The Citadel of Democracy

On freedom, resilience, and measured steadfastness

Europe is once again preparing itself for a world in which war is no longer unthinkable.

Since the Russian invasion of Ukraine, the conversation has turned to rearmament, larger armies, air defence, drones, ammunition stockpiles, and the possibility that European armed forces may one day be called upon to repel a Russian attack. Governments are raising their defence budgets and bracing themselves against the visible threat from without.

That is necessary. A democracy that cannot defend itself militarily makes its freedom contingent upon the willingness of others to defend it on its behalf.

But a citadel can fall in more than one way.

It can be assaulted head-on by armies, missiles, and drones. It can also be weakened by cyberattacks, sabotage, disinformation, foreign interference, social polarisation, religious and political extremism, and the gradual erosion of public trust in its institutions.

At times these threats reinforce one another. Foreign powers need not themselves manufacture every division within Europe. It may be sufficient to amplify existing conflicts, to render radical voices more visible, and to persuade citizens that their government, their courts, and their democracy can no longer be trusted.

Military defence alone, therefore, is not enough.

The Inner Citadel

Marcus Aurelius described the human mind as an inner citadel: a place where reasoned judgement holds firm when fear, anger, temptation, and deception assail it from every side.

For Marcus, that citadel was no refuge in which to hide from the world. He was not merely a philosopher but an emperor. Even as he guarded his inner fortress against fear, hatred, and despair, he bore responsibility for the protection of others and for the frontiers of the empire.

The Democratic Citadel

Let us now conceive of the democratic constitutional order as such a citadel.

Its walls are composed of freedom, human dignity, equality before the law, and an independent judiciary. Its gates are our democratic procedures. Its sentinels are the police, the courts, the armed forces, the civil service, the intelligence services, a free press, and ultimately every citizen who refuses to surrender independent judgement.

Beyond the walls stand potential military adversaries. Around the walls operate foreign intelligence services, cyber actors, and propaganda networks. Within the walls there are political, religious, and ideological movements that respect our freedoms — but also groups that may exploit our openness to strip those same freedoms, gradually, from others.

The Gates Are Being Tested

The danger arises when the citadel is tested at all these points simultaneously.

At one wall, military readiness is put to the proof. Elsewhere, digital systems are attacked, energy supplies disrupted, and social divisions inflamed. At another gate, foreign financial flows are concealed. Elsewhere still, laws are pressed to their outermost limits, administrators are intimidated, and democratic freedoms are exploited to build antidemocratic influence.

At the same time, the sentinels grow overburdened by an ever-increasing volume of incidents, investigations, and legal proceedings.

No single attack appears, in isolation, large enough to bring the citadel down. Therein lies precisely the danger.

Just as the velociraptors in Jurassic Park continuously test the fence, probing for wherever attention lapses, wherever capacity is lacking, and wherever rules exist but are not consistently enforced.

Every breach yields information. Every violation that goes without consequence reveals where the current has gone from the fence. Every weakness left unrepaired becomes the point of departure for the next incursion.

Many Hands, the Same Walls

Those who would weaken the citadel need not act from a single command centre. A foreign power, an extremist organisation, a criminal network, and an opportunistic politician may each pursue entirely different objectives and yet collectively undermine the same walls.

Some are driven by geopolitical ambition. Others by an absolute religious or political conviction. Others still by financial gain, social influence, or electoral advantage. All may profit from fear, division, administrative inertia, and selective moral outrage.

How Would Marcus Respond?

Not with panic or hatred. Not by declaring entire population groups to be the enemy. To do so would be to corrode the citadel from within through the very injustice of its own defenders.

But neither would he persist in endless deliberation once it had become sufficiently clear what was taking place. He would purify his perception, separate fact from interpretation, establish the true nature of the danger, and then act.

He would send the sentinels to the vulnerable points, repair the damaged walls, and close the gates that had been abused. He would prevent those who receive the citadel's protection from using that same protection to dismantle its foundations.

Not out of vengeance, but out of responsibility.

In doing so, the defenders of the citadel must not become fanatics. Fanaticism closes off reasoned judgement and transforms every difference into enmity. But the opposite of fanaticism is not passivity. It is measured steadfastness.

Europe must therefore possess sufficient military strength to deter attack from without. It must protect its digital and vital infrastructure against hybrid threats. And it must simultaneously defend the rule of law against extremism, subversion, and the abuse of democratic freedoms.

The Four Virtues

All four virtues are required for this task.

Wisdom recognises the true threat and prevents fear, propaganda, or political interest from being mistaken for fact.

Justice determines what must be protected, applies the same law to everyone, and refuses to hold innocent people accountable for the actions of others.

Courage sets justice in motion. It ensures that necessary boundaries are genuinely upheld even under military, social, legal, and political pressure.

Temperance prevents defence from degenerating into vengeance, arbitrariness, collective suspicion, or repression.

Steadfastness arises where justice and courage meet. It means that the same boundary holds today, tomorrow, and under mounting pressure. That laws do not vary according to the identity of the transgressor. That demonstrated threats are not merely recorded but met with a proportionate response.

To go to the utmost does not mean that anything becomes permissible in the course of defence. It means that we remain, to the utmost, faithful to what makes the citadel worth defending. If, in order to save it, we ourselves abandon justice, humanity, and freedom, we may have preserved the walls — but we will have lost the citadel.

The Decisive Question

Our democracy need not disappear in a single great war.

It can be threatened from without and simultaneously hollowed out from within. By military intimidation, sabotage, and propaganda, but also by thousands of small transgressions that we investigate, record, and eventually begin to regard as normal.

The decisive question, therefore, is not only whether Europe can withstand a Russian attack by military means.

The question is also whether we possess the wisdom to recognise all forms of pressure in good time, the justice to protect every citizen equally, the courage to genuinely repair demonstrated weaknesses, and the temperance to remain humane and democratic throughout the course of our defence.

Neither fanatical, nor naïve, nor passive — but clear-sighted, just, and steadfast. As resolute as the adversaries of the free society, yet never their equal in method.

The democratic constitutional order is our shared citadel.

Defend it against the armies beyond the walls, against the subversion within the gates, and against the fear and hatred that may destroy it from within ourselves.
