🇬🇧 Voters Say UK Needs a New European Defence Pact Amid Concerns Over Trump

Polling Shows Majority Support for a New Pact

A JL Partners poll of 1,562 British adults conducted in mid-December found that:

55% of voters believe the UK should form a new defence alliance with European countries that operates independently of the United States.
Just 11% oppose such an initiative.
The framing of the question centred on concerns that the US — under President Donald Trump — might not uphold its NATO commitments in the event of a Russian attack on the UK or Europe. (Yahoo News)

This represents a significant shift in public confidence in the traditional “special relationship” with Washington — a bond that has underpinned UK defence policy since World War II. (Yahoo News)

Context: Why Voters Are Worried

Uncertainty Around Trump’s NATO Commitments

President Trump has repeatedly:

Criticised some European allies as “weak” and urged them to spend more on their own defence,
Suggested in past rhetoric that the US might not automatically come to the defence of NATO members that fail to meet spending targets. (Yahoo News)

These types of comments have reinforced public anxiety that NATO’s cornerstone — Article 5, under which an attack on one ally is treated as an attack on all — might not be guaranteed in future conflicts. (Yahoo News)

Russian Threat Still Central in Public Mind

With ongoing geopolitical tensions involving Russia — especially over Ukraine — voters are sensitive to the idea of a European defence structure capable of responding even without direct US involvement. Leaders such as NATO Secretary General Mark Rutte have warned that Russia’s missile capabilities and ongoing aggression make collective defence more urgent than ever. (The National)

Case Study: Hypothetical “UK-Europe Defence Pact”

What Voters Think a Pact Should Do

According to the poll and related commentary:

A new pact would focus on collective security without relying on the United States.
It would theoretically strengthen Europe’s ability to deter or respond to a conflict directly involving Russia.
Many voters view this as necessary because they no longer trust the US to intervene militarily, even for historic allies like the UK. (Yahoo News Defence Policy Moves Already Underway

While no full “European Defence Pact” currently exists outside NATO, there have been ongoing efforts to deepen UK-EU and European defence cooperation:

The UK and EU have agreed on a Security and Defence Partnership that includes areas like cyber, maritime and hybrid defence. However, full integration into the EU’s military funds and programmes remains unfinished and politically complex. (Chatham House)
NATO members, including the UK, are considering increased defence spending targets under pressure from Trump-influenced calls for allies to boost military investment. (Sky News)

These developments illustrate that the idea of a more autonomous European defence is not just theoretical — though it remains politically and logistically complex. (Chatham House)

Voices From Across the Political Spectrum

Pro-Pact Views

Many voters explicitly feel Europe should take its own defence into its own hands rather than rely on unpredictable US commitments.
Security experts argue that greater European autonomy would reduce dependence on external actors and enhance regional stability — though such a pact would still likely work alongside NATO rather than fully replace it. (Yahoo News)

Skeptical or Cautious Views

Critics (not necessarily reflected in the poll) worry that decoupling from the US could weaken NATO and divide Western strategic unity.
Defence analysts note that Europe still relies on the US for key capabilities such as strategic airlift, intelligence infrastructure, and nuclear deterrence — areas where European members are still building capacity. (The National)

Potential Diplomatic and Strategic Impacts

On NATO

Shifting public sentiment toward a Europe-only defence pact could pressure NATO to evolve — but it also raises questions about the alliance’s future cohesion. Analysts warn that:

Distrust of the US under Trump may be driving Europe closer together,
But NATO remains the principal framework for Euro-Atlantic defence and would need to adapt to any major rebalancing. (The National)

On UK Foreign Policy

If UK voters continue to favour a European defence pact:

Government policy may increasingly mirror European priorities, especially around shared military procurement, readiness exercises, and rapid deployment forces.
Meanwhile, UK-US relations — historically central to British defence strategy — could see intensified public and parliamentary scrutiny. (Yahoo News)

Why This Matters Now

This polling result doesn’t mean a new defence treaty will be signed tomorrow — but it reflects:

A significant shift in public perceptions of security guarantees.
Growing sentiment that Europe should shoulder more of its own defence burden, particularly if US leadership is seen as unpredictable.
A broader debate about the future of transatlantic alliances at a time of rising global tensions with Russia and other powers. (Yahoo News)

In short, Britain’s voters appear ready to rethink longstanding defence assumptions in favour of a more autonomous European security architecture — a debate that will influence UK foreign policy for years to come. (Yahoo News)

Here’s a detailed, case-study and commentary-style report on the emerging sentiment among UK voters that the country needs a new European defence pact, largely driven by concerns over President Donald Trump’s reliability as a security partner — including real polling data, context, reactions, and strategic implications.

🇬🇧 Voters Say UK Needs New European Defence Pact Amid Trump Concerns — Case Studies & Comments

Key Polling Insight

A JL Partners poll conducted in mid-December found that **55% of British voters believe the UK should join a new defence alliance with European countries independent of the United States, with only 11% opposed. This reflects deep public anxiety over whether the US — under President Trump — would automatically defend the UK in a major conflict, particularly with Russia. (Yahoo News)

Poll Details

Sample size: 1,562 adults
Timing: 13–14 December 2025
Core finding: A majority favour a European pact without reliance on Washington.
Many voters fear that NATO’s traditional guarantees, backed largely by the US, may not hold under a Trump administration. (Yahoo News)

Case Study 1: Shifting UK Public Opinion

From “Special Relationship” to Strategic Doubt

Historically, the UK has relied heavily on its “special relationship” with the US as a cornerstone of defence policy. But recent polling data shows a sharp decline in British confidence in the US as a reliable ally, with only around 30% now saying the US is a friendly ally — down from higher levels in previous years. A growing share even thinks ties with Europe should be prioritised over those with the US. (yougov.co.uk)

Commentary:
This change isn’t just abstract — it stems from widespread negative sentiment toward the Trump administration’s approach to global security. Many Britons now believe that Europe should be more self-sufficient and less dependent on Washington, especially given Trump’s past criticisms of NATO and allies’ defence spending. (yougov.co.uk)

Case Study 2: Geopolitical Drivers — Russia & NATO Pressures

Threat Perception & Missile Risks

Concerns about Russia’s intentions loom large in public thinking. NATO’s leadership has warned that Russian missile capabilities and hybrid tactics pose an urgent threat to European security, reinforcing voter scepticism about relying solely on the US. (The National)

Commentary:
Although NATO remains the central framework for collective defence, voters increasingly argue that Europe must be capable of defending itself, even without automatic US involvement. This drives support for a European defence pact that could complement or run alongside NATO. (The National)

Case Study 3: Strategic Options Being Discussed

Concept: UK–Europe Defence Arrangement

The idea behind a new European defence pact would be to ring-fence military commitments among European powers (including the UK) to ensure collective security without being fully dependent on US military backing. Proposals of this nature include:

Mutual defence commitments among European states
Co-ordination of military planning, procurement, and deployment
Enhanced interoperability of European forces

Although such a pact remains theoretical, the poll indicates public appetite for deeper UK–Europe defence cooperation. (Yahoo News)

Comment:
Experts say a standalone pact would take years to develop and would not replace NATO, but could act as a supplementary security mechanism that reassures citizens worried about US unpredictability.

Voices & Reactions

Pro-Pact Sentiment

Supporters argue that:

The US may not be reliable under Trump in the event of a major European conflict.
Europe needs greater strategic autonomy, particularly with Russia’s growing assertiveness.
A pact could be a historic shift towards European security cooperation — one that reflects 21st-century geopolitical realities. (Yahoo News)

Criticism & Caution

Critics caution that:

A European pact could fracture NATO unity, weakening the longstanding transatlantic alliance.
European militaries still depend on the US for capabilities like strategic airlift, intelligence, and nuclear deterrence.
Practical implementation (funding, command structures, and legal frameworks) would be complex and contentious. (Yahoo News)

Expert Context

Evolving Strategic Landscape

Analysis from think tanks and defence experts suggests that Trump’s demands for increased NATO spending and a more assertive European role have catalysed debate on regional autonomy. Polls show other Europeans share scepticism about US reliability, with many believing their countries cannot currently defend themselves without US support. (La Voce di New York)

Commentary:
This isn’t isolated to the UK — wider European public opinion is tilting toward self-reliance in defence, potentially laying the groundwork for deeper continental cooperation. Critics urge caution, stressing that NATO and transatlantic ties remain critical to European security.

Summary of Key Points

Aspect	Insight
Public opinion in UK	Majority (55%) back a European defence pact without the US. (Yahoo News)
Primary driver	Fears that Trump’s US might not uphold NATO obligations. (Yahoo News)
Strategic backdrop	Russia’s threat and NATO spending demands accelerate debate. (The National)
Expert view	A pact is theoretically appealing but complex in practice. (Chatham House)

Final Commentary

This polling result represents a notable shift in British public thinking about defence and sovereignty. Rather than seeing the US as the automatic guarantor of security, many voters now favour closer defence cooperation with European partners — reflecting evolving geopolitical realities, anxieties over US policy under Trump, and a desire for Europe to play a more assertive role in its own defence. (Yahoo News)

Although a new defence pact remains aspirational, the public appetite for it could influence future UK and European security policy debates — especially as NATO, Russia, and transatlantic relations continue to evolve. (yougov.co.uk)
