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.

Christine Schliesser lectures in Theology and Ethics at Zurich University, and is a scientific collaborator with the Center for Faith & Society at Fribourg University.

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.

As algorithms divide us, who should we be loyal to?

An ethicist’s answer, shows we need courage and wisdom too.

What is loyalty? As we plunge into this new year of 2025 it seems as pressing a question as ever. The war in Ukraine rumbles on, a fresh Labour government continues to struggle with public opinion, and America returns to the unpredictable rule of the first president in its history to be a convicted felon. The algorithms of social media continue to segregate and amplify different audiences into ever more closed feedback loops and echo chambers. This may bolster loyalty to a point of view, but estrange us further from our friends and neighbours whose loyalties lie elsewhere. All of these and many other cases highlight the conflict of loyalties in our society and wider world. What is even more obvious is that if we are to make peace, cultivate love for enemies, and pursue the common good, then perhaps the most in-demand virtue of 2025, at the top over every wish list, might just be loyalty.  

But what really is loyalty?  

I was struck by a persuasive answer given by Dr Tony Milligan, research fellow in philosophical ethics at King’s College London, during his appearance on a recent episode of The Moral Maze on BBC Radio 4 that asked ‘is loyalty a virtue or a vice?’ He said loyalty is, “Sharing another person’s commitments and the willingness to go through various kinds of adversity in order to pursue those commitments and to further them.” Under cross examination and asked if loyalty is then an absolute virtue he responded, “I think that it’s absolute in the sense that we absolutely need to have it, that it’s basic to the human condition and not optional.” His second interrogator, Giles Fraser, then suggested a ‘high doctrine of mates’. In this doctrine you are loyal to your mates in all circumstances, even if they are ‘wrong-uns’. Dr Milligan’s response, when asked how he would characterise this ‘doctrine of mates’ position, was fascinating: “Addiction.” Fraser then asked if that addiction could be love. “It’s a case of love, and we don’t get to choose the people that we love. We find ourselves in the predicament and then try to make the best of it…I love my wife Susanne, I’ve been with her 31 years, and it’s love, and it’s also addiction. I just can’t envisage a world in which I would be without her.” This framed Dr Milligan’s final powerful point: love, and the loyalty which love entails, gives us our sense of value.  

I can bear witness to the truth of Dr Milligan’s intertwining of love and loyalty. Last autumn I became a father for the second time. My love for my eldest is so great that there was a real question: ‘if my love for my eldest is so total, so all encompassing, how can I possibly love a second as much?’ This question melted away as I gazed into her screwed-up face, moments after she entered the world. I am completely dedicated to ensuring that she flourishes and I would “go through various kinds of adversity in order to pursue” her flourishing. As Dr Mulligan also said, loyalty “is basic to the human condition and not optional.” Of course, how this total and non-zero-sum loyalty of love to both of my children actually works in practice requires of me thoughtful negotiation. If one wants to go to the park and the other wants to go to the swimming pool I cannot split in two and do both things at once. Loyalty, as finite human beings, requires wisdom in living in the middle of a messy network of demands and desires, of the preferences and needs of others. 

If loyalty is then one thing, it is the willingness to recognise that we are tied to other people, whether we like it or not. Cain’s question to God, when God came looking for Abel, is still pertinent: “Am I my brother’s keeper?” Perhaps the greatest disloyalty is the implied ‘no’ in Cain’s rhetorical question. In denying that he is bound to his brother he is disloyal not only to Abel, but to himself because he denies his own humanity and isolates himself from the humanity of other people. If we isolate ourselves, having loyalty only to ourselves, we lose the joy of being fully human. If we simply kill those we dislike, whether literally (in war or murder) or metaphorically (‘unfriending’, cancelling, pretending they do not exist), then we follow Cain. Loyalty, as the tie that binds us to the messiness of the real world where people vehemently disagree all the time, requires not only wisdom then but courage also. It takes courage to commit to one person in marriage. It takes courage to raise a child. It takes courage to continue to talk with and to love those with whom you deeply disagree.  

When practising our 2025 New Year’s resolutions let us make sure that amongst the commitments to get back to the gym and practice that new hobby that we remember to practice loyalty. Loyalty not only to those we love, but to those we might come to love. Let us be wise enough and brave enough to be fettered to those with whom we disagree, loyal to the humanity that binds us together.
