John Mearsheimer: Ukraine Is Landlocked & Donbas Enters Endgame (Transcript)

Read the full transcript of political scientist Professor John Mearsheimer’s interview on Greater Eurasia Podcast, July 30, 2026.

Episode Notes: In this interview, political scientist Professor John Mearsheimer joins host Glenn Diesen to examine the latest developments in the Ukraine war. Mearsheimer discusses how Ukrainian drone strikes on Russian targets, conducted with NATO support, prompted a strong Russian response that has effectively rendered Ukraine landlocked by closing its Black Sea ports. The conversation critiques prevailing Western narratives about the conflict’s progress, analyzes the deteriorating situation on the Donbas front, and explores Ukraine’s mounting manpower, economic, and political challenges. Together they consider the broader strategic implications, the limits of escalation, and potential paths toward a negotiated outcome.

Ukraine’s Drone Campaign and Its Consequences

GLENN DIESEN: Welcome back, everyone. Today is July 30th, 2026, and Professor John Mearsheimer joins us to try to make some sense of the world. So thank you for coming back on.

JOHN MEARSHEIMER: My pleasure, Glenn, and I’ll do my best, although it’s a very difficult task at this point in time, as you well know.

GLENN DIESEN: Yes, I agree. No matter where we look, things just appear to be getting more crazy. I wanted to start a bit with what has been celebrated so very widely in the West, which are these new attacks by Ukraine into Russia, with what appears, of course, to have extensive support from NATO.

They’re hitting deep inside Russia, but instead of just going after refineries, they’re also now — the main big targets are these warehouses owned by Wildberries, this e-commerce giant. And essentially the claim one gets is that by hitting civilian targets, it will not only hurt the economy, but it will also make Russian civilians feel the war themselves. And as a result, it would put more pressure on the Kremlin. And I was wondering how you assess this strategy and the assumptions it’s based upon.

JOHN MEARSHEIMER: Well, I think that there’s no question that these Ukrainian attacks caused the Russians problems. I think the results that you just described are true. People will be unhappy and they’ll put pressure on the government to do something about that. But there are two big questions you then have to ask yourself. What will the Russian government do, number one? And number two, what effect will these Ukrainian long-range drone attacks have on the outcome of the war? Those are the two questions you have to ask yourself.

Well, to start with the first question, the end result of this campaign is that it has caused Putin to wage the war more aggressively against Ukraine. And most importantly, the Russians have shut down the Odessa port complex on the Black Sea, and they’ve shut down all of the Ukrainian ports on the Black Sea, which effectively means that Ukraine is now a landlocked country. This is disastrous for Ukraine.

Before the war started, about 90% of Ukrainian exports went through the Odessa ports. 90%. And no, I take that back. 90% of the agricultural goods went through Odessa and about 70% of the overall exports went through Odessa. These are remarkable numbers.

You remember the Russians shut down Odessa, they shut down the Black Sea between February 24th, 2022, when the war started, and July, a few months later. And during that February to July 2022 window, the Russians caused enormous damage to the Ukrainian economy. And fortunately for Ukraine, a deal was worked out under the auspices of the UN and Turkey that led to the reopening of the port, or the ports, in the Odessa area in July of 2022. That was manna from heaven for the Ukrainians.

Well, fast forward to the present. What the Russians have done is they’ve shut down the Odessa port complex. They’ve shut down all of the Ukrainian ports on the Black Sea. This is going to have devastating economic consequences. And it’s not like Ukraine is a country that is in good economic shape at this point anyway. In fact, enormous damage has been done to the Ukrainian economy over the course of this war. And this will just make a horrible situation much worse.

So there’s no question that the Ukrainian long-range drone campaign has inflicted pain and caused problems for the Russians. No doubt about that. But the Russians have retaliated and they are able to cause much more pain for the Ukrainians than the Ukrainians can cause for the Russians. So this escalation does not work to Ukraine’s advantage. In fact, I would argue it works to Russia’s advantage. And I often wonder why the Russians didn’t shut down the Odessa port complex earlier. Why did they wait so long? Well, thankfully, the Ukrainians have prompted Putin to do it now.

So to get to my second question, this is not going to improve Ukraine’s prospects of winning the war. In fact, this is going to work to Ukraine’s disadvantage. And by the way, it’s not just the shutting down of Ukraine’s ports on the Black Sea that matter here. The fact is, if you look at what the Russian air offensive against Ukraine is doing, it’s also targeting all sorts of infrastructure, all sorts of places where drones and military equipment is produced inside of Ukraine. It’s shutting down gas stations all across eastern Ukraine, making it almost impossible for a vehicle to drive from point A to point B because there’s no gas available. The Russians are targeting railroads and locomotives and so forth and so on.

So the end result of this air campaign that the Russians are now escalating because of what Ukraine is doing is to speed up the process of Ukrainian defeat. So I think there’s no question that Russia will suffer some pain, but in the end, the Ukrainians will suffer more pain, and it will speed up Ukraine’s defeat.

Ukraine Becomes Landlocked: Strategic and Economic Fallout

GLENN DIESEN: I guess the whole logic of increasing the pain on Russia, hoping that they will somehow capitulate, it doesn’t — it seems to be flawed for the same reason that measuring success in terms of death and destruction is — yeah, it’s the same flaw.
