The defense establishment loves a comfortable myth. Right now, the favorite bedtime story in Washington, London, and Brussels is that the return of peer-to-peer conflict means a permanent return to protracted, industrial-scale attrition wars. They look at artillery shell consumption rates in Eastern Europe, dust off historical volumes from 1916, and declare that the era of short wars is dead and buried.
They are entirely wrong.
Nuclear deterrence does not drag conflicts out into sluggish, multi-year trenches of mud and mass mobilization. It does the exact opposite. It creates an invisible, unyielding ceiling on escalation that forces states to win in weeks or lose everything. The lazy consensus assumes that because total war between nuclear-armed states is suicidal, any war between them must descend into a slow, agonizing war of attrition below the nuclear threshold.
That logic is backwards. When the stakes are total annihilation, neither side can afford a protracted stalemate that risks sliding out of control. The math of modern precision, cyber dominance, and strategic vulnerability means that the side which establishes dominance in the opening fortnight dictates the terms. Protracted war is a luxury reserved for actors who do not fear the apocalypse.
The Attrition Fallacy
Every time a think tank publishes another white paper comparing modern shell production to the steel mills of the First World War, an economist should weep. We are measuring twenty-first-century conflicts with nineteenth-century yardsticks.
I have watched defense procurement programs consume billions of dollars building massive stockpiles of heavy metal for a war that will never be fought the way planners expect. The argument goes like this: because modern high-intensity engagements chew through munitions at an unsustainable rate, supply chains will dictate a long war.
This ignores how high-tech capital assets function. Modern precision-guided munitions, advanced electronic warfare suites, and low-observable platforms cannot be churned out by rolling more steel plate off an assembly line. They require microchips, rare earth element supply chains, and highly specialized manufacturing ecosystems that take years to scale. If you run out of advanced interceptors on day thirty, you do not transition to a protracted war of industrial attrition; you fight with sticks and stones while the enemy holds total air supremacy.
A modern industrial base cannot sustain a high-intensity peer conflict for years because the inventory of high-end components is finite and fragile. The war will be decided by the inventory sitting in warehouses on day one, not the factory capacity that might come online in month eighteen. If your strategy relies on out-producing your rival in advanced electronics after the shooting starts, you have already lost.
Escalation Dominance and the Compressed Timeline
The core misunderstanding of nuclear deterrence is treating the bomb as a shield that permits endless conventional fighting underneath it. The Cold War gave us this distorted view through proxy conflicts in Vietnam or Afghanistan. But those were peripheries. When major powers clash directly or through vital proxies, the shadow of escalation changes the calculus entirely.
In a hyper-connected global economy, a protracted great power war destroys financial markets, supply lines, and domestic political stability long before the first trench is dug. Governments know this. The political tolerance for economic strangulation is near zero. Therefore, operational planners are not building doctrines for five-year campaigns; they are engineering decisive, lightning-fast campaigns designed to achieve strategic objectives before domestic populations panic and markets collapse.
Imagine a scenario where a regional conflict breaks out between major powers. Both capitals understand that every additional week of fighting exponentially increases the risk of a miscalculation triggering a strategic exchange. The incentive structure does not reward digging in. It rewards speed, shock, and surgical paralysis of command-and-control networks.
Wars are short now because they have to be. The moment a conflict threatens to drag on, the economic and political costs cross the threshold of unacceptability.
The Dangerous Obsession with Mass
Military theorists who pine for mass mobilization are suffering from historical nostalgia. They see large battalions on a map and feel a sense of security that contemporary technology simply does not support.
Mass without synchronization is just a target. A hundred thousand troops concentrated within range of modern sensor-to-shooter loops do not represent strength; they represent a high-priority cluster for precision strike munitions. The proliferation of commercial satellite imagery, synthetic aperture radar, and AI-driven targeting means that large formations cannot hide.
When everything can be seen, and everything that can be seen can be hit, concentration equals destruction. The future belongs to dispersed, highly autonomous units capable of hyper-local effects, not massive armies slugging it out across a static front. By clinging to the myth of the long war, defense ministries are funding the wrong capabilities, buying the wrong inventories, and preparing soldiers for a graveyard of obsolescence.
The Real Danger
The danger of believing in the inevitability of long wars is that it creates a self-fulfilling prophecy of unpreparedness. If you plan for a marathon, you pace yourself, hoard resources, and accept a grinding pace that invites escalation.
We need to stop planning for the war we find emotionally satisfying to study and start preparing for the brutal, compressed reality of modern statecraft. The next major conflict will be won or lost before the public even understands the full gravity of the crisis.
Stop waiting for the trenches to fill up. They won't.
