A Front Line Frozen by Drones

Malik said the front line has barely moved in nearly five years. Drones have extended the “kill zone” to as much as 50 miles, and Ukraine is turning to unmanned ground vehicles (UGVs) that commanders believe could replace up to 60% of frontline infantry. By his estimate, Ukraine needs about 500,000 a year and currently produces roughly 20,000. Each of Ukraine’s more than 100 combat brigades now has an unmanned battalion, he said, and those units account for about 80% of Russian casualties.

Cheaper Weapons, Changing Math

Cost is central to that shift. Malik said a Shahed-type attack drone costs between $50,000 and $150,000, while a fighter jet starts around $15 million and a Patriot missile can cost up to $4 million, which makes conventional air defense unsustainable against mass drone attacks. Ukraine answered with its own interceptor drones, he said, and builds a drone-missile hybrid called Flamingo at an unofficial cost of about $600,000, compared with $1.5 million or more for a Tomahawk. A high-intensity war, he argued, is won with cheap systems that can be made in large numbers, not with a few hundred advanced aircraft, and Ukraine’s private defense firms are finding new battlefield uses for the technology nearly every month.

The constraint, both speakers said, is money more than ingenuity. Ukraine spends about 40% of its GDP on defense, compared with roughly 10% in Russia, and 3.5% in the U.S. Vacroux urged Europe to disburse a promised €90 billion loan faster and to resolve the impasse over frozen Russian assets.

A War the World Is Watching

The speakers noted that Ukraine’s rivals are studying the war more closely than its partners. Malik said North Korea has supplied ballistic missiles and soldiers to Russia, and Vacroux said the country is bringing that experience home for a possible fight with South Korea. China, she said, is doing the same as it thinks about Taiwan. The Americans and Europeans, by contrast, are mostly not gaining firsthand experience, and cutting off Ukrainian partnerships cuts off the chance to learn without sending their own troops into that kind of war. Malik predicted that U.S. forces will soon face jet-powered Shaheds in the Middle East, and said neither the United States nor Europe has an affordable way to stop them at scale.

Pressure on Russia, and on Europe

Vacroux said sanctions and Ukrainian strikes on refineries are straining Russia’s economy, though economic pressure alone is “necessary but not sufficient” to end the war. She also described a rise in Russian sub-threshold attacks on Europe, including cyberattacks, arson and drone incursions, which she said test the credibility of NATO’s Article 5.

Peace Talks, Nuclear Threats, and the Will to Keep Fighting

When asked about negotiations, Malik was blunt. “Negotiations are one very big myth,” he said. Vacroux noted that some channels still produce prisoner exchanges. Both viewed Russian nuclear threats as deterrence more than intent. Vacroux said about three-quarters of Ukrainians want elections to wait until the war ends, and 62% say they will keep fighting “as long as it takes.” Malik expected another wave of residents to leave Kyiv this winter.

Vacroux closed by sharing her belief that Ukraine’s only dependable security guarantee is the one it builds itself. “It cannot rely on the United States. It cannot rely on companies like Starlink. It cannot rely on the Europeans.”

Introduction and Contribution:

The ongoing Russo-Ukrainian War has been one of the most devastating conflicts of the 21st century. Since Russia’s 2022 invasion, Ukraine has experienced not only mass casualties but immense cultural destruction, as well as the forcible deportation and adoption of thousands of Ukrainian children to Russian families. Ending the war requires understanding its causes, particularly from the point of view of Vladimir Putin and other key Russian decision-makers. 

Some observers of Russian and global politics — as well as Putin and his allies — have claimed that the prospect of Ukraine joining NATO caused the war. The argument here is that as a superpower, Russia could not tolerate the security implications of a country on its border joining a rival alliance. Russia’s war, then, was a preventive one — less a choice than a strategic necessity. Any superpower in such a situation would do the same.

In “NATO Did Not Cause Putin’s Imperial War,” James Goldgeier and Brian D. Taylor convincingly challenge the NATO hypothesis, showing it to be more a piece of Kremlin propaganda than a plausible account of Putin’s decision-making process. Instead, the authors draw our attention to Putin’s most deeply held and longstanding beliefs: that Ukraine is not a legitimate nation state, that Ukrainians would not freely associate with the West and its alliances (unless they were being manipulated), and that dominating Ukraine is essential to Russia reclaiming its status as a global superpower, one that is constantly disrespected by the West. 

As many social scientists focus on improving the causal power of their statistical inferences, Goldgeier and Taylor helpfully focus our attention on the beliefs and reasons of political actors who cause political outcomes such as wars and revolutions. More importantly, the authors provide a starting point for thinking about ending the Russo-Ukrainian war, one focused not on the distraction that is NATO arguments but on Putin’s imperial ambitions.

Pitfalls of the NATO Explanation:

The authors begin by noting that NATO enlargement clearly played a role in the deterioration of relations between Russia and the West over the past 25 years. In part, this is because many Russian elites — owing to their imperialistic beliefs, more on this below — never accepted that former Soviet Republics were free to join the alliance. However, NATO enlargement was but one item in a long list of Russian grievances, some based in reality and others fictional. These include the 2003-04 Color Revolutions — mainly reflecting widespread domestic sentiment, not Western machinations — and alleged American support for the 2011-13 Russian protests in the aftermath of Putin’s rigged elections, which were similarly homegrown.

There is good evidence that Putin and his inner circle neither feared NATO aggression nor believed that Ukraine could realistically join the alliance. After George W. Bush’s failed bid for Ukrainian membership in 2008, no American president has seriously entertained or pushed for Ukraine’s admission. NATO took minimal action after Russia’s 2014 invasion of Ukraine, before which time Ukrainians themselves didn’t support joining the alliance (likely because they anticipated the negative consequences for Russia-Ukraine relations). NATO itself has worked against admitting Ukraine; indeed, much of its security assistance has been designed to make it possible for Ukraine to defend itself without formal admission. What’s more, no country bordering Russia joined NATO after 2004 until Finland did so in 2023.

When Putin decided on war in 2021, his invasion plan was based on the assumption that victory would be quick and easy, evidencing his lack of concern for NATO intervention. Further, he knew that NATO lacked the troops and would be extremely wary of confronting nuclear Russia. 

Putin’s Imperial Beliefs and Goals:

For several decades, Putin has expressed the belief that Ukraine is not a genuine nation-state and that Russia both gave away and was “robbed” of much of its territory. One of Putin’s key goals is arguably to rebuild Russian greatness via imperial conquest. The West is not merely intervening in Eastern European politics but, according to Putin, actively working to downgrade Russia to a second-class country and undermine its sovereignty. Putin views the war as key to reversing Russia’s declining status.

Because Putin and his inner circle view Ukraine to be a natural part of Russia, the possibility that Ukrainians would freely tie their fortunes to the West is inconceivable — Ukrainian elites must have been tricked, co-opted, or bribed. Some Russian propagandists have even described the war as one of “Russians killing Russians.”

Putin’s imperialism is not only confined to privately held beliefs. During COVID-19, he spent a great deal of time reading historical texts to prepare a 5000-word article on the alleged historic inseparability of Russia and Ukraine. What could such an undertaking have to do with NATO expansion?

Russia’s wartime conduct also provides strong evidence for the imperialism explanation. As mentioned above, Russia has gone to great lengths to destroy Ukrainian culture. It has rejected multiple peace deals that would have prevented Ukraine from joining NATO. Putin saw these as failing to address the conflict’s “root causes,” arguably a euphemism for Ukrainian sovereignty. Instead, Russian conditions for peace include making Russian an official language, disbanding “nationalist” political parties, and ensuring the influence of Moscow’s Orthodox Church. These conditions smack of Russian chauvinism.

Of course, elites’ imperial beliefs do not necessarily lead to war. And indeed, Putin initially sought to control Ukraine through political measures, such as election interference. However, the authors argue that when President Volodymyr Zelenskyy seized the assets of a key Putin ally, Putin realized his position was weakening. Russian security officials then assured Putin — likely out of fear — that overthrowing Ukraine’s government would be easy. This flawed decision-making process led to war. Readers will come away struck by how many lives have been lost while policy and scholarly debates remained focused on the NATO hypothesis.

*Brief prepared by Adam Fefer.

For Oleksii Movchan, a member of the Verkhovna Rada (Ukraine’s Parliament) and deputy chair of the parliamentary committee on economic development, his focus is on expanding financing tools for reconstruction. As part of a project he began during his 2025 SU-DD fellowship, he is drafting legislation to reform municipal bond regulations, aimed at increasing the participation of local governments in securities and debt markets and attracting additional resources for rebuilding Ukraine. To accomplish this work, he has relied on the Problem-Solving Framework he learned at Stanford, and shares that his experience in the SU-DD program made him more confident in his values and encouraged him to “stand on [his] principles and values of integrity, openness, and respect to human rights and democracy.” By strengthening municipal access to capital, his work seeks to support infrastructure recovery while reinforcing transparent financial governance.

Maria Golub, a senior political and policy advisor working on EU and NATO integration, is developing a national Coalition for Recovery — an inclusive, cross-sectoral platform designed to unify Ukraine’s defense, reconstruction, and reform agendas. With Ukraine balancing the demands of war and reconstruction, Golub’s 2025 SU-DD project aims to ensure that recovery planning connects security, governance, and innovation rather than treating them as separate tracks. Currently in a pilot, her proposals have already informed the government's 2026 recovery and resilience planning process.

At the regional level, Mykhailo Pavliuk, vice-chairman of the Chernivtsi Oblast (state) legislature in Ukraine, is actively implementing reforms to advance self-government and deepen Ukraine’s decentralization process. His work, initiated during his time at Stanford in 2023, focuses on strengthening “consolidated, self-sufficient communities” by developing political, financial, infrastructure, and social strategies that can be carried out locally, including cross-border regional initiatives in Chernivtsi. He said the most important element is “supporting the potential of people at the local level through the activities of advisory bodies, consultations, and modeling of joint decisions,” bringing citizens closer to decision-making on community affairs. Pavliuk emphasized that decentralization has been critical to Ukraine’s resilience since 2022, while noting that “there would certainly be a greater outcome in peacetime,” without the constraints imposed by war.

In the media sector, Alyona Nevmerzhytska, CEO of the independent outlet hromadske, is actively implementing her 2025 SU-DD project to strengthen the organization’s long-term sustainability and resilience. Her work, she says, “addresses two interconnected challenges: financial vulnerability and the rapid emergence of AI in the media landscape.” By developing diversified revenue strategies and integrating responsible AI tools into newsroom workflows, she aims to “improve efficiency, counter disinformation, and expand audience reach.” Despite ongoing security risks, she shares that the newsroom has maintained consistent production, adapted its operations, and prioritized staff safety, demonstrating what she described as “strong institutional resilience.” During her time on campus, Nevmerzhytska met with Stanford journalism and technology experts, whose guidance enhanced her strategic thinking around AI integration and digital modernization, “providing practical insights and [the] confidence to adopt responsible AI tools for efficiency and multilingual production.” She reports that hromadske continues to serve as a platform for accountability and public debate, reinforcing its role within Ukraine’s civil society.

Iaroslav Liubchenko, currently CEO of Ukraine’s national electronic public procurement system Prozorro, focused his 2023 Stanford project on strengthening transparency, efficiency, and institutional integrity in Ukraine’s defense procurement architecture. Today, that vision has become central to his leadership agenda. Prozorro is advancing three core priorities: deepening European integration through the approximation of EU public procurement directives into national legislation — in cooperation with Member of Parliament Oleksii Movchan — and sharing Prozorro’s digital governance model with EU partners; scaling up defense procurement within the system, including drones, unmanned and robotic systems, electronic warfare capabilities, non-lethal equipment for military infrastructure, and strengthened cooperation with the Defence Procurement Agency; and developing the broader Prozorro ecosystem through new coalitions and markets, advanced digital instruments, and AI integration. Prozorro seeks to ensure that Ukraine’s defense and rebuilding efforts are supported by transparent, technology-driven, and institutionally resilient procurement systems — not only fully aligned with EU standards, but capable of serving as a model for public procurement reform across Europe.

Ukraine’s Path Forward

Together, the fellows describe a future shaped not only by physical rebuilding but by the strength of Ukraine’s institutions and civic life. When asked about the country’s priorities for the next several years, their responses aligned in three areas: securing victory and sustaining defense capacity, advancing EU integration, and rebuilding critical infrastructure. Each emphasized that reconstruction must be paired with governance reforms to ensure public trust and long-term resilience.

Amid the political, economic, and human toll of war, our fellows agreed that the “unbreakable spirit and will of Ukrainians” gives them hope. “I am inspired by the endurance of Ukrainian society,” said Nevmerzhytska. “Despite exhaustion and loss, people continue to volunteer, innovate, and support each other. That civic resilience gives me confidence that Ukraine’s democratic spirit remains strong.”

As we look to the beginning of the fifth year of Russia’s war, Ukraine’s future is still uncertain. But the projects these leaders developed during their time at Stanford have carried into their work in parliament, regional government, civil society, media, and the defense sector. What began as ideas for reform are now being tested and adapted under wartime conditions, as they work to keep institutions functioning and prepare for the country’s long-term recovery.
