Oppenheimer, my father, and the bomb

One week after its release, Christopher Nolan's latest blockbuster has left Luke Bretherton pondering an un-resolved disagreement with his late father and the theology of Oppenheimer's creation.

Luke Bretherton is a Professor of Moral and Political Theology and senior fellow of the Kenan Institute for Ethics at Duke University in Durham, North Carolina.

I went to see the film Oppenheimer on its opening night at my local, community run cinema in Acton in west London. It was packed. The event felt more like going to church than to the movies. The film itself is a biopic of scientist Robert J. Oppenheimer who was a pivotal figure in leading the development of nuclear weapons during World War II.

Reflecting on the film afterwards it brought to mind a difficult and never resolved argument with my late father. In the aftermath of watching the film, I realised I was still haunted by our dispute.

Our argument centred not on whether it was right to drop the bomb. Our argument was about whether it was Christian.

My father was 18 in 1945 when atomic bombs were detonated over the Japanese cities of Hiroshima and Nagasaki, killing over 200,000 souls. He was conscripted into the British Army that year and stationed in India. If the war had not ended, he would have been among those deployed to invade Japan.

Our argument was not just about whether it was right to drop the bomb. It was also about whether it was Christian. My father was an ardent believer who converted to Christianity in the 1950s. His Christian commitments deeply shaped every aspect of his life and work. I followed in his footsteps, and at the time of our argument I was doing a PhD in moral philosophy and theology. In part I was trying to make sense of what it meant to be a Christian in the aftermath of events like the Holocaust and the dropping of nuclear weapons over Hiroshima and Nagasaki, events in which it seemed Christian beliefs and practices played a key part. In the film, this is marked by the stark symbolism of Oppenheimer naming the first test of the prototype nuclear weapon “Trinity” – an often used and key way in which Christian name God.

I had been learning about just war theory when the argument with my father erupted. I was having dinner with my mum and dad at their house. To give a bit of context, my father and I had a long history of sometimes bitter arguments over political matters. These began in the 1980s when I was a teenager. He thought Mrs Thatcher a hero. I did not.

I was telling them about just war theory and its history in Christian thought and practice. As with most of our arguments, we stumbled into it. I made a throwaway remark about how, in the light of just war theory, nuclear weapons were immoral and that their use in 1945 was wrong. And yes, I was probably being pompous and annoying like all those possessed of a little new knowledge and a lot of self-righteous certitude and fervour.

My dad replied with anger that I did not know what I was talking about. Didn’t I realize that if the bombs hadn’t been dropped many more would have died, including him, which meant I would not exist. Something like this argument was used in the film and was often used by Oppenheimer to justify his own involvement in developing atomic weapons.

At the time, I replied with a procedural point that nuclear weapons do not distinguish between combatants and non-combatants, a key distinction in determining the morality or otherwise of targets in war. To use nuclear weapons is to deliberately intend the indiscriminate killing of the innocent. This constitutes murder and not, as the euphemism has it, unintended collateral damage. I added insult to injury by declaring that my dad’s argument was also deeply unchristian as it was a version of the ends justify the means. Was it ever right to do evil even if good might be the result? This upset my father still further. For him it was personal. It was existential. The bombs saved his life. The bombs made our life possible.

The meal, like the argument, did not end well. We had both upset my mother. She banned us from ever talking politics at the family dinner table again. It was a lifetime ban.

What dawned on me was that the question of whether it was moral to possess, let alone use, nuclear weapons was also an existential question for me. 

Afterwards I thought more about our row. I replayed the script in my head, trying to think of what I should have said. In my immaturity, I never thought to consider how I should have said it.

What dawned on me was that the question of whether it was moral to possess, let alone use nuclear weapons was also an existential question for me. It was a question of what kind of existence warranted anyone possessing nuclear weapons. To use the language of the Cold War of which I was a child: was it better to be red than dead? Was it better to be invaded and taken over by Communists and see capitalism abolished and the British nation subordinated to a foreign power or to deter this possibility by possessing nuclear weapons, weapons that threatened to destroy all life on this planet? In other words, was my way of life really worth the threat of nuclear annihilation. Was any way of life or ideology or commitment or abstract principle worth that? I concluded that it was not and promptly joined the Campaign for Nuclear Disarmament (CND).

I have not attended a CND rally for many years. And what happened in 1945 is more complicated than I used to think. But I still disagree with my dad and think Oppenheimer was deeply misguided. And what happened after 1945 with the advent of the nuclear arms race is not complicated. The film portrays Oppenheimer as anticipating and trying to forestall the process of one-upmanship that developing the A-bomb and then the H-bomb set in motion. He was right to do what he could to stop the arms race, even though, as the film portrays, the authorities tried to silence and marginalize him for his efforts.

Today, if my father and I were able to have the argument again, I would approach it very differently. I hope I would be less pompous, annoying, and self-righteous. But mostly, I would be more theological. I would ask him whether he thought Jesus would drop a nuclear bomb to save a life, or whether Jesus’s own life, death, and resurrection pointed in a different direction. And then see where that conversation took us.

Viruses don’t respect borders and nine other reasons why aid is vital for security

Cuts are a dangerous false economy.

 The Minister for International Development Anneliese Dodds took the difficult step to resign following the Prime Minister’s announcement this week that he is slashing the aid budget to pay for more weapons. Minister Dodds wrote in her resignation letter that:  

“Ultimately, these cuts will remove food and healthcare from vulnerable people." 

The hefty reduction in our international aid budget does indeed put lives at risk around the world. However, the move also serves to undermine our own national security. A strong UK presence on the world stage comes not primarily through military strength but through diplomacy and targeted development funding.  

General Lord Dannatt, former Chief of the General Staff, commented: 

“In the wider world, it’s disappointing that we’re probably going to plunder the international development budget, because the UK’s influence in the world often comes through a combination of our hard power and our soft power, our diplomacy and our development funds.” 

International aid is proven to be one of the most effective ways to build prosperity and peace. It is a strategic investment in national and international security, arguably more useful and cost-effective than military defence spending.  

Cutting aid budgets may release funds in the short term, but in reality, it weakens Britain’s influence, undermines global stability, and increases security risks. It is not only false economy, but a potentially dangerous and counterproductive shift in policy.   

Here are ten reasons why international aid is such a crucial investment in security: 

1. Addressing root causes reduces terrorism.

Foreign aid helps foster peace, reduce poverty, and support development in the most vulnerable regions. When countries are stable, they are less likely to fall into chaos or become breeding grounds for terrorism and extremism. UK-funded education initiatives in Pakistan and Somalia, such as the Girls’ Education Challenge, have provided over 1.5 million marginalized girls with schooling, reducing the vulnerability of young people to extremist recruitment. By decreasing the appeal of radicalization, this investment has contributed to lowering the long-term threat of terrorism against British citizens at home and abroad. 

2. Investing in global health reduces pandemic risks.  

Viruses don’t respect borders. Our funding for Ebola response in West Africa has helped prevent global outbreaks, reducing the risk of deadly diseases spreading to the UK. Similarly, by investing in vaccinations against new strains of Covid around the world, Britain has strengthened its own pandemic preparedness and safeguarded public health at home. 

3. Stronger relationships between nations reduce conflict 

Post civil war UK support for Sierra Leone helped train police and government officials, strengthening long-term diplomatic ties and preventing a return to instability that might have spilled across the continent. This has also helped position the UK as a trusted diplomatic partner in West Africa, leading to trade agreements and political alliances that benefit Britain’s global interests. 

4. Supporting stability reduces forced migration.

It is now acknowledged that it is building anchors, not walls, that is the best strategy to curb migration. The UK Aid Direct programme has provided economic and social support in countries like Syria, Lebanon, and Afghanistan, reducing forced displacement and lowering pressure on UK border security. By stabilizing regions affected by conflict, Britain has been able to reduce illegal migration and the associated costs of border enforcement, asylum processing, and emergency housing. 

5. Promoting sustainability reduces resource scarcity due to climate change.  

The UK International Climate Finance (ICF) initiative supports sustainable agriculture and clean energy projects in Africa and Asia, mitigating competition over dwindling resources and preventing climate-driven conflicts that have contributed to making the world a more turbulent place. This has not only improved global stability but has also created opportunities for UK businesses in the green energy and sustainable development sectors. 

6. Building resilience reduces international crime and instability.  

UK funding has been instrumental in stabilizing Somalia, for example, improving their governance, training law enforcement, and reducing crime and piracy that threaten not only international shipping but tourism too. As a result, British shipping companies and tourists traveling in the region have faced fewer security risks, boosting confidence in UK-led trade and travel. 

7. Preventing famine and malnutrition reduces political instability.

The UK-funded Famine Early Warning Systems Network (FEWS NET) has helped prevent food crises in East Africa, reducing the likelihood of mass migration and conflict over resources. Without that investment, Britain would have likely spent far more on emergency humanitarian relief and crisis management, demonstrating the cost-effectiveness of preventative aid. 

8. Building stronger economies abroad creates opportunities.  

UK trade-focused aid, such as through the Prosperity Fund, has helped African nations develop stable economies, creating trade opportunities for Britain while reducing dependence on fragile states. Stronger economies in partner countries mean increased demand for British exports, benefiting UK businesses and job creation. 

9. Humanitarian aid strengthens a nation’s global influence.

The UK has been a major donor in response to the Rohingya refugee crisis, contributing £350 million to support displaced people in Bangladesh and Myanmar—enhancing Britain’s standing as a global humanitarian leader and leading to soft power advantage on the global stage. This goodwill has translated into stronger diplomatic relations with key allies in South Asia, supporting UK interests in trade, security, and regional stability. 

10. Disaster response builds goodwill and strategic partnerships. 

Following the 2010 Haiti earthquake, the UK provided £20 million in emergency aid, strengthening ties with Caribbean nations and showcasing Britain’s global leadership in crisis response. These efforts have reinforced Britain’s role as a reliable partner in times of crisis, leading to closer economic and diplomatic relationships with countries across the Caribbean. 

If the West vacates aid funding it creates a very significant vacuum into which other countries will step. For example, Russia has already sent Wagner mercenaries to patrol the Central African Republic and Mali. This is not only bad for the citizens of those areas, but also from a UK national security perspective. It would be extremely concerning if the Russian state were able to build a sweeping base of influence and soft power in the global South. 

With an increasingly fragile world, the tool that is most useful for national security at this time is international aid. The rise in conflict, migration, terrorism and other pre-war conditions is directly due to the impact of poverty – which now affects 44 per cent of the global population, wealth concentration – which increases the chance of financial crises, weakened trade routes – due to Brexit, war in Ukraine and the Middle East, and new tariff policies in the US, and climate change – which exacerbates all those tensions.  If the UK want an effective defence strategy in these turbulent times, we must reconsider doubling down on our international aid commitments, not abandoning them.
