The age of strategic comfort is over

In July 2025, the United States quietly paused weapons shipments to Ukraine. Patriot interceptors, 155-millimetre artillery shells, precision rockets, Hellfire missiles, the consumables of high-intensity war, were held back because American stockpiles had fallen too low. The world's largest military power, spending more on defence than the next ten nations combined, could not simultaneously sustain one ally in a single-theatre land war and maintain its own readiness. That is the world Australia lives in now. The question is whether Australians have understood what it means.

It means that the age of strategic comfort is over. The assumptions on which Australian security was built for three decades, that major war was remote, that allies would always have capacity to spare, that maritime trade would flow without serious interruption, that economic interdependence would restrain revisionist powers, have been overtaken by events. Wars expected to be short have dragged into years. Allies expected to be inexhaustible have discovered the limits of their own arsenals. Trade routes treated as permanently open have been shut by militias with cheap missiles and drones. Coercion, economic, maritime, and diplomatic, has become a routine instrument of statecraft, applied not as a prelude to war but as a substitute for it.

For Australia, this is not abstract. This is a country that holds fifty days of fuel reserves against a ninety-day international obligation. A country whose permanent military numbers barely sixty-one thousand. A country whose major defence projects run, on average, twenty-five months behind schedule. A country that has issued the right strategic assessments, the 2023 Defence Strategic Review, the 2024 National Defence Strategy, with their language of deteriorating conditions and reduced warning times, and then continued operating as though the old world were still intact. Australia has diagnosed the illness. It has not begun the treatment.

Australia has diagnosed the illness. It has not begun the treatment.

This essay sets out the world as it exists in 2026. It is a world of protracted wars, strained alliances, contested sea lanes, and coercion below the threshold of open conflict. Understanding it honestly is the precondition for everything that follows.

The long war

The war in Ukraine has entered its fifth year. That fact alone should force a recalibration of strategic thinking in every Western capital. When Russia launched its full-scale invasion in February 2022, a great many officials and analysts expected the war to be resolved, one way or another, within months. The American intelligence assessment in the opening week gave Kyiv seventy-two hours. Five years later, Ukraine is still fighting, still absorbing punishment on an industrial scale, and still dependent on external support that has proven more brittle, more conditional, and more politically mediated than the language of allied solidarity ever suggested.

The strategic lesson is about the character of modern war itself. Wars between substantial powers, once begun, resist quick endings. They grind through ammunition stockpiles that took decades to accumulate. They expose industrial depth that cannot be improvised after the shooting starts. And they test the coalitions behind the combatants in ways that peacetime commitments never anticipated. Coalition support, it turns out, is not a standing reservoir of shared purpose. It is a negotiation conducted under pressure, shaped by domestic politics, fiscal constraints, and competing priorities that shift faster than the battlefield.

The ammunition crisis made this concrete. By 2024, European arsenals had been drawn down to the point where several NATO members were publicly acknowledging that their own war reserves had fallen below acceptable levels. The European Union's plan to deliver one million 155-millimetre shells to Ukraine by March 2024 fell short by roughly half. The problem was not money or political will. It was factory floor space. The production lines that had made those shells at Cold War rates had been closed, consolidated, or converted to civilian use across thirty years of peace dividends. Rheinmetall, the largest European ammunition manufacturer, was running three shifts and still could not meet the orders stacking up from a dozen governments simultaneously. The United States faced the same constraint at larger scale. American 155-millimetre production had fallen below three thousand rounds per month in the mid-2010s, a rate that would have been consumed in a single day of heavy fighting on the Eastern Front. The Pentagon set a target of one hundred thousand rounds per month. By mid-2025, after three years of sustained investment and emergency contracting, production had reached roughly forty thousand. The gap between ambition and output was not closing at the speed the war demanded.

When the United States paused weapons shipments in mid-2025, Europe stepped up. European aid increased notably in the months that followed. But total military aid allocations still fell below the average of the preceding three years, because the withdrawal of one major contributor changed the aggregate outcome even as others increased their share. Aid became concentrated among a smaller set of European states and EU institutions. Poland and the Baltic states contributed at rates that dwarfed their GDP share. Germany contributed less than its rhetoric promised. France contributed selectively. The pattern revealed something that the rhetoric of allied unity had obscured: coalition warfare is not a pooling of resources toward a common objective. It is a constantly renegotiated arrangement in which each partner's contribution is shaped by its own domestic constraints, its own electoral calendar, and its own assessment of how much it can afford to give before its own readiness becomes the casualty.

Australia's entire strategic posture rests on the assumption that in a serious crisis, the United States will be willing, able, and available to provide support. The Ukraine experience does not prove that assumption wrong. American support has been substantial by any measure. But it demonstrates something more unsettling than outright failure: that even American support has limits, that those limits are set by domestic politics as much as strategic logic, and that they can tighten abruptly when stockpiles run low or political winds change. Australia cannot plan on the basis of infinite allied capacity. It never could. The difference now is that the evidence is no longer theoretical.

Competing theatres

If Ukraine illustrates the problem of protracted war, the conflict involving the United States and Iran illustrates the problem of competing theatres.

The crisis escalated rapidly from late February 2026. Coordinated American and Israeli strikes against Iranian leadership and infrastructure killed the Supreme Leader and broke the Iranian state. Within days, major shipping lines suspended crossings of the Strait of Hormuz, the chokepoint through which roughly twenty million barrels of oil pass every day, about a fifth of global petroleum consumption. Insurance premiums spiked. Routing changed. By March, the strait had been closed for weeks. In Dublin, one in three petrol stations was dry and police were escorting tanker convoys along motorways. The International Energy Agency declared the disruption worse than 1973 and 1979 combined and announced the largest coordinated emergency stock release in history: four hundred million barrels drawn from government reserves and industry obligations across member states. Four hundred million barrels is not a routine market intervention. It is the international system's fire extinguisher, pulled from the wall because the fire was already burning.

What matters for Australian strategy is the interaction effect. While the Gulf crisis consumed diplomatic bandwidth, military assets, and senior decision-making time in Washington, the war in Ukraine continued. Coercion in the South China Sea continued. The competition for influence in the Pacific Islands continued. The world did not pause one problem while addressing another. It stacked them. And the stacking revealed a truth that peacetime force planning had been designed to avoid confronting: there are not enough Western military assets to cover every commitment simultaneously.

Australia felt this directly. The government deployed an E-7A Wedgetail, one of six irreplaceable airborne early warning aircraft on which the entire RAAF operational concept depends, and provided air-to-air missiles for defensive assistance to Gulf partners. Every enabling system committed to one theatre is a system unavailable for another. Every missile provided to a partner is a missile not in an Australian magazine. Meanwhile, the diplomatic picture beyond the ceasefire talks was bleaker than the public statements suggested. France was holding its forces back. Germany had declined to contribute naval forces. Japan and South Korea, both catastrophically exposed to the Hormuz closure, were keeping their ships close to home. The Royal Navy had made commitments that had not been met. The United States publicly criticised NATO allies for reluctance to help reopen the strait. The allies framed their willingness as contingent on de-escalation. The political will across the democratic world to put warships into the northern Indian Ocean had collapsed into a long series of carefully worded statements about the importance of freedom of navigation. Nobody wanted to help.

That was the context in which Australia discovered something more uncomfortable than the reluctance of its peers. Australia was incapable of helping at scale even if the political will had existed in abundance. When France and Germany declined to commit naval forces, they made political decisions that could have been reversed at any hour by an order from a defence minister to a fleet commander. When Australia did not commit at the scale the crisis demanded, the decision had already been made across thirty years by successive governments that had treated defence as an adjustment at the margin of the budget rather than as the foundation of the country's capacity to exist on its own terms. In Washington, Tokyo, Jakarta, and most importantly Beijing, the lesson was recorded in the ledgers where serious countries keep score. The Western powers that could have intervened had elected not to. The one that could not intervene even if it had wanted to was Australia.

The Western powers that could have intervened had elected not to. The one that could not intervene even if it had wanted to was Australia.

The arithmetic of cheap war

The arithmetic of modern warfare has shifted in ways that punish exactly the kind of force Australia maintains: small, exquisite, and shallow in depth.

A Shahed-type one-way attack drone costs between twenty and fifty thousand dollars. A Patriot interceptor missile costs roughly four million. The ratio is eighty to one at the cheap end and two hundred to one at the expensive end. A defender can maintain high intercept rates and still lose strategically, because every successful interception depletes an inventory that is expensive to replenish and slow to produce. Ukraine's air defences faced this problem from the first winter of the war onward. Russian strikes combined cruise missiles at roughly two million dollars each with Shaheds at fifty thousand each, forcing Ukrainian operators to choose between firing a multi-million-dollar interceptor at a cheap drone or letting the drone through and accepting the damage. The cost-exchange ratio was designed to be unwinnable for the defender using conventional interceptors alone.

Ukraine adapted. Its STING interceptor drone, domestically produced at around two thousand dollars per unit, was developed specifically to avoid burning multi-million-dollar missiles against threats that cost less than a mid-range family car. The innovation was conceptual as much as technical: the recognition that air defence is an industrial problem, not purely a technological one, and that survival depends on matching the adversary's cost curve rather than trying to outspend it at ratios of eighty to one. By 2025, Ukraine was operating some nine thousand drones per day across the front line. First-person-view drones costing a few hundred dollars each were routinely destroying armoured vehicles worth millions. AI-assisted targeting had pushed strike accuracy from 30 to 50 per cent up to approximately 80 per cent. A fifteen-kilometre unmanned zone along the front line was being maintained not by infantry or armoured formations but by cheap, expendable, continuously replenished autonomous weapons.

The lesson for a country in Australia's position is not that drones have replaced conventional military forces. It is that the economics of modern warfare have inverted in ways that favour the side that can produce the most precise weapons at the lowest unit cost and replenish them faster than the adversary can destroy them. Mass matters again, after decades in which Western military planning treated quality as a substitute for quantity. Industrial depth matters again, because a war that consumes munitions at rates that overwhelm peacetime production is a war that the country with the deeper production base wins, regardless of which side has the more sophisticated individual platforms. The United States has been rebuilding 155-millimetre artillery shell production from fewer than three thousand rounds per month in the mid-2010s to a target of one hundred thousand per month, an expansion that has taken years and remains incomplete. Russia's defence industry, which many Western analysts dismissed as hollowed out before the invasion, has ramped to wartime production levels that now exceed the combined output of European NATO members across several ammunition categories.

Modern war rewards mass, endurance, and industrial depth. It punishes forces optimised for peacetime efficiency, forces designed for a world that no longer exists. Australia's defence force is precisely such a force.

The industrial character of modern war extends beyond the ammunition line. Russia's systematic destruction of Ukraine's energy infrastructure demonstrated that targeting the systems a society depends on, power plants, substations, water treatment, heating networks, can degrade a nation's capacity to fight, produce, and endure even when the front lines hold. By the winter of 2024-25, roughly two-thirds of Ukraine's pre-war electricity generation capacity had been destroyed or damaged through successive waves of cruise missile and drone strikes. The KA-SAT cyberattack, launched on the opening day of the invasion, disrupted satellite broadband across Ukraine and into parts of Europe, a component of coordinated operations designed to blind and slow the defender at the point of maximum vulnerability. The lesson is that modern war is fought across every system a society runs on: energy, communications, transport, finance, food distribution. A country that has not hardened these systems, or that depends on exposed infrastructure it cannot defend, is a country that can be brought to its knees without its military ever being defeated in the field.

The denial architecture this series will set out in its later parts is built on these lessons: cheap, precise, distributed, domestically produced weapons in the thousands, not exquisite platforms in the dozens. Hardened infrastructure rather than concentrated vulnerability. Sovereign production rather than foreign dependency. The lessons are available to anyone willing to read them. The question is whether Australia reads them before the examination begins.

Contested sea lanes

Sea lanes are no longer background infrastructure. They are contested space. The disruption to Red Sea shipping that began in late 2023 provided the first major demonstration. Houthi militants, armed with Iranian-supplied anti-ship ballistic missiles, cruise missiles, and one-way attack drones, began targeting commercial vessels transiting the Bab el-Mandeb Strait. By early 2024, container tonnage transiting the Suez Canal had collapsed by eighty-two per cent as commercial shipping rerouted around the Cape of Good Hope, adding ten to fourteen days and roughly half a million dollars in fuel costs per voyage. Twelve per cent of global trade passes through the Suez in normal times. A militia with relatively cheap weapons functionally closed it, and a US-led naval coalition operating under Operation Prosperity Guardian proved unable to reopen it fully, because the cost asymmetry ran against the defenders: every million-dollar interceptor fired at a fifty-thousand-dollar drone was a tactical success and a strategic loss.

The Strait of Hormuz, with its twenty million barrels per day, represents a higher-order version of the same vulnerability. When major shipping lines suspended Hormuz crossings in March 2026, the disruption was not an echo of the Red Sea problem. It was the Red Sea problem multiplied by a factor of ten in economic consequence and applied to the single commodity on which every industrial economy depends. Insurance premiums for Gulf-bound tankers rose to levels that made voyages commercially unviable even before a single ship was struck. The market did the enforcement work that navies could not.

The market did the enforcement work that navies could not.

For an island continent whose economy depends on maritime trade, whose fuel arrives by ship, whose exports travel by ship, and whose allies are separated by oceans, the return of maritime disruption as a strategic reality is foundational. Australia's refined fuel arrives in foreign-flagged tankers operated by companies that make commercial decisions about risk. Those companies do not need to be ordered to avoid a contested strait. They need only to calculate that the insurance premium makes the voyage unprofitable, and the fuel stops flowing. A country that holds fifty days of fuel reserves and depends on imported refined product for eighty per cent of its consumption can be placed under severe economic pressure without a single shot being fired in its direction.

Coercion as routine

Coercion, for Australia, is not a scenario in a classified briefing. It is recent experience. China's trade restrictions, imposed after Canberra called for an independent inquiry into the origins of COVID-19, targeted a wide range of exports through arbitrary border testing, delays, anti-dumping duties, and outright import bans. Coal, barley, wine, beef, lobster, timber, cotton, commodities worth billions of dollars in annual trade were restricted or blocked over the course of 2020 and 2021. The campaign was not comprehensive enough to cripple the economy. It did not need to be. Its purpose was instructive: to demonstrate that economic dependence could be converted into political leverage, and that a country reliant on a single dominant trading partner could be made to feel pain for political disobedience. The lesson was aimed at Australia. It was also aimed at every middle power watching. Dependence was turned into leverage, leverage into punishment, punishment into a lesson. No missiles were required. Sovereignty can be narrowed long before it is formally abolished.

Maritime coercion operates daily across the region with a different instrument but the same logic. Chinese coast guard vessels have used water cannons against Philippine ships near the Second Thomas Shoal, causing damage and injuries in confrontations designed to assert control without crossing into open war. The pattern is deliberate: frequent, ambiguous, physically intimidating, and calibrated to keep escalation control in the hands of the initiator. In November 2023, Australia formally protested an unsafe interaction between a PLA Navy destroyer and an Australian vessel during diving operations. By 2025, Chinese naval activity and live-fire warnings were affecting civil aviation in the Tasman Sea, not in the distant South China Sea, but in waters Australians think of as their own.

None of these episodes, individually, threatens war. Taken together, they constitute a strategic environment in which coercion has been normalised. Pressure is applied routinely, calibrated carefully, and designed to impose costs without provoking the kind of unified response that might check the coercer. This is not the future operating environment. This is the current one.

Is Australia ready?

Is Australia ready for the world described in these pages? The evidence says no. Fuel security remains the starkest indicator: fifty days of stockholding against a ninety-day obligation, with diesel and jet fuel particularly exposed. Defence acquisition runs chronically late, with four hundred and forty-two months of aggregate schedule slippage across major programmes. The force itself is small, sixty-one thousand permanent personnel, sized for peacetime rotation, not for sustained high-consumption operations. And Lowy Institute polling in 2025 found that only fifty-one per cent of Australians support increased defence spending. Half the population has not yet accepted that the world has changed enough to warrant the effort this series argues is necessary.

Australia is not merely underprepared for the world of the 2030s. It is underprepared for the world that already exists. The fiscal programme described later in this series, the defence strategy, the industrial rebuilding, the energy transformation, the demographic renewal, these are not aspirational luxuries. They are responses to conditions that have already arrived. Delay is not neutral. Delay means entering a harder era with fewer options, weaker capacity, and more leverage in the hands of others.

Behind it all stands the one power with the military mass, strategic ambition, economic leverage, and political will to sustain this pattern indefinitely and escalate it at a time of its choosing. The People's Liberation Army is carrying out the largest military expansion since 1945. Its navy is now the largest in the world by hull count. Its missile forces have transformed the balance across the Western Pacific. Its nuclear arsenal is growing at a pace that has no precedent outside the early Cold War. That expansion, its scale, its trajectory, and what it means for Australia, is where this series turns next.
