Operation Epic Fury unleashed overwhelming firepower on Iran and a Trump broadside against Britain’s prime minister. The president belittled Keir Starmer as being no comparison to Winston Churchill, raged against caveated British support and placed Britain’s standing as America’s “greatest ally” firmly in the past tense.Starmer refused the bait. His government is privately contemptuous of the Trump administration. But he still needs to deal with the US president and how he should do that following the recent vitriol is a very live question.Winston Churchill appropriated the term special relationship after the second world war to refer to the myriad Anglo-American connections. Some were government-to-government, spanning privileged diplomatic, economic, military, nuclear and intelligence cooperation. Others were historical and cultural, from which evolved a sentimental myth of special relations based on uniquely entwined histories, a common language, similar values and so forth. For 80 years, Britain and the US stood shoulder-to-shoulder in defence of a liberal international order they fashioned from the ruins of war. The US became a hyperpower. Post-imperial Britain settled as a leading medium-sized power. But the song remained the same – at least until the Trump administration’s discordant note.Brexit made Britain even more dependent on US power. Starmer, therefore, followed almost every prime minister since the second world war in seeking close personal relations with US presidents and the preservation of Britain’s standing as America’s foremost ally.In fairness, of all the national leaders aspiring to be a “Trump whisperer”, Starmer has been one of the more successful. Routine extensive government-to-government dialogue has been combined with carefully choreographed leveraging of cultural connections to massage the president’s ego. Particularly noteworthy has been recruitment of British royalty to the cause, including the president’s historic second state visit in September 2025.Still, Trump’s personality and his administration’s policies remain challenging. Starmer risks association with Trump’s political toxicity if he gets too close and will be questioned about whether any rewards from such courtship outweigh the costs. Fidelity above all elseThe Trump administration is anomalous. Unlike previous administrations, it does not consistently work with the British government to put a positive face on Anglo-American relations. The feel-good sentiment generated by the second state visit, for example, dissipated rapidly once Trump carelessly attacked British policies shortly afterwards in the United Nations. Meanwhile, Trump’s prioritises fidelity above competence and centralises power in his White House. These tendencies, and his suspicion of expertise within the “deep state” weaken Britain’s ability to feed into the American foreign policymaking process. Trump’s inconsistency, preference for diplomacy by social media, and frequently provocative and erroneous statements often trap Starmer between trying to smooth consequent tensions (in which case he appears as a Trump apologist) or rebutting the president. This was clear when Trump threatened Canadian sovereignty, when he repeatedly implied he would invade Greenland and when he attacked the commitment of British troops in Afghanistan.Finally, and most importantly, the Trump administration is undermining the liberal international order, casting its anti-liberal, anti-modernist and anti-globalist tendencies against Britain’s preferences for international law, multilateral institutions, collective security and international free trade.What should Starmer do now?On balance, Starmer’s best option for now is to hope, hedge and wait. In the short term, Downing Street will hope that US mid-terms return a Congress less pliant to Trump’s ambitions and that legal actions through American courts continue their disruption. In the longer term, the next three years will constitute a damage-limitation exercise while the world waits for Trump’s successor to arrive. The hope will be that whoever the next president is, Anglo-American relations will improve simply from being liberated from the personal and organisational chaos wrought by Trump.During this interim, Starmer will routinely align Britain with the US provided doing so neither overly compromises British interests nor further weakens the liberal international order. He will also probably swallow bile and continue to woo Trump. That will potentially include leveraging the 250th anniversary celebrations of American independence. Even this, however, will need balancing against the risk of inferred endorsement of Trump ahead of the midterms. Meanwhile, the British government will de-emphasise the significance of personalities to the robustness of Anglo-American relations and hedge against over-reliance on the US. This means building ever closer relations with Europe, continuing cautious engagement with China and outreach to other centres of economic power. Starmer should also seek stronger relations with Canada’s Mark Carney, who has emerged as the most capable leader of the world’s medium-ranking powers and who most shares Britain’s conundrum of needing close but not over-dependent relations with Washington.One final cautionary note. Trump dominates headlines, but he is merely an awkward symptom of the biggest challenge to the special relationship since its inception. The international order is in flux. How it is reshaped will determine whether Britain and the US remain shoulder to shoulder or return to being the distant cousins of the interwar period.The latter is a scenario that ought to cause British officials sleeplessness. A US retreat to a neo-isolationism that broadly embraces the Maga logic would pass the mantle of principal guardianship of the liberal international order to the European Union. Britannia would then face a not-so-splendid isolation, self-exiled from the union and powerless to prevent retreat of the Atlantic shoreland.Stephen Marsh does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment.
