There is cautious optimism that a 'majority of multilateralists' may be able to enduringly reshape the world order, according to diplomats and analysts. Brazil's ambassador to London, Antonio de Aguiar Patriota, noted a new division in the global north between a unilateralist superpower and a majority of multilateralists, citing the 'highly unpopular and illegal war in Iran' as a vivid example of chaos bred by unilateralism.
The argument that the current dark era of American unilateralism may be coming to an end is gaining momentum as other Western countries recover their poise and place long-term bets beyond the US security blanket. They have seen meagre protection for Gulf monarchies and little promotion of European interests in Ukraine, leading many to realise they are better off with diverse friendship groups.
Spanish Prime Minister Pedro Sánchez, speaking in China, described a multiplication of poles of power and prosperity, not a transfer of hegemonies. This sentiment is echoed across Europe, including by German Chancellor Friedrich Merz, who likened Donald Trump's misjudgment in Iran to predecessors' invasions of Iraq and Afghanistan.
Many European countries are embracing Trump's advice to take more responsibility for defence, constructing a bypass around America. On the global stage, demands grow for Western powers to relinquish outsized representation in global institutions in favour of the global south. These changes, while not linear, are accelerated by mutual resentments between Trump and Europe over Iran.
Harvard Professor Stephen Walt explained that American influence depends partly on how it is viewed. The Trump administration has sent a message that it does not know what it is doing, making other states less likely to rely on US advice. He added that the Iran war showed the administration cared only about Israel, at the expense of other allies in Europe and Asia.
