Transcript of Boris Johnson Interview on School of War Podcast

The following is the full transcript of former British Prime Minister Boris Johnson’s interview on School of War Podcast, August 11, 2026.  

EDITOR’S NOTES: In this episode of the School of War Podcast, former British Prime Minister Boris Johnson joins the conversation as the war in Ukraine enters its fifth year and strains on the transatlantic alliance deepen. He argues that the West still holds the power to prevail—insisting “Putin has got to lose”—while explaining how to pressure Russia to the negotiating table, dismissing Europe’s pursuit of “strategic autonomy” as a sham, and challenging the narrative of American decline in favor of continued U.S. leadership.  

INTRODUCTION

AARON MACLEAN: Today on School of War, we talk to Boris Johnson, who was Prime Minister of the United Kingdom from 2019 to 2022, a period that saw Brexit, the Russian invasion of Ukraine, and much more besides. We’ll talk about Ukraine, his experiences there recently, but also his leadership back in 2022, elements of which were quite controversial. We’ll talk about the Atlantic relationship between the United States, the UK, and Europe. European complaints about President Trump, American complaints about the Brits. Things get a little bristly at times. Let’s get into it.

AARON MACLEAN: Hi, I’m Aaron Maclean. Thanks for joining School of War. I am delighted to welcome to the show today Boris Johnson, once Prime Minister of the United Kingdom. He’s been twice Mayor of London, the Foreign Secretary, leader of the Conservative Party, led Britain through a tumultuous period of Brexit, COVID, and the Russian full-scale invasion of Ukraine. Thank you so much, sir, for coming on the show.

BORIS JOHNSON: Pleasure. Nice to see you.

The Road to War

AARON MACLEAN: Let’s start with Ukraine. I know you travel there frequently, and I want to get to where we are and the road ahead. But before we do that, I want to take you back to 2021, 2022, when you were in office.

BORIS JOHNSON: Yeah.

AARON MACLEAN: And just talk through those events, because I think it will be very interesting to listeners and viewers. Do you remember when you first realized that the invasion was going to happen, that it was real?

BORIS JOHNSON: Well, it’s a very good question, because I’ve got to pay tribute to my defense secretary, a guy called Ben Wallace. Back in the summer of ’21, he read Putin’s crazy Nostradamus essay about how Ukraine is part of Russia, all this nonsense. He came to me and said, look, I really think he’s serious. I really think he’s going to invade.

So over that autumn, I read it too, and I could see that something very nasty was going to happen. We decided to see what we could do to help, because we’d been helping Ukraine for a long time, since the first invasion in 2014. The UK was always very heavily pro-Ukraine, trying to keep Putin under control and back the Ukrainians.

To answer your question — when did we know? By the end of ’21, beginning of ’22, we had very little doubt. To be frank, the SIGINT and the intelligence we were getting from your guys, our guys — it was overwhelming. We knew he was planning something very bad.

The funny thing was that we couldn’t convince our best friends. We couldn’t convince the French. We couldn’t convince the Germans — maybe because they had so much emotionally invested in the idea that this wasn’t going to happen. Even on the eve of war, it still wasn’t clear to them. I remember in February 2022 going to Ukraine, just before the invasion, talking to Volodymyr Zelensky. Even then, he was being ambiguous about whether he thought it was actually going to happen. But that was because he didn’t want to scare people in his own country. I think he knew it was going to happen.

So I would say turn of the year ’21, beginning of ’22 — certainly by the Munich Security Conference — we were pretty sure.

AARON MACLEAN: And British policy was really leaning into the prospect of this invasion. You supplied anti-tank weapons to the Ukrainians quite early on in 2022.

BORIS JOHNSON: To be fair, don’t forget — we did. I’m very proud of what we did. We sent them something called NLAWs, a very useful anti-tank shoulder-launch weapon made in Belfast by what was Short Brothers, now Thales. But the credit for really breaking the taboo on sending important lethal weaponry belongs to Trump. I can’t remember exactly who — maybe it was John Bolton or somebody who told him — but he sent them the Javelins.

AARON MACLEAN: Yeah.

BORIS JOHNSON: Fantastic thing to do.

AARON MACLEAN: Yeah, it was in that era.

BORIS JOHNSON: I think it was. And that made a real difference — it enabled us to do it and to make the case to our friends.

European Skepticism

AARON MACLEAN: Do you remember, on the other side of the ledger, speaking to folks who were skeptics? Because there were a lot of skeptics right up to essentially the moment of the invasion that it was actually going to happen. Do you remember conversations you had, perhaps with Macron or others, where they expressed skepticism that this was going to come? What was the nature of European skepticism? I think it was a desperate hope that it wouldn’t come.

BORIS JOHNSON: Wasn’t going to come, and I was saying, come on, we’ve got to put sanctions on these guys to stop them doing it. I remember Olaf — the German guy — was very much against that. Emmanuel too.

If you remember what happened with the Ukraine dossier — from 2014 onwards, we basically messed up the Normandy commemorations, I think it was in July. We hadn’t been at the right meeting. The Normandy format was France, Germany, Russia, and Ukraine, treating the conflict as though it was a domestic dispute between Russia and Ukraine.
