Introduction

GLENN DIESEN: Hi, everyone, and welcome back. My name is Glenn Diesen, and I’m joined today by John Mearsheimer and Alexander Mercouris to discuss these developments in the Ukraine proxy war. So it’s good to see you both again, and I guess there’s a lot to discuss.

Trump began his presidency by recognizing three main criteria: no NATO, accept territorial concessions, and there will be no American security guarantees, which is more or less what Russia had demanded. I guess why the three of us were a bit optimistic at the time, but then he went back to the unconditional ceasefire, which means not actually addressing any of the things that Russia demanded.

And now there’s been this sudden return or at least seemingly a return to no NATO, some territorial concessions, yet a lot of ambiguity what exactly security guarantees would entail. So I’m very interested to hear what the two of you make of this. John, why don’t you start?

The Security Guarantees Confusion

JOHN MEARSHEIMER: I’ll say this. I mean, I think that this whole idea of security guarantees came out of discussions that he had with Putin in which clearly they did discuss the security situation in Europe and in Ukraine. And this is where I’m starting to get concerned because it was then taken away from that meeting in Alaska as if the Russians had agreed to security guarantees, which I don’t think they have, at least not in the sense that they’re being talked about in Europe now and by Trump himself.

Trump sometimes gives the impression that he’s giving security guarantees to Ukraine on behalf of the United States. Then he pulls back on that. Then one moment he talks no troops on the ground, then he floats the idea of the United States playing some kind of a role in terms of air power and all of that. Then we are back to talking about sending European troops to Ukraine and the Europeans giving security guarantees, but supported in this by the United States.

ALEXANDER MERCOURIS: The Russian foreign minister Sergei Lavrov has now made quite clear over the course of an interview that the Russians are not in agreement with any of this. There were security guarantees negotiated between the Russians and the Ukrainians back in April 2022 as part of the Istanbul agreement.

I think the word “guarantee,” by the way, is altogether too strong. There were some kind of security assurances. There was going to be a collection of countries that were going to say that Ukraine should be protected within its own territory at the end of the war. One of those countries was going to be Russia. The European countries and the United States would be those countries, other countries as well.

China was going to be yet another country. And there were other countries, including, as I remember, Israel and several others that were also going to provide these security guarantees.

The Istanbul Agreement Framework

ALEXANDER MERCOURIS: The security guarantees envisaged that there would be no foreign troops on Ukrainian territory and no deployments even on a temporary basis of foreign troops on Ukrainian territory without the agreement of each of the guarantors, which would have given the Russians veto power over any deployments of any kind of foreign troops in Ukraine. All of this in the context of an agreement, which also envisaged very tight restrictions on the size of Ukraine’s armed forces.

Now I suspect this is what the Russians have in mind or had in mind when this whole idea of protecting Ukraine’s security was first brought up with them. What we’re now hearing people talking about in Europe and to some extent in the United States is something completely different, which goes far beyond what the Russians were talking about and which looks like some kind of alliance between the western powers and Ukraine even if Ukraine for a temporary period remains outside NATO.

And, of course, that for the Russians is completely unacceptable. And, as I said, Lavrov again made that, I think, fairly clear in the interview that he gave yesterday. So there is complete cross purposes about this.

Telling Each Side What They Want to Hear

ALEXANDER MERCOURIS: I’m not sure whether perhaps the Americans misunderstood the Russians, but I have to say altogether, I do wonder whether perhaps the Americans in their anxiety to get this process of negotiations going are telling every side what they think they want to hear.

So they’re telling the Russians and, again, Lavrov clearly came away with the impression from Alaska or says that he came away with the impression from Alaska that the Americans were willing to discuss the entire security architecture of Europe, which I cannot genuinely believe the Americans do. And the Europeans are being told that there’s security guarantees on the table and that the Russians are happy with that. And, again, clearly, from what the Russians are saying, they are not.

And I think that this is dangerous because if you’re telling each side what they want to hear, the risk is that when they all come together and we do actually have a meeting, if it ever happens, we will find that everybody comes into that meeting with contradictory expectations. And at that point, the whole thing could just fall apart with leaving us in an even worse position than the one we’re in now.

Who’s Driving the Security Guarantees Discussion?

JOHN MEARSHEIMER: Well, I think the big question in my mind to start with is who’s driving the train here? Where’s all this discussion about security guarantees coming from? And in my opinion, it’s coming from the Ukrainians and the Europeans. They talk relentlessly about security guarantees.

And the reason is very simple. Not only did they want to defend Ukraine moving forward, they want to keep the Americans in Europe.
