It has become the most expensive arms race in human history. Yet the true cost may not be measured in dollars, but in the survival of economies already on the brink. In 2024, governments collectively funneled $2.7 trillion into their militaries—a record-breaking figure—despite being weighed down by pandemic debt, battered by inflation, and watching their infrastructure rot. Today we examine "why the world is preparing for wars it cannot afford to fight?"
For decades, the Scranton-based General Dynamics Ordnance and Tactical Systems factory ran just one or two shifts, producing 10,000–14,000 artillery shells a month—enough to keep U.S. reserves healthy and allies supplied. That era is gone. Today, the factory roars like it’s 1944 again. Sparks fly as welders finish steel casings, while 2,000-pound bars of metal are pressed into shape by hydraulic giants. Every four minutes, another 155mm shell rolls off the line. The plant now works nonstop—three shifts, seven days a week—pumping out nearly 40,000 shells monthly. Even so, demand dwarfs supply. Ukraine burns through more artillery in two weeks than America made in an entire year before 2022. Each new shell replaces what was sent abroad, but the math is unforgiving: every round costs the equivalent of a small fortune to the average U.S. family.
This is modern war—an equation where economics and firepower collide.
Global spending now mirrors, even surpasses, Cold War levels. The U.S. alone committed $886 billion to defense in 2024, a sum greater than most nations’ entire economies. Within that budget, the Pentagon’s base spending is enormous, but emergency add-ons are staggering: $30.6 billion for ammunition stockpiles—more than many countries’ whole militaries—and $113 billion in foreign aid, much of it to replace U.S. arms already shipped overseas. Washington is effectively bankrolling three separate conflicts at once: Ukraine versus Russia, escalating Middle Eastern hostilities, and a high-tech arms race with China.
At the same time, interest payments on America’s $33 trillion debt have ballooned to $640 billion a year, nearly equal to defense spending itself. Treasury officials call this “uncharted fiscal territory,” where the cost of borrowing begins competing with national defense for survival.
China’s trajectory is no less alarming. Beijing officially reported a $296 billion defense budget for 2025, a steady 7% annual rise for over a decade. Western analysts, however, estimate the real figure could top $450 billion once covert programs and dual-use technologies are included. China now commands the world’s largest navy by ship count, has doubled its nuclear arsenal since 2020, and deploys hypersonic weapons that U.S. systems cannot reliably stop. Every Chinese breakthrough forces Washington into billion-dollar countermeasures, fueling what experts call “the most expensive chess match in history.”
Europe, too, has awakened. Once reluctant, Germany pledged €100 billion for defense—the largest in its history—while doubling long-term spending targets beyond NATO’s 2% requirement. Poland sprinted ahead, devoting 4% of GDP and buying tanks by the thousand. Even neutral Sweden joined NATO, reintroduced conscription, and mailed survival pamphlets to every household. Switzerland quietly approved billions for fighter jets and updated Cold War bunkers. Japan, long pacifist, approved its largest defense budget since WWII while carrying the highest debt burden in the developed world.
The pandemic turbocharged all of this. Governments that borrowed trillions to keep their economies alive are now borrowing trillions more to rearm. Europe, crushed by energy crises after Russia’s invasion of Ukraine, is still cutting checks for new tanks, jets, and missile systems. Italy, once laughing at NATO’s demands, now talks about hitting 4% of GDP on defense by rebranding megaprojects as “national security.” Britain locked itself into a half-century submarine pact with Australia. Even tiny Baltic states are spending more on defense than on healthcare or education combined.
The numbers are staggering, and the weapons breathtakingly expensive. Each U.S. hypersonic missile costs over $14 million. A B-21 stealth bomber comes in at $2 billion per plane. The F-35 program is projected at $1.58 trillion over its lifetime—software updates included. Ukraine burns through $50,000 in ammunition every single minute. In this economy of war, even drones and cyber defenses run into the billions.
Yet the deeper problem is supply itself. Production bottlenecks, rare earth mineral shortages, and semiconductor dependency make it impossible to simply “spend our way” to safety. China dominates rare earths, Taiwan produces half the world’s semiconductors, and a war there could unleash a $10 trillion economic shock overnight.
History warns us where this leads. The Soviet Union bankrupted itself in Afghanistan. Britain won WWII but emerged broke. The U.S. spent $12 billion a month at the height of Iraq and Afghanistan, and Taiwan scenarios predict costs of $1 trillion per year.
This is the classic “security dilemma”: one nation rearms for defense, another interprets it as offense, and the spiral accelerates. Carriers breed submarines, missiles breed missile shields, and neutrality vanishes. What we see now is the costliest game of chicken the world has ever played—one where the prize may be nothing but mutual ruin.
So the ultimate question lingers: are these nations preparing for victory, or for destruction? In their desperate attempt to prevent annihilation, have they already set it in motion?
