When Donald Trump stood before the United Nations General Assembly to celebrate American military power and warn Iran of “annihilation,” the silence from the international community revealed deep structural fractures in the post-1945 global order. According to Jostein Hauge, a scholar of international political economy, the address signaled that the rules-based international order is dead.
UN General Assembly Reception and the Silence of Member States
The speech delivered at the United Nations triggered immediate walkouts from the Iranian and Cuban delegations. Other governments had criticized Washington elsewhere, meaning the address did not go completely unanswered. Yet, as Ashok Swain, professor of Peace and Conflict at Uppsala University, observed, the General Assembly floor lacked any collective protest, institutional interruption, or immediate challenge to the podium’s language.
Swain argued that this muted response was troubling because the United Nations is supposed to be the principal forum to challenge threats to peace, attacks on human dignity, and the rejection of collective global responsibilities. Instead of a strong institutional pushback, the assembly listened as Trump defended the US war against Iran, criticized the International Criminal Court, rejected international approaches on climate change and artificial intelligence, and attacked an international system that he claimed constrains American sovereignty.
Did you know? The post-1945 international architecture was built around a simple idea that countries should have a place to settle their disputes without turning to conflict.
International Law, State Sovereignty, and the Threat to Tehran
Trump’s ultimatum giving Tehran a choice between a deal or “annihilation” directly clashed with the legal framework governing the use of force between states. International law places significant restrictions on such actions, with limited exceptions including self-defense or authorization by the Security Council. While legal scholars have argued that US and Israeli attacks on Iran violate the UN Charter, Washington and Israel have presented their own legal justifications.
Before Trump took the podium, outgoing UN Secretary-General Antonio Guterres and the president of the General Assembly warned that geopolitical fault lines were widening. They cautioned that international law and humanitarian law cannot be applied selectively and urged that international law and cooperation prevail over force. Trump’s address countered those warnings directly by presenting military power as the mechanism for securing US interests.
Power Asymmetries and the Critique from the Global South
The gap between what the UN says and what it can enforce exposes long-standing structural inequalities. As Swain noted, when governments remain restrained against powerful states while speaking much more forcefully against weaker ones, silence reinforces a hierarchy of power. The United States is a permanent member of the Security Council and has a veto, maintains an enormous military, and has a network of alliances.
This dynamic fuels criticism from the Global South regarding selective enforcement. While a small or economically vulnerable country in the Global South that threatened another state can face sanctions, diplomatic isolation, and potentially international intervention, the US possesses the economic and military capacity to resist those pressures. Swain warned that this asymmetry weakens the legitimacy of the rules themselves, creating a dangerous set of incentives where smaller states may seek nuclear deterrence or stronger military alliances rather than relying on international law.
Future Trends Toward a More Transactional Global Order
The normalization of the idea that military threats and force are legitimate tools of ordinary foreign policy carries consequences far beyond the immediate conflict with Iran. Other global powers—including Russia, China, and India—are asking why they should accept restraints that Washington itself treats selectively. Swain cautioned that this erosion could lead to a more openly transactional international system where arms control becomes harder, disarmament becomes harder, and smaller states become more vulnerable to the calculations of larger ones.
Although institutions like the UN remain indispensable for humanitarian action and basic diplomacy, their political credibility faces erosion. As Hauge and Swain suggest, an international order does not need to vanish overnight to lose its authority; it decays when powerful states stop believing there will be consequences if they break the rules.
Frequently Asked Questions
What did Donald Trump say during his UN General Assembly address?
Trump defended the US war against Iran, criticized international institutions like the International Criminal Court, rejected international approaches to climate change and artificial intelligence, and warned Tehran that it faced “annihilation” without a deal.
How did international scholars react to the speech?
Scholars such as Jostein Hauge and Ashok Swain expressed deep concern over the muted institutional response from the UN General Assembly. Hauge declared that the rules-based international order is dead, while Swain warned that the speech helps establish the precedent that international law constrains the weak more effectively than the powerful.
Does international law permit military strikes against sovereign states?
International law places significant restrictions on the use of force between states, with limited exceptions including self-defense or actions authorized by the Security Council. While legal scholars have argued that recent attacks on Iran violate the UN Charter, the US and Israel have presented their own legal justifications.
