UK Prime Minister Keir Starmer is heading into high-stakes discussions with US President Donald Trump at the White House, seeking both security assurances for Ukraine and economic relief for Britain.
His visit follows a wave of diplomatic efforts by European leaders to persuade the US to maintain its commitment to Ukraine while navigating complex trade tensions.
Boost from the US on Defence Spending
Washington has given a nod of approval to the UK’s pledge to increase defense spending to 2.5% of GDP.
A senior Trump administration official expressed satisfaction with Starmer’s decision, though the US continues to push NATO allies toward a more ambitious 5% target.
In addition, the UK’s offer to contribute troops to any future Ukraine peacekeeping efforts has been recognized as a significant commitment.
The Challenge of Convincing Trump
Despite Starmer’s diplomatic push, President Trump remains firm on key policies.
He has signaled reluctance to extend security guarantees to Ukraine, emphasizing that Europe should take more responsibility.
He also reiterated his stance that Ukraine’s bid to join NATO played a role in escalating the conflict with Russia.
Furthermore, Trump is pressing ahead with his plan to impose 25% tariffs on the European Union, citing what he perceives as unfair trade practices—a move that could impact British exports, particularly in the steel industry.
Starmer’s Case for a Security ‘Backstop’
Speaking en route to Washington, Starmer stressed the importance of a strong security framework to prevent future Russian aggression.
He argued that without a firm US commitment, any ceasefire agreement could merely serve as a pause before Putin regroups and resumes hostilities.
The Prime Minister underscored that long-term peace in Ukraine requires robust security guarantees rather than a fragile truce.
A Delicate Balancing Act
While advocating for Ukraine’s security, Starmer must also navigate Trump’s unpredictable stance on European affairs.
The UK government is keen to ensure that Ukrainian President Volodymyr Zelensky is involved in any peace discussions, despite Trump’s past criticisms of him.
Meanwhile, Downing Street aims to avoid open conflict with the US president, whose return to power has significantly reshaped global diplomacy.
European Leaders Rally for Support
Starmer’s meeting is part of a broader European effort to engage Trump on Ukraine.
French President Emmanuel Macron kicked off the diplomatic push earlier in the week, and Ukrainian President Zelensky is set to visit Washington next, aiming to secure US backing in exchange for access to Ukraine’s rare mineral resources.
These discussions will culminate in an emergency summit on European security in London.
Navigating Diplomatic Landmines
Beyond Ukraine, the UK is also managing sensitive negotiations with the US on other geopolitical issues.
Foreign Secretary David Lammy acknowledged that no agreement on the future of the Chagos Islands—home to the strategic US military base on Diego Garcia—can move forward without Trump’s consent.
This adds yet another layer of complexity to Starmer’s visit.
What Lies Ahead?
With trade disputes, NATO tensions, and security commitments all on the table, Starmer’s White House visit is a diplomatic balancing act.
His challenge is to secure key agreements without provoking a president known for his tough negotiating style.
The coming days will reveal whether his approach can yield meaningful results or if the UK must brace for a more challenging transatlantic relationship.
