Episode Title: Why Britain Is Saying No to Trump’s Iran War

Host: David Frum (The Atlantic)
Guest: Alastair Campbell (The Rest Is Politics; former aide to Tony Blair)
Date: March 18, 2026

Episode Overview

This episode explores the escalating conflict between the United States and Iran under President Donald Trump, focusing on the constitutional crisis the war is generating in the US. David Frum and guest Alastair Campbell analyze the growing rift between the US and the UK, driven by the British government’s refusal to support or participate in the US-led war against Iran. The conversation weaves in lessons from past US-UK military collaborations (especially Iraq), the role of international law and democracy, and Britain’s changed global position post-Brexit. The second half of the episode touches on the broader challenges of populism, the consequences of Brexit, concerns about the future of Western alliances, and the enduring importance of constitutional democracy.

Key Discussion Points & Insights

1. Constitutional Crisis: The Iran War & Congress’ Role

• Frum questions the legality and constitutionality of the ongoing US war against Iran, emphasizing its lack of Congressional authorization.
  • Most major US engagements post-1945 (Korea, Vietnam, Iraq, Afghanistan, ISIS, etc.) had either explicit Congressional/treaty authorization or were limited in scope.
  • The Iran war stands out for being major, costly, and entirely unapproved by Congress.
    • [07:44] “This is like parking an airplane in midair. You cannot stop this war right now… This war will have to be fought to some kind of resolution… That makes the absence of congressional authorization even more glaring.” – Frum
• Congress’ complicity: Many in Congress quietly support the war but avoid a vote to sidestep political risks, leaving oversight to the executive.
  • [10:38] “Many in Congress… support the goals of this war… but don’t trust Donald Trump, don’t want to tangle with the progressive wing… and prefer not to cast a vote.” – Frum

Key Quotes

• [11:49] “No emoluments, no atrocities. They have to be present. And that means they need some kind of oversight structure.” – Frum

2. US-UK Alliance Under Strain

• Campbell explains the UK’s refusal to participate in Trump's Iran war:
  • PM Keir Starmer, an international lawyer, found no legal basis for UK involvement and restricted American use of UK bases.
  • Trump reacted with public disparagement, accusing Britain of unreliability and launching personal attacks on Starmer and London’s mayor.
    • [13:52] “Keir Starmer… decided that he could see no UK legal base for taking part in the attack on Iran and therefore did not allow the Americans to use some of our bases.” – Campbell
    • [14:42] “Trump… saying that Britain was unreliable. Keir Starmer’s no Winston Churchill. And then going on for this Nth time, this MAGA ridiculous attack on London…” – Campbell
• Frum recounts Trump’s series of economic and military affronts against UK and Europe post-2025: tariffs, disparaging veterans, and conflicts over base rights in Diego Garcia and Greenland.
  • The UK’s sovereignty over Diego Garcia and the Chagos Islands called into question; Starmer blocking US operations there.
• Both agree Trump’s presidency has deeply personalized—and weaponized—the “special relationship.”
  • [19:23] “The politics… is defined around the personality of one human being, namely Donald Trump and what he thinks he is entitled to…” – Campbell
  • [21:15] Frum notes the shift of "special relationship" away from the UK if British military power continues to wane.

Notable UK Positions

• UK right-wing media and populists support Trump and criticize Labour, despite their usual rhetoric about foreign influence.
  • [19:58] “These are the same people who… want to bow down before, surely one of the most unhinged, dangerous American presidents…” – Campbell

3. International Law, Sovereignty & Moral Dilemmas

• The UK government’s legalistic, measured approach to international law (e.g., Chagos Islands, refusal to join Iran war) is presented as a principled stand—but it is also criticized as constraining only Western democracies.
  • [25:00] “Britain… has got itself committed to a vision of international law that is so tangled and so one sided that it constrains democracies. It doesn't constrain non-democracies.” – Frum
• Campbell warns that international law is fundamentally politicized; decisions faced by the UK are frequently weaponized by domestic and international actors.

4. Lessons from the Iraq War: The “What Happens After?” Problem

• Both reflect on the mistakes of the Iraq invasion, particularly the lack of post-war planning and realism about outcomes, and their application to Iran.
  • [30:03] “If there’s something that we didn’t ask enough, it was about what happens after.” – Campbell
  • [32:02] “The lack of plan really is alarming… It was a point of principle almost to refuse to think about what happened next…” – Frum
• Both criticize the Trump admin for “doubling down” on not planning for the aftermath of regime change in Iran, with Campbell calling Trump’s approach “the reality TV show” model of foreign policy.
  • [34:02] “He gives them all a personality and… this is kind of sort of good v. evil… There’s never been a successful regime change from the air.” – Campbell

5. Domestic Risks & Authoritarian Drift

• Frum raises alarm over Trump potentially leveraging war powers to curtail civil liberties, especially with Homeland Security defunded and threats of military involvement in US elections.
  • [37:09] “You have to prudently assume [Iran] have some [terror capacity]. Right now… a blockade by Democrats in Congress against funding the Department of Homeland Security… as Americans rightly worry that the Iranians may strike back on the American homeland… Trump is going to reacquire the powers that he so terribly misused…” – Frum
• Campbell warns that the distraction and chaos wrought by conflict could be exploited to further erode democratic norms—including postponing US elections.

6. The Brexit Catastrophe and British Isolation

• The UK’s “act of self-harm”—leaving the EU—has left Britain isolated strategically and economically.
  • [44:34] “My answer is no, we haven’t [adjusted to isolation]… it’s the worst act of self harm… Our economy is probably about, you can pick your reports and take your pick, but we’re probably 5% weaker than we were.” – Campbell
• Trump’s role in pushing the UK toward a maximalist, US-centered Brexit is highlighted, as well as the US’s subsequent renege on promises.
  • [46:18] “Throughout that period, Donald Trump… was saying, if Britain agrees… we’re going to cut them a wonderful deal for a free trade deal with the United States. Now… Nothing has come of it all this decade later.” – Frum

7. Populism, Polarization & The Future of the Western Alliance

• Campbell bemoans the post-truth, propagandistic age and the ease with which populists like Trump, Farage, and others manipulate public sentiment—even as their policies damage Western solidarity.
  • [47:47] “Meanwhile, the reality of Brexit is a weaker economy, a weaker country… a country that feels pretty isolated in very, very dangerous times.” – Campbell
• Frum asks if the rise in Russian and Chinese assertiveness could rekindle European unity; Campbell is cautious, noting continued volatility, ongoing populist appeal, and challenges such as migration.

8. Are Britain or Europe at Risk of Authoritarian Takeover?

• Campbell is not convinced the UK is about to go “hard right,” but describes political volatility and the general media environment as worrying.
  • [54:23] “I think we’ve hit peak Farage… Trump is a uniquely unpopular figure in Europe right now… But… I wouldn’t put my life on anything right now.” – Campbell

• Post-Brexit, Britain is more isolated and vulnerable, with its “special relationship” with the US largely illusory.
