On war fighting

Why do soldiers go to war? There are a thousand different answers writes Owen, a serving soldier.

Owen is an officer in the British Army.

The car bomb went off at 0630, rudely awakening me from a deep sleep. The noise, big and bassy, was followed by silence, followed by the wailing of the camp attack alarm. I felt a range of emotions in those moments, but definitely present was a sense of relief. “So that’s what it sounds like…”. I had been in Kabul for two or three months by that point, and had always been slightly on edge whenever I walked between buildings, knowing that an explosion was inevitable at some point, but not knowing how loud it would really be. Afghanistan was my first operational tour – it was 2014 and the British presence in country was shrinking rapidly, and my reward for a good performance on my intelligence officer’s course was assignment to a unit deploying to the Afghan capital. It might seem a strange reward, but it was sincerely meant, and gratefully received. 

Why does a soldier go to war? You could ask a thousand men and women in the armed forces and get a thousand different answers. The most straightforward (and superficial) answer is “Because I was ordered to”, but delve below the surface and you find all manner of motivations and justifications. All I can offer you is why I think I wanted to join the British Army and fight (there are reasons that are probably hidden even to me) and how as Christian I make sense of war. 

I joined the Army at a time when what were known as Blair's Wars were stuttering to an unsatisfactory conclusion. We had withdrawn from Iraq, leaving behind a broken country and unwittingly paving the way for Islamic State, and soldiers were still fighting and dying in Helmand Province, Afghanistan. While I was going through the selection process for the Royal Military Academy Sandhurst there were a plethora of war documentaries on television that had been filmed using helmet cameras, giving an unprecedented first-person view of conflict. A normal person might have watched those programmes and thought they wanted no part on it whatsoever. I saw them and wanted in. Why? 

What appealed to me most was the responsibility; of deploying to a dangerous place with your fellow soldiers and doing everything in your power to keep them alive.

I look back and think there were all sorts of reasons floating round my head. There was undoubtedly a slightly boyish sense of adventure – it seemed like most of my peers at university were off to be bankers, lawyers or management consultants, and I wanted to do something a bit less grey. There was a desire to challenge myself too – a worthier reason, but still not the full story.  What appealed to me most was the responsibility; of deploying to a dangerous place with your fellow soldiers and doing everything in your power to keep them alive and to complete your mission. I saw soldiering as less a job than a calling. 

Throughout my career much has changed but that sense of responsibility is still there. It is at the heart of how I understand being a Christian in conflict zones, my personal ‘theology of war’, if you like. When I came home from Afghanistan, I was asked by a friend whether I had killed anyone. I said I hadn’t. He then asked if I thought I could bring myself to do so should the situation arise. I said that I hoped so, because I had been on armed sentry duty multiple times and so was the only person standing between my colleagues and the enemy. If I had identified a suicide bomber but decided not to shoot in that moment, then I would have been betraying the responsibility I had to my friends. Indeed, I doubt that any suicide bomber would have thought worse of me had I shot him – he would have recognised that I had my job to do, just as he had his. 

Who is anyone to judge between us, and who am I to claim the morality of what I do for a living?

Of course, this line of thinking is problematic. If I am just doing my job and the suicide bomber is doing his, then in moral terms we are surely are only as good, or as bad, as each other. His God calls him to do his duty and look after his brothers and sisters, and so does mine, and we are therefore equally right or equally wrong. Who is anyone to judge between us, and who am I to claim the morality of what I do for a living? 

And yet sincerely holding a belief does not make you right. The failings of moral relativism are well-documented, yet too often we act as the sort of people who treat Pilate’s question “What is truth?” as a viable philosophical position rather than as the moral evasion that it is. We in the West are jaded by complex and bloody counterinsurgencies with no clear end state, affirming Bart Simpson’s dictum that “There are no good wars, with the following exceptions: the American Revolution, World War II, and the Star Wars Trilogy”. But the conflict in Ukraine has shown that binary wars between an obvious aggressor and a nation defending their homeland are not merely history, and that today people can still take up arms for justifiable reason.  

I'm a Christian so I am a pacifist in the sense that peace is vastly preferable to war, and I have seen first-hand the suffering and misery it causes. Yet as a Christian too I cannot affirm peace at all costs when it means that rights and lives of innocent people can be callously disregarded by an oppressor who can only be resisted by force. I look at pictures of bombed-out apartment blocks in Ukraine, of kidnapped schoolgirls in Nigeria, of civilians murdered in Afghanistan and cannot affirm anything less than this, that there are things in this world worth fighting for.  

I would reflect too that both my calling as a soldier and my faith have given me a sense of the value of life not as something not to be clung too at all costs, but as a gift to be made the most of. One of the things we did in our first week of Sandhurst was to make a will. There I was, fresh out of university, deciding who should inherit my meagre possessions (I didn’t even have a car), and asking the bloke next to me, who I’d only met 24 hours ago, to witness my signature. To be honest, it didn’t really feel real. What felt much more real was posing for a photo in the unit sports hall two years later, arms crossed, Union Jack and regimental flag behind me, knowing that it was the photo that would be used in the newspapers if I was blown up in Afghanistan. 

You see that mutual love in tight-knit units where one soldier is prepared to die for another.

When you’re forced to confront the fact that you might die, you start to realise what it is that you are living for. I believe in the sacredness of life as a God-given gift, which makes the idea of sacrifice which lies at the heart of the Christian faith all the more powerful. “Greater love has no one than this” Jesus says in John’s Gospel, "to lay down one’s life for one’s friends”, and you see that mutual love in tight-knit units where one soldier is prepared to die for another. I think it’s that idea of living and possibly dying for something or someone more than just me is what keeps in the Army, when many of those who made their wills in that room at Sandhurst have left for civilian jobs.  

Which brings me back to my initial reflection, that there are myriad different reasons why people join the armed forces and go to war. My Christian faith is at the heart of my reason(s), but I'm realistic to know that many of my colleagues do not share that faith and so would have a different motivation (though perhaps not quite as different as one might think). We all have stories to tell about why things matter to us, and matter to us so much that we think they are worth fighting for, in whatever guise 'fighting' takes. You have heard my story. What’s yours?

Nuclear War A Scenario: the book that imagines the inconceivable

It's the most depressing book that you really need to read

Simon is Bishop of Tonbridge in the Diocese of Rochester. He writes regularly round social, cultural and political issues.

A nuclear explosion glows red and orange against the night sky.
A test explosion, 1956.

Nuclear War A Scenario (Torva, 2024) by Annie Jacobsen is about the most depressing book you could ever read and, perversely, all the more reason to read it.  Collectively, the human race has buried its head in the sand over the existence, power and proliferation of nuclear weapons. We are understandably focussed on the lasting impacts of climate change; however, nuclear war promises planetary destruction and the risks surrounding it have grown, rather than lessened, since the end of the Cold War. 

To help us focus on what we would rather not, Annie Jacobsen gives her book a plausible but hypothetical scenario. It starts with North Korea, for there we have an unbalanced, remote individual; an empathy free despot with unfettered power and unimaginable weapons at his disposal that now have the capacity to reach the east coast of the United States. 

We do not learn his reasons for launching missiles against the US in the scenario and never would, were it to happen, because Armageddon takes only minutes to unfold. Jacobsen is deeply informed round nuclear war, having talked to many highly placed American officials. One recurring anxiety she meets is that the decision to launch nuclear missiles is in the hands of the President alone and the US still operates on the so-called Launch on Warning doctrine. 

Launch on Warning means America will fire its nuclear weapons once its early warning sensor systems merely warn of an impending nuclear attack. These systems are sophisticated, but they can also be wrong, as the US discovered in 1979 when it briefly believed it was under attack from the Soviet Union. In Jacobsen’s scenario, the President has six minutes to decide what measures to take and has something approximating a menu to assist with this. Ronald Reagan observed: 

Six minutes to decide how to respond to a blip on a radar scope and decide whether to release Armageddon! How could anyone apply reason at a time like that? 

The menu, a little like ordering pizza with preferred toppings, is supposed to help with that moment. 

In Jacobsen’s scenario, US nuclear weapons are unleashed against North Korea but have to travel over Russia to get there. Russia’s early warning systems are less sophisticated and in the scenario these US missiles are believed to be an attack on Russia, not North Korea. This leads to Russia’s own uncompromising, near instantaneous response which leads to … well, you get the picture. 

A one megaton thermonuclear weapon detonates at one hundred and eighty million degrees Fahrenheit, which is four or five times hotter than the temperature at the centre of the sun and creates a fireball that expands at millions of miles an hour. This alone is unimaginable; replicating it hundreds of times over is impossible. The injuries sustained among those left; the loss of food, water, sanitation; the breakdown of law and order; the arrival of nuclear winter where temperatures plummet for decades without any infrastructure led Nikita Khrushchev to say: ‘the survivors will envy the dead’. 

Mark Lynas, a writer who for years has been helping the world to understand the science of climate change has recently turned his focus on the nuclear threat in his book ‘Six Minutes to Winter’. He observes: 

‘There’s no adaptation options for nuclear war. Nuclear winter will kill virtually the entire human population. And there’s nothing you can do to prepare, and there’s nothing you can do to adapt when it happens, because it happens over the space of hours.  It is a vastly more catastrophic, existential risk than climate change.’ 

Reaching the end of human capacity is an unsettling experience.  Solutionism is the Valley’s mantra: technology can solve every human problem, but binary thinking neglects the social, political and moral complexity of many issues and, in any case, catastrophic nuclear explosions are as likely to happen by accident as design - and could do at any time.  It’s not that we need more time for AI to resolve this existential threat; it’s that it never will. 

This is where the moral strength of faith traditions come into play as people embrace the strange hope of the powerless. Christian faith in particular cannot succumb to fatalism or the hacking of the book of Revelation to interpret the end of all things as code for nuclear war. God is creator and we are co-creators with him; we are not called to destruction when he has promised to renew the face of the earth through the resurrection of Christ.   

There is something specific about our generation. For eighty years, since the bombing of Hiroshima and Nagasaki, we have been the first generation with the capacity to destroy the whole world. Understandably, we do not want to think about this, but the fallout from this nuclear denial is that risks continue to multiply. More nations are thinking about developing nuclear weapons in an unstable world. In June 2025, the global nuclear watchdog, the IAEA said Iran was failing to meet its non-proliferation obligations for the first time in two decades and within days, Israel had launched missile strikes on Iranian nuclear sites – and many other targets – to set its nuclear programme back, followed in a significant escalation by US strikes. Nuclear weapons are a very present cause of insecurity, as the recent missile exchanges between India and Pakistan show so gravely.  

Despots watched what happened to Muammar Gaddafi after he relinquished his designs on weapons of mass destruction following pressure from western powers and are unlikely to make the same mistake. No-one can be sure the current US administration will offer a nuclear umbrella to Europe, especially when the President’s instincts are not internationalist and his preoccupation is with a golden dome shielding continental America instead.    

Almost no-one has agency in this, except for one vital piece of the puzzle: intercessory prayer, rooted in the promises of God. The ancient psalm writer prophesies: 

He makes wars cease to the end of the earth; 

He breaks the bow and shatters the spear; 

He burns the shields with fire. 

Be still, and know that I am God! 

I am exalted among the nations, 

I am exalted in the earth. 

And something greater than the spear is among us today.
