We see around us that the three traditional domains of national defence — land, sea, and air — have been joined by a fourth.
In the fourth domain the contested ground is the individual citizen's state of mind: their beliefs, why they hold them, and what they are being directed to do about it.
Today's social media and AI-curated algorithms are driving the fragmentation and polarisation of those beliefs. Without shared, verifiable information, a democratic process cannot function.
Democratic values are on the front line — the most vulnerable of which is our fraternité, our sense of common purpose.
Fraternité, unlike the legally defensible values of freedom and equality, cannot be legislated for. It cannot be defended in the courts nor protected by regulation. It exists purely as a (sometimes unconscious) subjective state of mind.
And yet, quiet and hidden, fraternité is the single most important democratic characteristic that binds us with an awareness of both our shared fate and destiny — paradoxically, at the same time.
Fraternité is the lubricant that optimizes the critical functional balance of freedom and equality. Without a sense of fraternité, democratic values become instantly more fragile and attritional.
Fraternité cannot be legislated or campaigned
Europe has spent a decade legislating protection around the fourth domain. It is called the Digital Services Act. Yet, it still has no answer to the actual fight, because the actual fight is not a legal one and fines or bans can only achieve so much. The real battle is psychological, and Europe's essential defense is fraternité.
Fraternité is an internal recognition. It happens inside one person at a time. No directive can make it happen.
It's important to understand what fraternité is not: It is not a Pole coming to love a Spaniard, or a Finn developing warm feelings for a Greek. Nobody is asking for that, and demanding it would be a psychological error. Affection is not a policy lever, and pretending otherwise is how well-meaning EU communications campaigns end up sounding hollow.
Fraternité is something narrower and more durable: the moment a Pole and a Spaniard realise they are facing the same enemy, and reaching for the same future. This is shared exposure, not shared taste, shared aspiration, not shared culture.
A Belfast Catholic and a Belfast Protestant did not need to like each other to recognise, in the years before the Troubles, that they wanted the same vote and the same future for their children.
What undermined that recognition was not a change in how much they liked each other. Instead, third parties found it useful to make each side believe the other was the enemy.
Every national election framed as a referendum on Brussels, rather than on the issue actually on the ballot, does some of that work for free.
Antagonistic framing of Europe as "civilizational suicide" teaches voters, one cycle at a time, to see Europe as something done to them rather than something they are part of.
Fragmentation is not only imported, Europe learns how to practice it at home.
None of this can be fixed by better messaging, for the same reason it cannot be fixed by directive. A campaign that tells citizens they share a fate is asking them to take that claim on faith, and faith is exactly the currency the other side is also bidding for.
What works instead is a condition citizens can step into and recognise the truth of for themselves. The answer is not a better argument for fraternité. It is infrastructure that makes the shared fate real before anyone is asked to believe in it.
Shared infrastructure enables fraternité
Shared infrastructure does two things that a campaign cannot.
First, it creates dependency and habit: once enough of daily life runs through a common system, leaving it gets harder than staying, regardless of how anyone feels about their neighbours that week.
Second, and this is the part usually missed, it creates the condition under which fraternité can be opted into rather than argued for.
Nobody has to be persuaded that they share a fate with the other twenty-six countries running on the same defence network or the same energy grid. They simply notice, the day it matters, that they do. That noticing is fraternité arriving as a result of individual recognition, not as the result of a campaign.
The clearest current case is the digital euro.
For a moment, set aside the technical debate over tokenised deposits and the settlement process, and look at what the project actually does.
Practically, it removes a lever the United States currently holds and has shown willingness to use: European payments today run substantially through Visa, Mastercard and dollar-denominated infrastructure that Washington can, in principle, lean on.
A digital euro, issued and settled in central bank money, cannot be switched off from outside the eurozone. That is sovereignty in the most literal sense. Sovereignty is not a slogan about independence — it's the absence of an off-switch in someone else's hands.
We believe the psychological effect of the digital euro is larger than the practical effect.
Every time a citizen in Naples or Tallinn pays with the digital euro, they are not thinking about monetary sovereignty. They are buying coffee. But the system underneath that purchase is the same system, running the same way, for every other citizen in the eurozone, regardless of who holds power in any one capital that month.
That is fraternité built from below, transaction by transaction, rather than asserted from above.
Fraternité from habit
This is the model worth generalising. Not a single flagship project, but a habit: wherever Europe can choose between building an argument and building a habit that produces the same recognition as a side effect, choose the habit.
The digital euro is the clearest current example because the choice is live and the stakes are visible. It will not be the last place this logic applies.
Fraternité is never going to come from a treaty. It comes from twenty-seven countries discovering, transaction by transaction, system by system, that they have already been depending on each other the whole time.
That the discovery, once made, does not need anyone's permission.
