How Ukraineโs Successfully Waged War of Asymmetric Attrition Could Trigger Russiaโs Nuclear Escalation, and Collapse the Western Order.
The skies over Moscow, once an untouchable symbol of Russiaโs impenetrable imperial security, have become the Ukraine Warโs latest contested territory.
As Ukrainian drones routinely slip past Russian air defenses to strike at the heart of Vladimir Putinโs capital, the psychological, economic and strategic landscape of the war in Ukraine is undergoing a tectonic shift. It is a stunning display of asymmetrical ingenuity and a testament to Ukraineโs unbroken resolve four years into a brutal
But for those of us who study the grim calculus of international relations, realist theory, and nuclear strategy, this tactical triumph casts a profound existential shadow. We are edging precariously close to the terrifying reality that Bernard Brodieโthe founding father of modern nuclear strategyโrecognized at the dawn of the atomic age. We are re-entering a state of doom.
Fifteen years ago, in my 2011 book, State of Doom: Bernard Brodie, The Bomb, and the Birth of the Bipolar World, I explored how the advent of the absolute weapon fundamentally altered the nature of war and statecraft. Brodie famously observed in 1946 that, until the atomic bomb, the chief purpose of a military establishment was to win wars. “From now on,” he wrote, “its chief purpose must be to avert them.” For 80 years, this logic of deterrence has held firm. Nuclear weapons became the ultimate insurance policy against regime collapse and total state defeat, creating a stable, if terrifying, equilibrium among superpowers.
But what happens when that insurance policy is held by an authoritarian leader who launched a war of choice, only to find himself entangled in a humiliating, multi-year quagmireโand suffering more than one million casualties and counting?
As we navigate 2026, the conflict has evolved into a grinding war of attrition that has systematically bled Russian conventional forces. Now, with drones detonating in Moscow, the illusion of Russian invulnerability has been entirely shattered. The war is no longer a distant “special military operation” broadcast safely on state television; it is rattling the windows of the Kremlin.
From a classical realist perspective, a stateโs primary imperative is survival. However, in my research on the tribal foundations of world politics, I have often noted that beneath the veneer of the modern Westphalian state, older, primal loyalties dictate behaviorโrooted in an unyielding tribalism. Putinโs Russia has increasingly shed the trappings of a modern institutional state, reverting to an insular, tribal autocracy run by the its security elite (the siloviki). For this ruling clan, the survival of the Russian state and the survival of their regime are inextricably linked.
The drone strikes on Moscow are not measured strictly in military terms; they are profound political humiliations. They signal to the Russian elite and the public that Putin cannot protect his own stronghold. In the brutal logic of power politics, humiliation breeds desperation. And when the tribe’s inner-most sanctum is breached, the leadershipโs risk calculus can radically change.
This is precisely where the architecture of nuclear deterrence begins to buckle. Deterrence relies on rationalityโon the shared understanding that the costs of crossing the nuclear threshold outweigh any conceivable benefit. But rationality is subjective, bound by the specific pressures and fears of the decision-maker. If Putin believes that a conventional defeat in Ukraine, or the steady erosion of his domestic authority brought about by persistent strikes on the Russian homeland, will lead to his downfall, the unthinkable suddenly becomes thinkable. Using the bomb, of which Putin has so many, becomes a viable strategic option when their continued non-use could cause both military defeat and regime collapse.
The immediate fear has never been that Putin will launch a strategic first strike against Washington or London, triggering the near-certainty and totality of Mutual Assured Destruction (MAD). The far more chilling and realistic peril is the use of a non-strategic, or “tactical,” nuclear weapon within the Ukrainian theater. A low-yield detonationโperhaps over a military concentration, an infrastructure hub, or even as a demonstration over the Black Seaโwould serve a dual purpose for a desperate autocrat.
First, it would aim to reverse the fortunes of a failing conventional campaign, dramatically persuading Kyiv to compromise via the same unimaginable explosive shock that did the same for the unyielding Emperor of Japan eighty years earlier.
Second, it would test the ultimate resolve of the West. Putin may gamble that while NATO is willing to supply advanced conventional technology to maintain Ukrainian territorial integrity, it is not willing to risk Western capitals for Kyiv. Putin might calculate that a limited nuclear strike would paralyze the Western alliance with the fear of further annihilation.
Western analysts often comfort themselves with the assumption that a nuclear strike would turn Russia into a global pariah, completely alienating its remaining partners. But they may be dangerously wrong. In a fracturing global order, a successful, unpunished tactical nuclear strike could achieve the exact opposite of isolation: it would send a seismic shockwave through the international system, demonstrating that the West is ultimately a paper tiger when confronted by the Eastโs absolute resolve.
Rather than repelling Beijing, Tehran, or Pyongyang, such an unapologetic display of power might further unite the autocratic world around a newly dominant center of gravity. It could reinvigorate Russiaโs diplomatic leadership among revisionist states, positioning Moscow as the ultimate vanguard against Western hegemony.
This is the hidden trapdoor of the current crisis: the very real temptation that nuclear brinkmanship could pay off, rewriting the rules of global governance in favor of autocracy. Hence the temptation for Putin; hence the danger for us.
We are currently witnessing a volatile collision between the paradigms of modern conflict. Asymmetric, unconventional tactics are now colliding with the rigid, devastating power structures of traditional states. Ukraine has brilliantly exposed the hollow core of Russian conventional might, utilizing decentralized, high-tech drone warfare to outmaneuver a lumbering superpower. Yet, in doing so, it has inadvertently increased the utility of Russia’s unconventional, apocalyptic deterrent.
By bringing the pain of war to Moscow, Ukraine is effectively cornering the bear. And a cornered bear, armed with the world’s largest nuclear arsenal, could become the most dangerous actor in the international system.
Recognizing the danger of Putinโs nuclear temptation is not a call for appeasement; it is a prerequisite for survival. For years, the West has walked a geopolitical tightrope: arming Ukraine sufficiently to defend its sovereignty without provoking a Russian nuclear response. The drone strikes on Moscow represent a fraying of that tightrope.
Brodie warned us that the absolute weapon demands an absolute transformation in how we manage conflict. In this renewed state of doom, the ghosts of the Cold War have returned, armed with new anxieties and asymmetric triggers. As waves of drones continue to fly east toward Moscow, the distance between conventional humiliation and nuclear retaliation shrinks by the day.
We must tread ever carefully, for the absolute weapon forgives no miscalculation.
