If you want to live in peace, you have to be willing to defend it.
Eight decades after vowing never again to let its military ambitions threaten the world, Germany finds itself compelled by history's return to rebuild the very institutions it once dismantled in penance. Russia's invasion of Ukraine in 2022 broke the long postwar spell, and Berlin has since committed to an 80 percent surge in defense spending, a permanent combat brigade in Lithuania, and a Bundeswehr reshaped for a continent that can no longer assume American protection. The transformation is not merely strategic but existential — a nation wrestling with the weight of its past while accepting that the future may demand it bear arms again.
- Russia's invasion of Ukraine shattered Germany's decades-long posture of military restraint almost overnight, forcing a reckoning that politicians had deferred since 1945.
- Defense Minister Pistorius warns that Russia could be positioned to threaten NATO's eastern flank by the end of the decade, leaving Germany with a closing window to rebuild credible deterrence.
- Enlistments have risen 23 percent, yet polls show most young Germans aged 15 to 25 refuse to volunteer — a recruitment gap so severe that conscription, still a raw subject, is back on the table.
- Germany is betting on asymmetric innovation — surveillance drones already battle-tested in Ukraine, biotech startups steering cockroaches on reconnaissance missions — to offset Russia's sheer production advantage in conventional arms.
- Rheinmetall, once a symbol of German industrial militarism, is expanding across 13 European factories while its CEO survives alleged Russian assassination plots, signaling how high the stakes have become.
- Germany's first permanent combat brigade abroad since World War II now stands in Lithuania — a country once occupied by Nazi forces — marking a symbolic and strategic turning point the entire alliance is watching.
At a training base in northwest Germany last November, fresh recruits moved through drills designed for a scenario their instructors hoped would remain hypothetical. The major overseeing the exercises noted something different about this generation: they understood, in a way earlier cohorts had not, that the skills being hammered into them might one day be used in earnest. The war in Ukraine had made that real.
For decades, Germany had treated military restraint as a moral obligation — a reckoning with its catastrophic past. Defense budgets shrank, equipment deteriorated, and soldiers sometimes purchased their own gear. Then, three days after Russia's February 2022 invasion, Chancellor Olaf Scholz stood before the Bundestag and named the moment: a zeitenwende, a turning point. He announced a 100 billion euro fund to rebuild the Bundeswehr. His successor Friedrich Merz went further, exempting defense spending from Germany's constitutional debt brake. The budget is now on track to rise nearly 80 percent by 2029.
Defense Minister Boris Pistorius, who remembers the Cold War and the illusion of permanent European peace it eventually produced, has become the public face of the transformation. He speaks plainly about Vladimir Putin's ambitions — not just Ukraine, but a restored sphere of dominance and a seat among global superpowers. Germany, he insists, must be combat-ready by 2029. Enlistments have climbed 23 percent, and the Bundeswehr aims to add 75,000 troops by 2035. But recruitment remains difficult. An overwhelming majority of young Germans say they would not volunteer, and the government may yet reintroduce conscription — a prospect that still draws protesters into the streets.
The rearmament is also reshaping what German defense looks like. Berlin-based Quantum Systems secured a contract to supply the Bundeswehr with nearly 750 surveillance drones — technology already proven on Ukrainian battlefields, where thermal-equipped drones helped halt a Russian river crossing through smoke and chaos. Meanwhile, a startup called SWARM Biotactics is developing electrode-fitted cockroaches for reconnaissance, a reminder that Germany cannot match Russia's conventional production capacity and must instead compete through intelligence and innovation.
At the industrial scale, Rheinmetall — a name stretching back to both World Wars — has reinvented itself as a diversified defense giant, building or expanding 13 factories across Europe. Its CEO has reportedly survived an assassination plot linked to Russian intelligence. The company's acceleration reflects a broader European recognition: the assumption that Washington would always answer the call can no longer be taken for granted.
In 2024, Germany stationed its 45th armored brigade — 5,000 troops — permanently in Lithuania, a country that suffered Nazi occupation and now welcomes German soldiers as a shield against Russian pressure. It is the first permanent German combat deployment abroad since 1945. When new recruits were sworn in publicly in Berlin, they shouted 'Deutschland' into the air — a sound not heard in that context for eighty years. The meaning, Pistorius has argued, is entirely different now: not conquest, but the defense of an order that freedom requires the willingness to protect.
In November, German military instructors put a squad of fresh recruits through punishing drills at the Munster Army Base in northwest Germany. The exercises were designed to prepare them for something the soldiers hoped would never come: defending their position against an enemy assault. When asked if he'd noticed a difference in recruits compared to years past, the major overseeing the training didn't hesitate. The young soldiers arriving now understood the stakes in a way their predecessors hadn't. They grasped that the skills being drilled into them—the movements, the tactics, the discipline—might one day be needed for real. The war in Ukraine had changed that calculus entirely.
For decades after World War II, Germany had embraced military restraint. The country's brutal history weighed heavily on its conscience, and defense spending had atrophied to the point where soldiers were sometimes forced to buy their own equipment. But Russia's 2022 invasion of Ukraine shattered that long peace, and the landscape shifted almost overnight. Three days after the invasion began, then-Chancellor Olaf Scholz stood before the Bundestag and declared the moment a zeitenwende—a turning point. He announced a special 100 billion euro fund to begin rebuilding Germany's military. By the time Friedrich Merz took office as chancellor in 2025, the rearmament was accelerating. Merz, concerned about both Russian aggression and American threats to withdraw NATO support, pushed parliament to exempt defense spending from Germany's constitutional debt brake. The money began flowing in earnest. The defense budget is now projected to rise nearly 80 percent by 2029.
Defense Minister Boris Pistorius, a Social Democrat kept in his post by the conservative Merz, has become the public face of this transformation. Pistorius grew up during the Cold War and remembers a time when Europeans believed such conflicts belonged to history. Since February 2022, he has said, that illusion has evaporated. He speaks bluntly about Vladimir Putin's ambitions—not merely to conquer Ukraine, but to restore a Soviet-style sphere of dominance and position Russia as one of three global superpowers alongside China and the United States. Pistorius has warned that Russia is rapidly rebuilding its military and could be positioned to threaten the West by decade's end. Germany, he believes, must be ready to defend itself by 2029. Enlistments have surged 23 percent, and the Bundeswehr aims to add roughly 75,000 active duty troops by 2035. Yet recruitment remains a challenge. A recent poll found that an overwhelming majority of Germans aged 15 to 25 would not volunteer to serve, a reluctance rooted in the country's historical trauma. If volunteer numbers fall short, the government may reintroduce conscription—a prospect that still sparks public protest.
Germany's rearmament is reshaping its defense industry. Quantum Systems, a Berlin-based drone manufacturer, landed a 25 million euro contract with the Bundeswehr to produce up to 750 intelligence, surveillance, and reconnaissance drones. The company already has more than 1,500 drones in daily use across Ukrainian battlefields. During the early months of the invasion, when Russian forces attempted to cross the Donets River in eastern Ukraine, a Quantum drone equipped with thermal imaging helped Ukrainian forces see through smoke and explosions to target and halt the advance. That success demonstrated the technology's potential and opened doors for the company across Europe.
The innovation extends to the unconventional. The Bundeswehr is funding a startup called SWARM Biotactics to develop technology that can steer Madagascar hissing cockroaches autonomously and deploy them on reconnaissance missions. Scientists attach electrodes to the insects' antennae—they insist the procedure causes no harm—stimulating their natural navigational abilities. The electrodes are housed in tiny backpacks alongside batteries and microchips. The goal is to eventually shrink the technology further and equip the roaches with cameras, microphones, and radar to infiltrate war zones. The logic is pragmatic: Germany cannot match Russia's raw production capacity in tanks and conventional weapons, so it must compete through intelligence, autonomy, and innovation.
Rheinmetall, Germany's largest defense contractor and a major arms supplier in both World Wars, has become the centerpiece of the rearmament effort. CEO Armin Papperger has transformed the company from primarily an ammunition manufacturer into a diversified defense giant spanning vehicle platforms, digitization, satellite technology, and naval systems. Rheinmetall is building and expanding 13 arms factories across Europe. Papperger has become a target—Russian intelligence allegedly plotted his assassination—but the company has only accelerated. He acknowledges that the old security architecture has collapsed. For two generations, Europeans believed that if trouble arose, Washington would respond. President Trump made clear that assumption no longer holds. Europe must defend itself.
In 2024, Germany deployed its 45th armored brigade—5,000 troops—to Lithuania for a permanent stationing. Lithuania, brutally occupied by Nazi Germany during World War II, now welcomes German soldiers as a bulwark against Russian pressure on NATO's eastern flank. It marks Germany's first permanent combat-ready brigade deployment abroad since the war ended. The symbolism is profound and deliberate. When new recruits were sworn in publicly in Berlin, they shouted "Deutschland" into the air. The world has not heard Germany assert itself militarily in this way since 1945. Yet the context is entirely different. This is not aggression but deterrence, not conquest but defense of the international order itself. As Pistorius told interviewer Bill Whitaker, defending freedom requires willingness to fight for it. Without that resolve, leaders like Putin will simply take it away.
Notable Quotes
Since February 2022, we all experience in Germany and in Europe that the war is back. We never expected that. And we were so hopeful that it would never happen again. But it does.— Defense Minister Boris Pistorius
We have to be smarter. We have to use intelligence. We have to use autonomy—because we wouldn't have enough personnel or enough equipment if you look at what Russia produces right now.— Stefan Wilhelm, SWARM Biotactics
The Hearth Conversation Another angle on the story
Why does Germany's rearmament matter now, when it's been so reluctant for so long?
Because the old security guarantee—that America would always be there—has evaporated. Trump made that explicit. Germany realized it had to become capable of defending itself, not just hoping someone else would.
But doesn't Germany's history make this complicated?
Enormously. The Holocaust memorial stands near the parliament building where they're voting to rebuild the military. That weight doesn't disappear. But the war in Ukraine made the choice feel unavoidable—pacifism looked like a luxury they could no longer afford.
The recruitment numbers are troubling, though. Most young Germans don't want to serve.
That's the real tension. They're trying to add 75,000 troops by 2035, but a poll shows an overwhelming majority of 15 to 25-year-olds would refuse. If volunteers don't materialize, they'll have to bring back the draft—which will reopen old wounds.
What about the technology angle? Drones and robot cockroaches seem almost absurd.
It's actually strategic desperation. Germany can't outproduce Russia in tanks and ammunition. So they're betting on being smarter—using autonomy and intelligence to compensate for what they lack in raw numbers.
And Rheinmetall is the big winner here?
Absolutely. They've gone from being primarily an ammunition company to a diversified defense giant. They're building factories across Europe. The CEO was even targeted for assassination by Russian intelligence, but it didn't slow them down.
What's the timeline that matters?
2029. That's when Pistorius says Germany needs to be combat-ready. It's also when he believes Russia could be positioned to threaten the West. Everything is being built toward that deadline.
