His remarks were directed at UK Prime Minister Keir Starmer after the British leader signalled that the UK would avoid becoming involved in a broader war, instead focusing on coordinated efforts with allies.
Dispute over Strait of Hormuz response
At the centre of the disagreement is how to respond to tensions in the Strait of Hormuz, a key route for global oil shipments that has been disrupted during the conflict.
Trump has urged allies, including the UK, to take a more active military role in securing the waterway, calling for naval deployments to protect shipping. He said Britain, once viewed as a leading ally, should be “involved enthusiastically” in reopening the strait.
In contrast, Starmer said the UK was working with partners on a “viable, collective plan” and stressed that any action would need to be coordinated internationally. He added that the situation was complex and not easily resolved.
Military posture and cautious approach
The UK has already deployed some military assets to the region, including minehunting systems and the warship HMS Dragon, which recently left Portsmouth to support defensive operations.
However, British officials have stopped short of committing additional naval forces specifically to secure the strait, emphasising the need for broader agreement among allies.
Starmer also previously declined to allow US forces to use UK bases for initial offensive operations against Iran, though permission was later granted for defensive purposes.
Wider international response
Trump suggested he was disappointed by the UK’s stance, comparing it unfavourably to past cooperation, including joint efforts in Ukraine. He also indicated frustration with what he saw as hesitation from other countries.
The issue has sparked debate across Europe. Germany has ruled out military involvement, with Defence Minister Boris Pistorius stating there would be no participation in combat operations, though diplomatic efforts would continue.
Within NATO and the European Union, there has been limited appetite for expanding military missions related to the conflict, with officials stressing the defensive nature of existing alliances.
Domestic and political reactions
In the UK, political figures have expressed mixed views. Some have raised concerns about the risks of becoming drawn deeper into the conflict, warning against “mission creep”.
Others have questioned whether the government is acting decisively enough, particularly in its coordination with allies.
Starmer has maintained that the UK remains a strong partner to the United States but emphasised that decisions would be guided by national interests.
Meanwhile, the government has announced financial support for households affected by rising energy costs, as disruptions to oil supplies continue to push prices higher.
