Just War and Just Peace

As the Ukraine War passes another milestone, can any war be considered just? Christine Schliesser explores Just War theory and a possible path to Just Peace.

Will Germany deliver Leopard 2 tanks to Ukraine? No? Yes? When? Media discussion of the war that the Russian Federation started against Ukraine in 2014 and that entered a new stage one year ago, currently centres on questions of weaponry. Who else will send tanks? And what about fighter aircrafts? No? Yes? When?

In classical military ethics, which has long been dominated by the so called Just War Theory, these questions fall under ius in bello, the right conduct in war. This also includes discussions on proportionality, military necessity and the differentiation between combatants and non-combatants.

Just War Theory has a long tradition in Christian thought. Church Father Ambrose argued that whoever does not ward off injustice from his fellow man (or woman for that matter) when he can, is as guilty as he who commits it. Ambrose’s student, Augustine, then developed this thought in more detail as he laid the foundations for what could be called a bellum iustum, a just war.

Even before going to war, the criteria of the ius ad bellum, the right to go to war, must be satisfied. These include, for instance, a just cause, legitimate authority, prospect of success, right intention and last resort. We encounter these criteria again in slightly modified form in our modern international law. In view of these guidelines, of Russia’s breach of international law, and of Ukraine’s right to self-defence, the on-going war in Ukraine clearly seems to be a just war. Or is it?

Nothing holy or just

Two points need to be made in this discussion. Firstly, there are no just or holy wars. Period. Or as 150 churches, after the horrors of the Second World War, put it in Amsterdam in 1948: ‘War is contrary to the will of God.’ Wars are always an evil and an expression of the failure of human beings to strive for peace. This also holds true for the war in Ukraine. And this means that we need a new dimension in the debate, namely guilt.

Every action – and inaction – here involves guilt. As the German pastor Dietrich Bonhoeffer, who was killed by the Nazis for his engagement in a plot against Hitler, put it:

‘everyone who acts responsibly becomes guilty’.

And even if we become guilty for the sake of the other person, our guilt remains just the same. Yet, as Bonhoeffer concludes, we trust in the grace of God, who calls us to responsible action. , Bonhoeffer’s ideas have been considered dangerous and easily misused to justify any crime, as forgiveness is always available. Nevertheless, we must acknowledge the reality of guilt that pervades any war, including the war in Ukraine.

Just Peace

Secondly, recent years have seen a new kid on the block: Just Peace Theory. While Just War Theory looks at a conflict from the perspective of violence, Just Peace Theory puts the focus on peace. This includes adding a third set of criteria. Ius post bellum looks at justice after a war. We know that after a conflict is before a conflict. We therefore need to pay more attention to what happens after the weapons finally fall silent.

Here, the experiences of truth and reconciliation processes worldwide can help. Both dimensions belong inseparably together and both already begin during a conflict, not just after it. Truth, for example, requires the documentation of war crimes committed by all parties to ensure the prosecution of war criminals later on. And reconciliation is the conditio sine qua non for sustainable peace.

Russia’s war against Ukraine and its threats against NATO and Western countries demonstrate, not least that after the end of the Cold War, opportunities for genuine and sustainable reconciliation were missed as latent hatred, prejudices and stereotypes were allowed to linger.

Just Peace Theory emphasizes that building peace is an art and a craft. It requires specific skills, training and preparation. It also requires virtues of grace, persistence and forgiveness, Countless documented examples world-wide supply empirical proof that these methods actually work. Perhaps it is worth devoting some of the $2,113 billion (2021) of global annual military expenditure for training non-military approaches to address conflict resolution? To learn how to build peace as much as how to wage war? No? Yes? When?

Pathways to Peace

One such initiative is Pathways to Peace. Aiming at peace, justice and reconciliation in times of war, this initiative is currently being developed through the Conference of European Churches, a group of some 120 member churches in 38 countries. With their long-term involvement and intimate knowledge at the grassroot level, faith actors in civil society seem uniquely positioned to connect people, heal relationships, offer a new social imaginary and facilitate practical help.

The objectives of Pathways to Peace include among others to facilitate safe spaces for honest exchange between Ukrainian and Russian church leaders, to develop a network of church leaders and other civil society leaders for exchange on the preparation of peace or to bring together European youth, in particular Ukrainian and Russian young refugees.

The immense potential of faith actors in transforming conflict and building sustainable peace seems to have gone largely unnoticed in the public sphere. Given the prominence of faith in this conflict, it is about time that all relevant actors in our societies, including faith-based initiatives, joined forces to counter this major crisis of our time.

Keep calm and don’t cry? Why Remembrance Day needs emotion

We gather to grieve—but only in ways that won’t make others uncomfortable

In the coming days across Britain, the poppied public will gather around cenotaphs. Polished boots, flapping scarves, bowed heads, fidgety Brownie-Guides, regimented Cadets – all will pause in hushed reverence as the Last Post echoes in the cold air. It’s a scene that’s meant to unite us, a national ritual of grief and gratitude.

But for one close friend of mine, it is a ritual that is almost unbearable. She doesn’t go to local remembrance events anymore. Not because she doesn’t care, but because she cares so deeply that she weeps. Real tears - big ugly ones. And while the music is designed to evoke poignancy, and the silence is meant to be solemn, she fears that her public displays of emotion are perceived by those around her as a bit over the top. Surely the British stiff upper lip ought not to tremble, let alone cry? We are the nation of Keep Calm and Carry On after all. So, she stays away.

Philosopher Sara Ahmed, in her book The Cultural Politics of Emotion, offers some profound insights into why we act the way we do about our feelings. Ahmed writes that emotions are often cast as a kind of weakness – a betrayal of our ability to reason. They are something messy and animalistic, something we are meant to control. In this view, to show emotion is to reveal that you have been shaped by something or someone outside yourself. It reveals that you are vulnerable, only human after all.

And yet – isn’t that exactly what Remembrance is about? When we gather at a cenotaph, we are not there to demonstrate the stiffness of our upper lips. We are there to grieve; we are there to be moved by the stories of young lives cut short, families broken, sacrifices made. The very design of the ceremony – the bugles, the silence, the laying of wreaths – is intended to stir emotion. Yet, paradoxically, there is a hidden social code of conduct that seems to say: but not too much.

Ahmed explores several ways in which the social world shapes our emotional lives. Emotions, she argues, are not just private feelings bubbling up from within, they are also social, and they can be contagious. The atmosphere of a Remembrance service is just that – carefully crafted to invoke communal feeling: solemnity, pride, sadness, reverence. The power of such rituals lies in the way they gather us into a collective “we.” But that same collective can turn cold when someone expresses too much, breaks the silent script, or cries too loudly.

In one of his letters to the first Christians, the apostle Paul wrote: “Rejoice with those who rejoice, weep with those who weep.” It’s a call not just to feel one’s own emotions, but to enter into the emotions of others, to share in them and show solidarity. And this, in essence, is what the cenotaph service is all about. It is a physical and symbolic place to “weep with those who weep” – to acknowledge that loss and grief are not individual experiences, but shared ones. A soldier’s death, whether in historic conflict or in the present day, is not just a family’s burden. A death on behalf of all of us belongs to all of us.

So why do people seem uncomfortable when someone like my friend weeps openly in this space? Perhaps it is the long shadow of British wartime stoicism. At one time, the slogan “Keep calm and carry on” was intended to protect a struggling populace from giving in to despair, it was intended to create a shared emotion of resilience. But perhaps an unfortunate side effect is that it has perpetuated a notion that dignity lies in restraint. This is a cultural script, and it isn’t universal. In many parts of the world, public mourning is expected, even encouraged. Wailing, keening, clutching each other in grief – some cultures see these as honourable ways of expressing sorrow. They honour the dead by fully feeling their absence.

We need to ask ourselves: what is lost when we suppress this kind of mourning?

When we limit how people are allowed to feel – or, at least, how they are allowed to express their feelings – do we risk losing the very power of the ritual? Do we risk turning the cenotaph into a site of performance rather than connection, excluding those who feel too deeply to fit inside a narrow band of “acceptable” solemnity?

This is not a call to abolish the dignity of Remembrance Day. But perhaps it is a plea to broaden our understanding of what dignity can entail. Sometimes, it looks like silent contemplation. But perhaps sometimes it looks like messy tears streaming down your face in front of strangers. Both can be powerful; both can honour the sacrifices of war.

As Ahmed notes, shared emotion can create a sense of “we.” It is why we go to movies together, cry at weddings, laugh at sitcoms in the company of others – emotional moments bond us. In this way, emotions are not just personal, they are political. In the context of Remembrance, they remind us that war is a human tragedy, felt in human hearts. Even though today, fewer families have direct ties to the armed forces, and fewer people personally know someone who has served or died in uniform, yet, the cenotaph ceremony still calls us together and asks us to care, to remember, to mourn – and it gives us permission to cry before we carry on.
