Iraq and Yemen. They fear an American retreat. They fear compromise. Trump's explicit threat of annihilation, however blunt for a diplomatic forum, offered them profound reassurance. It confirmed that the policy of 'maximum pressure' would continue and that the United States had not abandoned them to face a common enemy alone.
The calculations in Moscow and Beijing were entirely different. Russia and China are not spectators. They are deeply invested actors in this drama. For them, Trump's speech presented both a danger and a distinct opening. An American war with Iran would catastrophically destabilise a region where both powers have significant economic and security interests. This includes China's vast energy needs and its Belt and Road Initiative infrastructure projects, and Russia's critical military bases in Syria. The instability would be bad for business. Yet the opportunity is also clear. Every threat from Washington pushes Tehran further into their embrace, strengthening alliances and creating dependencies that Moscow and Beijing can exploit for their own strategic gain. The rhetoric also allows them to use their veto power at the UN Security Council to portray themselves as the reasonable great powers, the defenders of international law and stability, in contrast to an erratic America.
Tehran's calculation has not changed
In Tehran, there was no panic. The Islamic Republic has existed under the shadow of American hostility for nearly half a century. It is a foundational principle. The regime survived the aftermath of its own 1979 revolution, a brutal eight year war with an Iraqi state then backed by Washington, and generations of economic sanctions designed to bring it to its knees. American presidents have come and gone. Each has issued threats. For the clerics and commanders who hold power in Iran, Donald Trump's ultimatum at the United Nations was not some shocking new development but another chapter in a very old story. The rhetoric of the 'Great Satan' is met with the threat of annihilation. The script is familiar.
The real impact of the speech is internal. It is a political gift for Iran’s hardliners. These factions, centred around the Islamic Revolutionary Guard Corps and the office of the Supreme Leader, have consistently argued that the United States is fundamentally untrustworthy and that its ultimate goal is not negotiation but the destruction of their state. Trump’s withdrawal from the 2015 nuclear deal had already validated their cynicism, and his threat to 'annihilate' their country provides them with the ultimate vindication. They can now turn to any remaining advocates of diplomacy and present this speech as absolute proof of American perfidy. Their argument is simple. Engagement is weakness.
From this perspective, there is no 'deal' to be made. The choice presented by the American president, between a new agreement and total destruction, is viewed as a transparent trap designed to force Iran into a humiliating surrender or provide a pretext for war. The regime's survival is paramount. Its network of regional proxies and its ballistic missile programme are not seen inside Iran as tools of aggression, but as essential pillars of a defensive strategy meant to deter an attack from a vastly superior conventional military power. Mr Trump's words do not persuade Tehran to abandon these tools. They reinforce the conviction that such defences are more necessary than ever. The calculation has not changed. It has simply hardened. Diplomacy is now further away.
Europe is caught in the middle
For Europe, the speech is a disaster. It is a familiar disaster. The continent’s leaders are once again caught between their main security ally and their own strategic interests. In capitals from London to Berlin, Donald Trump’s ultimatum of annihilation or a deal was received with quiet horror, representing a direct assault on a foreign policy framework built patiently over decades. That framework prioritises international law and negotiated settlements. Mr Trump's speech tears it apart. The choice it presents to Europe is impossible, forcing it to either follow the United States into a potential war or break with Washington and risk the transatlantic security alliance that has underpinned European defence for eighty years.
This is a wound reopened. The principal European powers were the proud architects of the 2015 nuclear accord. London, Paris and Berlin saw that deal, the Joint Comprehensive Plan of Action, as the ultimate proof that complex proliferation crises could be solved without conflict. It was their model for the twenty first century. Mr Trump’s withdrawal from that agreement in 2018 was a deep humiliation. His address to the UN General Assembly on 22 September felt like the final, public demolition of their signature diplomatic achievement. They now face two nightmares. The first is a devastating war. The second is a nuclear armed Iran. The American president's rhetoric makes both seem closer.
Europe’s weakness has been exposed before. After the American withdrawal from the nuclear deal, European governments scrambled to keep it alive. They announced a special purpose vehicle, a financial channel called INSTEX, which was designed to allow humanitarian trade with Iran while bypassing American sanctions. It was a complete failure. The mechanism proved unable to provide any meaningful cover for European companies that were terrified of being locked out of the far more lucrative American market. Their powerlessness was absolute. This is the core of their predicament. Their primary military ally under the NATO treaty is the same country actively sabotaging the diplomatic path they believe is essential for their own security.
So what can they do? The speech forces a flurry of activity. European diplomats will now work furiously behind the scenes to find some kind of off ramp from this crisis. They will try to create space for de-escalation, hoping to craft a third way that is neither the humiliating deal Mr Trump demands nor the war he threatens. This means talking. They will talk to officials in Washington. They will use their strained diplomatic channels to communicate with Tehran. They will coordinate with Russia and China, both of which share Europe’s interest in preventing a hot war in the Persian Gulf. Their influence is limited. The speech showed that. The American president was not speaking to them. Europe was relegated to the role of anxious spectator. It is a deeply uncomfortable place to be.
What to watch for in the Gulf
The speech changes everything. Every actor must now recalculate. The immediate focus is the Gulf. Analysts will watch for any new American deployments, particularly the movement of an aircraft carrier strike group towards the Strait of Hormuz or an increase in strategic bomber patrols over the region. They will also scrutinise the actions of Iran’s Islamic Revolutionary Guard Corps Navy, a force with a history of using its small, fast attack craft to harass international shipping. A single mistake could be fatal.
Diplomacy matters just as much. Statements will be analysed. Russia and China have a strong interest in preventing an American war with Iran, being both signatories to the original 2015 nuclear deal and permanent members of the UN Security Council. Their official response to Mr Trump’s ultimatum will show whether they plan to offer Tehran more robust diplomatic or even material support. Beijing is now a vital lifeline. It provides crucial economic relief to an Iran crippled by American sanctions. Their reaction matters. Their words will be weighed carefully in Tehran.
Then there is the quiet diplomacy. This is often what counts. Secret talks can achieve what public podiums cannot, sending signals far from the glare of the United Nations. Countries like Oman have acted as intermediaries before. Intelligence agencies will watch for any unusual activity in its foreign ministry, for any quiet flights between Muscat and the Iranian capital. The speech on 22 September was public theatre. The real work of preventing a war, or failing to, will happen in private. It will happen through shadow conversations and military realignments. Every government, from Riyadh to Moscow, must now reassess its position. The president has forced their hand.
