The United Kingdom is one of the United States’ closest allies, sharing history, culture, and strategic interests. However, this relationship has been strained by the recent conflict in the Middle East, with US President Donald Trump repeatedly slamming British Prime Minister Keir Starmer for his near non-existent role in the Iran War.
Tensions escalated when Trump told Sky News on April 15 that he would review the tariff relationship between the two countries, with Starmer retorting, “I’m not going to change my mind, I’m not going to yield, it is not in our national interest to join this war and we will not do so.”
To ease tensions, King Charles III was in the United States two weeks later for an official visit to fulfill an agenda that would have been the Prime Minister’s. Given Trump’s fascination with the British royal family, this exchange may have been a soft-power gesture to ensure the White House does not dismiss London as an ally.
The role of King Charles III was, in fact, a diplomatic buffer in the very tense issue between Trump and Starmer. Charles III's maneuvering aimed to improve relations between the US and the UK.
While the Republican president adopts a more personalistic style, the British Prime Minister maintains an institutional tone closer to European diplomatic traditions. In this context, Starmer’s positions — pro-Europe and in favor of strengthening NATO — tend to create friction with Washington, which, under Trump, has adopted a more confrontational stance toward historical allies, as evidenced by incidents involving Greenland.
This tension is best understood within a broader historical context, such as the Suez Crisis, when the UK faced significant international pressure despite its ideological alignment with the US during the Cold War. British, French, and Israeli forces invaded Egypt in 1956 in response to the nationalization of the Suez Canal, but were forced to withdraw under intense pressure from the US and the Soviet Union.
For decades, convergence was the rule: Margaret Thatcher had a close relationship with Ronald Reagan, as did Tony Blair with George W. Bush. Now, Starmer could be marking a turning point, as he is the first British leader in decades who is less automatically aligned with the US.
Despite the political misalignment, the bilateral relationship remains underpinned by structural pillars. Among these, the military alliance within NATO, intelligence cooperation through the Five Eyes agreement, and the economic interdependence between the City of London and Wall Street stand out.
Nevertheless, the contrast is growing: while Starmer’s UK seeks rapprochement with Europe, the US under Trump signals a distancing from traditional allies. This scenario raises questions about the partnership’s future direction, including whether the UK will explore new strategic approaches in an international system increasingly polarized between major powers.
Nonetheless, Charles III’s visit to the US also had a domestic dimension—an effort to reinforce the image of the British monarchy, and, in particular, of Charles III, in the eyes of the public. The sovereign does not yet possess the same symbolic capital as Queen Elizabeth II, which creates a need to strengthen his credibility and legitimacy as head of state.
The British monarchy is usually discreet in international relations, but the breakdown in relations called for a more proactive approach.
Responding to Trump’s recurring claim that without the US, Europe would “speak German,” Charles replied, “If it wasn’t for us, you’d be speaking French.” The statement combined good humor with diplomatic calculation and served a dual purpose. On the one hand, it countered the tone of Trump’s statement, which was considered impolite, and on the other, it recalled, in a historical and symbolic way, that the construction of the liberal order has always been the result of their shared efforts.
Another sensitive point of contention involves the Falkland Islands. Recently, Trump stated that the US would support Argentina’s attempt to recover the territory—a position that directly contradicts the UK’s sovereignty and further strains the relationship with London.
However, this signal should be interpreted cautiously and in the broader context of Trump’s foreign policy. It is not a structural shift in the US’s alignment but a circumstantial rapprochement with Javier Milei’s government. It is not an alliance with Argentina but with Milei.
This distinction is central and already evident in the personalistic nature of Trump’s foreign policy. Rather than relying on established institutional guidelines, his positions tend to vary according to political and ideological affinities with specific leaders. This means that, in the event of a change of government in Buenos Aires, any US support for Argentina’s claim to the Falklands could quickly lose momentum or even disappear.
Furthermore, this type of statement has a more rhetorical than practical component. The Falklands issue is historically sensitive and involves not only territorial sovereignty but also the UK’s military and diplomatic commitments—making any effective US support for Argentina highly complex and costly on the international stage.
In this sense, Trump’s speech functions more as a political gesture, consistent with his direct and provocative style, than as a concrete indication of geopolitical reconfiguration.
Thus, the growing unpredictability of international relations — marked by personalistic leadership and a more fragmented global order — means that historically stable issues, such as Washington’s position in territorial disputes involving traditional allies, are now treated as more volatile, heightening uncertainty for both partners and adversaries.
