Defense Capability and War Readiness

I. Two Words

In German security policy discourse, two terms circulate that are often used synonymously but mean different things: Verteidigungsfähigkeit (defense capability) and Kriegstüchtigkeit (war readiness).

The first word is pleasant. It sounds like a fence, like protection, like the right to defend oneself. It fits a pacifist mood. One is only defending oneself, after all. One doesn't want to harm anyone. One is merely reacting.

The second word is unpleasant. It contains the word "war." It sounds like attack, like aggression, like something Germany never wanted to be again. It doesn't fit into Sunday speeches. It frightens.

The difference between the two words is the difference between wish and reality.

II. What Defense Capability Means

Defense capability, as the term is usually used, means the ability to repel an attack. It is a reactive concept. The enemy attacks, we fend them off. The enemy comes, we stop them. The enemy shoots, we shoot back.

The concept assumes:

• The attack is limited — in time, space, intensity
• The defense succeeds quickly — before reserves are exhausted
• The enemy gives up — when they realize they're not getting through
• There is an after — an end to the conflict to which one returns

Defense capability is the concept of the police officer, not the soldier. The police officer fends off an attack and then returns to normality. The conflict lasts minutes, perhaps hours. Then it's over.

The concept works — against burglars, rioters, limited threats. It does not work against an enemy who does not give up.

III. What War Readiness Means

War readiness is something different. It is the ability to wage war. Not to win the war in a quick battle, but to endure the war. Weeks. Months. Years.

War readiness encompasses:

Material. Not just the weapons you have, but the weapons you can reproduce. Not just the ammunition in storage, but the factories that resupply. Not just the tanks at the front, but the spare parts that keep them running.

People. Not just the soldiers under contract, but the reservists who can be called up. Not just the trained, but those who can be trained. Not just those fighting today, but those who will fight tomorrow when the first have fallen.

Economy. The ability to convert an economy to war footing. Factories that build tanks instead of cars. Logistics that transport ammunition instead of consumer goods. Workers who produce armaments instead of services.

Society. The willingness of the population to make sacrifices. To accept rationing. To send sons and daughters to war. To endure fear. To bear losses. To continue when it hurts.

Leadership. A political class that makes difficult decisions and stands by them. That implements unpopular measures. That communicates honestly. That doesn't collapse when the first setbacks come.

War readiness is not just a military capability. It is a comprehensive societal condition.

IV. The Comparison

The question is not which concept is "better." The question is which concept matches the threat.

Against a limited attack, defense capability suffices. Against an enemy willing to wage a long war, it does not.

V. The Lesson of Ukraine

On February 24, 2022, Russia attacked Ukraine. Most observers expected a quick Russian victory. Kyiv would fall in days. The Ukrainian government would flee or capitulate. The war would be over in weeks.

It turned out differently. Ukraine was defense-capable — it repelled the initial attack. But it was also war-ready — it endured.

Almost four years later, the war continues. It has become a war of attrition. Artillery duels. Trench warfare. Daily losses on both sides. No quick victory, no quick end.

What did Ukraine need?

Material. Not just the weapons it had on day one, but constant resupply from the West. Ammunition consumed at hundreds of thousands of rounds per month. Spare parts, repairs, new systems.

People. Not just the professional army, but mobilization. Reservists, volunteers, conscripts. A society that sends its men to the front — and its women to the factories.

Will to endure. A population that endures bombardments, survives power outages, loses loved ones — and doesn't give up. A leadership that stays, fights, holds together.

Ukraine was not prepared for this war. No one was. But it proved itself war-ready — improvising, learning, enduring.

The question is: Would Germany be capable of this?

VI. The German Situation

Since the "Zeitenwende" (turning point), Germany has talked a lot about defense. One hundred billion special fund. Two percent of GDP for defense. New weapon systems. More personnel.

That is defense capability. It is the attempt to be able to repel the first wave. It is important and right.

But is Germany war-ready?

Material. The Bundeswehr has ammunition for a few weeks of intense combat. German defense industry produces at peacetime levels. Converting to war production would take months, perhaps years. Supply chains are global and vulnerable.

People. Conscription was suspended in 2011. There are hardly any trained reservists. The Bundeswehr struggles for every recruit. A mobilization Ukrainian-style would be legally, practically, and socially almost impossible.

Economy. The German economy is optimized for export, not autarky. It depends on energy imports, raw material imports, components from around the world. A long war would present challenges not contemplated since 1945.

Society. German society is not geared for war. Willingness to sacrifice is not a cultivated virtue. The thought that sons and daughters could fall is foreign. The expectation is security, not sacrifice.

Leadership. The political class avoids the word "war." It speaks of "defense," of "deterrence," of "security." It avoids the uncomfortable questions: What if deterrence fails? What if war comes? What if it lasts long?

Germany is becoming more defense-capable. It is not war-ready.

VII. The Uncomfortable Thought

Here is the thought no one wants to speak:

Defense capability without war readiness is an illusion.

It works only if the enemy plays along. If they give up after the first setback. If they are not willing to wage a long war. If they accept the same rules as we do.

But what if they don't give up? What if they are willing to fight for years? What if they accept more losses than we do? What if they know our weakness — and count on it?

Then defense capability very quickly becomes capitulation capability. The ability to defend yourself until the ammunition runs out. The ability to hold out until society collapses. The ability to fight until you can't anymore — and then surrender.

That is not defense. That is delayed losing.

VIII. The Choice

Germany has a choice. It can pretend that defense capability is enough. It can hope the emergency never comes. It can bet that deterrence holds and war remains an abstraction.

That is a legitimate choice. Perhaps it works. Perhaps war never comes. Perhaps deterrence holds. Perhaps NATO is enough. Perhaps America protects. Perhaps one gets lucky.

Or Germany can be honest. Admit that defense capability is not enough if the enemy doesn't play along. Ask the uncomfortable question: What would we need to do to be war-ready?

The answer would be unpleasant. It would mean:

• Massively expand arms production — with reserve capacity for emergencies
• Reintroduce conscription — or at least discuss it
• Build up reservists — hundreds of thousands, not tens of thousands
• Hold a societal debate — about sacrifice, about duty, about what we are willing to defend
• Make the economy more resilient — less dependent, less vulnerable
• Leadership that speaks plainly — even when it's unpopular

No one wants to hear that. No one wants to pay for that. No one wants to do that.

So they speak of defense capability.

IX. Epilogue

This text is not a plea for war. It is a plea for honesty.

If we want peace, we must understand what war means. If we want deterrence, we must understand what deterrence requires. If we want to defend ourselves, we must understand what defense really means.

The distinction between defense capability and war readiness is not semantic quibbling. It is the difference between wishful thinking and realism. Between what we would like and what we need.

Germany can decide to be defense-capable and hope for the best. That is a choice.

But it should know what it is choosing. And what it is risking.

For the enemy, if they come, will not ask which word we prefer.
