Keir Starmer's tenure as Prime Minister was forged in the fire of a tumultuous international landscape, with Donald Trump's return to the White House posing a significant challenge to Britain's security and global standing. As he navigated the aftermath of Brexit and ongoing conflicts, Starmer's foreign policy approach was put to the test, sparking debate over its long-term implications for the nation.
A critical early phase saw an unlikely rapport develop between Starmer and Trump, exemplified by a February 2025 meeting at the Oval Office where the Prime Minister personally extended an invitation from King Charles for a second state visit. This unprecedented gesture was publicly accepted by Trump, paving the way for a carefully managed state visit in September that temporarily aligned the UK and US on condemning Russia's actions in Ukraine, despite previous leanings.
The British government demonstrated significant diplomatic influence during this period, particularly concerning Ukraine. Following a meeting between Trump and Russian President Vladimir Putin where the US President appeared to favour Ukraine ceding territory, Prime Minister Starmer played a key role in demonstrating robust support for Kyiv. A request from Ukraine led to President Zelenskyy being flown by helicopter to meet King Charles at Sandringham, a clear signal of British solidarity that helped counter the narrative of territorial concessions.
However, this period of relative harmony was short-lived, as goodwill between the UK and US evaporated following a US-Israeli attack on Iran in February. The UK was not consulted or informed prior to these strikes, leading to public disagreement and criticism from President Trump over Starmer's initial refusal to allow the use of RAF bases for bombing Iran.
Despite escalating tensions and a month of public jibes from President Trump, Prime Minister Starmer maintained a measured response. He firmly articulated that his decisions were based on Britain's national interest, opting to avoid a deeper split with the US while also refusing to fully join the conflict initiated by Trump. The UK's involvement was limited to allowing attacks on Iranian missile launch sites from RAF Fairford in Gloucestershire. Sir Peter Westmacott, a former UK ambassador to the US, has noted that foreign policy has been an 'area of relative strength' for Starmer, despite the challenges posed by the US President's actions.
