Swords now, ploughshares later

There’s a moral case for investing in defence capabilities right now.

It is two years since the Russian invasion of Ukraine, on 24 February 2022. We are still sleep-walking, with the British public and political class yet to grasp its implications. The risks of large-scale conflict have surged, and the British military is inadequately prepared for the operations it may soon be called on for. One day, swords will be turned into plowshares. But right now, in this imperfect world, we need more swords. Even if not widely enough, some have realised that the global order has changed. But fewer still are willing to act on that realisation.  

The Russian assault in February 2022 was designed to shock. Repeating the plan which the Soviet Union had used in Afghanistan in December 1979, armoured columns advanced on the capital on multiple axes, preceded by an aviation assault into an airport just outside the main capital, intended to allow invading forces to ‘decapitate’ the government. The 2022 attack was also accompanied by strikes on key targets in Kyiv itself, with Russia mimicking the ‘shock and awe’ campaign with which coalition forces had initiated the invasion of Iraq in 2003.  

The international situation has been parallel, with an immediate shock, galvanising intensive and often heroic action—but the resolve for which has withered with time. Some moments of demonstrated resolve among the public during the early months stand out in my memory. The students in Oxford who were fundraising not just for blankets for refugees, but for body armour, night-vision goggles and, if I remember rightly, even weapons. The stranger who bought a decrepit caravan from me for scrap saying, quietly and undemonstratively, that she would not buy fuel from Shell because it was blood oil. And, the 12-foot-tall statue in Oxford’s Broad Street of a Ukrainian soldier expressing the city’s solidarity.  

This was echoed at the national level. In a welcome act of leadership, Boris Johnson, then Prime Minister, declared that Putin “must fail and must be seen to fail”. This gave the necessary direction for a series of forward-leaning policies, both economic and military, to support Ukraine.  

The shock was short-lived, however, and in its place are concerning questions about both public and political resolve. The underlying issue is the significance of the Russian invasion of Ukraine. While the immediate consequences of this conflict are felt by Ukrainians, it matters more widely—to both the British and the global public. Realising these consequences, and then taking the appropriate action to address them, is now urgent. That action involves serious investment in defence industries, defence capability, and the military.  

The lights on the dashboard of global security are all flashing—some amber, and some red. 

The Russian invasion of Ukraine matters more widely in at least the following four ways. 

First, it has incurred immediate costs on consumers globally. This sounds bland but is not. Soaring energy bills have cost lives, with the Economist estimating that the war indirectly killed more people in Europe in winter 2022 than Covid-19 did; so too do soaring food costs in countries which desperately need a steady, cheap supply of grain.  

Second, the current course of the conflict in Ukraine has dramatically raised the risk of a confrontation between NATO and Russia, which may include either or both of conventional or hybrid conflict. Russia has not succeeded in turning Kyiv into a satellite state. But, unless NATO dramatically increases its supply of materiel, including high-end capabilities, the most likely outcome of the war is that Russia will successfully ‘freeze’ the conflict while controlling approximately a fifth of Ukraine, including the most economically productive part of the country in the East. Such success increases the likelihood of a revanchist Putin, seeking to establish Russian control over its claimed ‘historic’ borders and having put his economy on a war footing, attacking perhaps the Baltic states. Or Russia may simply seek to disrupt NATO countries in forms of conflict that fall short of conventional war, but risk escalation, as witness the recent Estonian arrests of ten people alleged to be part of a Russian destabilisation operation. The collective self-defence pact embodied in NATO’s Article 5 means that UK forces will be involved in any response to such aggression. 

Third, the current inability for the US and Europe to act decisively, due to domestic political irresolution and polarisation, in the face of a clearly deteriorating security environment, emboldens potential adversaries. This is evident daily at the moment, with Republican politicians refusing to approve the $60 billion support package for Ukraine proposed by the Biden administration; as a result, the Ukrainian army has just withdrawn from Avdiivka, because it lacks the artillery shells to defend it. In a post-2016 timeline, and from an external perspective, the West now looks decadent.  

Fourth, that Russia is likely to succeed in its war aims (unless something changes on the battlefield) further undermines the norms of non-aggression which are central to our currentrules-based international order. The domestic political trajectories of Russia, China, and Iran are not presently encouraging. All have stated goals which would see change in who controls relevant territories, and none rule out the use of force in achieving their goals.  

The Russian invasion of Ukraine in February 2022, then, is an inflection point. The lights on the dashboard of global security are all flashing—some amber, and some red.  

But Javelins do not descend ex nihilo from the clouds: they need to be manufactured by advanced industries.  

In the face of such a deteriorating security environment, the urgent task for a responsible government is to ensure that it has the required military capability. This capability must be at minimum sufficient to defend its own citizens. It must also be sufficient to protect more widely those whom it has undertaken treaty commitments to defend. And, as a contribution to the wider public good, it is desirable that that capability should be sufficient to defend other innocent parties globally, subject to appropriate authorisation. Central to this capability is having a defence industry which will develop and manufacture the arms required.  

The defence industry has frequently attracted criticism and controversy, with the most damaging charge being that it sells weapons to authoritarian regimes in corrupt deals. Exporting arms to regimes that will use them repressively, through corrupt contracts, is plainly wrong. But responding to this criticism does not require banning or otherwise abolishing the defence industry. Rather, the correct response is to reform it and then regulate it effectively, on the grounds that if war itself can sometimes be just, then the production of the tools required for war must itself be just.  

If the state is, as St Paul had it, commissioned to punish the wrongdoer, ‘not bearing the sword in vain’, someone must make the swords. 

The Russian invasion of Ukraine in 2022 was a paradigm of wrongful aggression; if war is ever justified as, I think, an imperfect world forces us to accept, it is in such circumstances. Those who would contest such aggression, in defence of innocent lives and sovereign states, need the weapons to be able to do so, and they need the best weapons that are available. One of the immediate actions that Ben Wallace, then UK Secretary of State for Defence, took in response to the invasion was to surge Britain’s stocks of man-portable anti-tank weapons to Ukraine. One of these, the Javelin weapon, literally gained iconic status, in the meme of ‘St Javelin’, styled as an Orthodox saint. But Javelins do not descend ex nihilo from the clouds: they need to be manufactured by advanced industries.  

The defence industry, then, may certainly play a valuable role in a country’s economy. But more than that, in a world of predatory and repressive states, and violent non-state actors, it is a moral necessity. Isaiah foresaw, prophetically, a time when swords will be turned into ploughshares and spears into pruning hooks. But this side of that new reality, we need states that protect the innocent, and without a defence industry to equip the state to do so, the innocent lie vulnerable. If the state is, as St Paul had it, commissioned to punish the wrongdoer, ‘not bearing the sword in vain’, someone must make the swords. The peace dividend at the end of the US-Soviet Cold War has been spent, and we are in ‘the foothills’ of a new one, as the late Henry Kissinger described it. Ploughshares later; it must be swords now.  

How long have we got? It is a basic principle of military planning that, while you should structure your own operations around the enemy’s most likely course of action, you should also, and crucially, have contingencies for the enemy’s worst-case course of action. That worst-case may be with us sooner that we think. In the lead-up to the recent Munich Security Conference, the Estonian intelligence chief estimated that Russia is preparing for confrontation with the West ‘within the next decade’; the chair of Germany’s Bundestag defence committee indicated five to eight years; and the Danish defence minister suggested three to five years.  

With procurement timelines for advanced equipment—such as main battle tanks, frigates, and next generation fighter aircraft—typically taking over a decade, the urgent priority is for defence investment now. The UK’s Armed Forces are in a parlous state, as the recent cross-party report by the House of Commons Defence Committee makes clear. This investment in defence will not be cheap, and the difficult political task is deciding what spending to cut to allow for this uplift. But this debate cannot wait, and politicians must lead the country now in the required mind-set shift. Poland is the only NATO country to have convincingly demonstrated that it understands the times we live in, by investing seriously in its army. The UK government certainly wills the end, of ensuring the country’s security. The present question is whether it wills the means.

Ethics needs to catch-up with genetic innovation

Are we morally obliged to genetically edit?

It makes me feel very old when I realise that Louise Brown, the first baby to be born via in vitro fertilisation (IVF), will be 47 years old on July 25th this year. Since her birth in 1978, over 10 million IVF-conceived babies have been born worldwide, of whom about 400,000 have been in the UK. Over that period, success rates have increased such that in some clinics, about 50 per cent of IVF cycles lead to a live birth. At the same time, there have also been significant advances in genetics, genomics and stem cell biology all of which, in relation to human embryos, raise interesting and sometimes challenging ethical issues. 

I start with a question: what is the ‘moral status’ of the early human embryo? Whether the embryo arises by normal fertilisation after sexual intercourse or by IVF, there is a phase of a few days during which the embryo is undergoing the earliest stages of development but has not yet implanted into the wall of the uterus; the prospective mother is not yet pregnant. In UK law, based on the Human Fertilisation and Embryology Act (1990), these early embryos are not regarded as human persons but nevertheless should be treated with some respect. Nevertheless, there are some who oppose this view and believe that from the ‘moment of conception’ (there actually isn’t such a thing – fertilisation takes several hours) embryos should be treated as persons. In ‘conventional’ IVF this debate is especially relevant to the spare embryos that are generated during each IVF cycle and which are stored, deep-frozen, in increasing numbers for possible use in the future.  

A further dimension was added to this area of debate when it became possible to test IVF embryos for the presence of genetic mutations that cause disease. This process is called pre-implantation genetic diagnosis and enables prospective parents who are at known risk of passing on a deleterious mutation to avoid having a child who possesses that mutation. But what about the embryos that are rejected? They are usually discarded or destroyed but some are used in research. However, those who hold a very conservative view of the status of the early embryo will ask what right we have to discard/destroy an embryo because it has the ‘wrong genes’. And even for the many who hold a less conservative view, there are still several questions which remain, including ‘which genetic variants we should be allowed to select against?; should we allow positive selection for genes known to promote health in some way?’; should we allow selection for non-therapeutic reasons, for example, sporting prowess?’ These questions will not go away and there are already indications that non-therapeutic selection is being offered in a small number of countries. 

Genetic modification 

This leads us on to think about altering human genes. Initially, the issue was genetic modification (GM) which in general involves adding genes. GM techniques have been used very successfully in curing several conditions, including congenital severe immune deficiency and as part of treatment programmes for certain very difficult childhood cancers. One key feature of these examples is that the genetic change is not passed on to the next generation – it just involves the body of someone who has already been born. Thus, we call them somatic genetic changes (from the Greek, sōmatikos, meaning ‘of the body’).  

Genetic modification which is passed on to the next generation is called germline GM which means that the genetic change must get into the ‘germ cells’, i.e., the sperm or egg. Currently, the only feasible way of doing this is to carry out the genetic modification on the very early embryo. At present however, with just one very specific exception, GM of human embryos is forbidden in all the countries where it would be possible to do it. There is firstly the question of deciding whether it is right to change the genetic makeup of a future human being in such a way that the change is passed to succeeding generations. Secondly, there are concerns about the long-term safety of the procedure. Although it would involve adding specific genes with known effects, the complexity of genetic regulation and gene interactions during human development means that scientist are concerned about the risks of unforeseen effects. And thirdly, germline GM emphasises dramatically the possibility of using GM for enhancement rather than for medical reasons.  

Genome editing 

This leads us to think about genome editing. In 2011, it was shown that a bacterial system which edits the genomes of invading viruses could also work in other organisms This opened up a large array of applications in research, agriculture and medicine. However, the ethical issues raised by genome editing are, in essence, the same as raised by GM and so there is still a universal prohibition of using the technique with human embryos: germline genome editing is forbidden. Despite this, a Chinese medical scientist, He Jiankui, announced in 2018 that he had edited the genomes of several embryos, making them resistant to HIV; two babies with edited genomes had already been born while several more were on the way. The announcement caused outrage across the world, including in China itself. He Jiankui was removed from his job and then, after a trial, was imprisoned for three years; his two colleagues who collaborated in this work received shorter sentences. 

At present the universal prohibition of human germline genome editing remains in place. However, the discussion has been re-opened in a paper by an Anglo-Australian group.  They suggest that we need to develop heritable (i.e. germline) polygenic genome editing in order to reduce significantly an individual's risk of developing degenerative diseases. These includecoronary artery disease, Alzheimer’s disease, major depressive disorder, diabetes and schizophrenia. I note in passing that one of the authors is Julian Savulescu at Oxford who is already well-known for his view that parents who are able to do so, are ‘morally obliged’ to seek to have genetically enhanced children, whether by PGD, GM or genome editing. The use of polygenic editing, which would, in all likelihood, be available only to the (wealthy) few, fits in well with his overall ethical position. Needless to say, the paper, published in the prestigious journal Nature, attracted a lot of attention in the world of medical genetics. It was not however, universally welcomed – far from it. Another international group of medical scientists and ethicists has stated that ‘Human embryo editing against disease is unsafe and unproven …’ and even go as far as to suggest that the technology is ‘… going to be taken up by people who are pushing a eugenics agenda …’ remain very pertinent. 

Harder still and harder 

I have no doubt that amongst different reader there will be a range of opinions about the topics discussed so far. For anyone who is Christian (or indeed an adherent of almost any religious faith), one of the difficulties is that modern science, technology and medicine have thrown up ethical questions that could not have even been dreamed of by the writers of the Bible (or of other religious texts). We just have to use our wisdom, knowledge and general moral compass (and for some, prayer) to try to reach a decision. And if what I have already written makes that difficult, some recent developments multiply that difficulty still more.  

In the early years of this century, scientists developed methods of transforming a range of human cells into ‘pluripotent’ stem cells, i.e., cells capable of growing into a wide range of cell types. It also became possible to get both induced stem cells and natural stem cells to develop into functional differentiated cells corresponding to specific body tissues. This has huge potential for repairing damaged organs. However, other applications are potentially much more controversial. In 2023, Cambridge scientists reported that they had used stem cells to create synthetic mouse embryos which progressed at least as far as brain and heart formation within the normal pattern of mouse embryo development. 

At about the same time, the Cambridge group used individual human embryonic stem cells (from the blastocyst stage of embryonic development), to ‘grow’ early human embryos in the lab. There is no intention to use these embryos to start a pregnancy – indeed, it would be illegal to do so – but instead to study a period of embryo development which is not permitted with ‘real’ human embryos (research must not continue past 14 days of development). But how should we regard synthetic embryos? What is their moral status? For those who hold a conservative view of the normal human embryo (see earlier), should we regard these synthetic embryos as persons? Neither does the law help us. The legal frameworks covering in vitro fertilisation and early embryos (Human Fertilisation and Embryology Acts, 1990, 2008) do not cover artificial embryos – they were unknown at the times the legislation was drawn up. Indeed, synthetic embryos/embryo models are, in law, not actually embryos, however much they look like/behave like early embryos. Earlier this month, the Human Fertilisation and Embryology Authority (HFEA) discussed these developments with a view to recommending new legislation, but this will not dispel an unease felt by some people, including the science correspondent of The Daily Telegraph, who wrote that this research is irresponsible.  

But there is more. In addition to synthetic embryos, the HFEA also discussed, the possible use of gametes – eggs and sperm – grown from somatic stem cells (e.g., from skin) in the lab. Some authors have suggested that the production of gametes in vitro is the ‘Holy Grail’ of fertility research. I am not so sure about that but it is clear that a lot of effort is going into this research. Success so far is limited to the birth of several baby mice, ‘conceived’ via lab-grown eggs and normal sperm. Nevertheless, it is predicted that lab-grown human eggs and sperm will be available within a decade. Indeed, several clinicians have suggested that these ‘IVGs’ (in vitro gametes) seem destined to become “a routine part of clinical practice”.  

The lab-grown gametes would be used in otherwise normal IVF procedures, the only novelty being the ‘history’ of the eggs and/or sperm. Clinicians have suggested that this could help couples in which one or both were unable to produce the relevant gamete, but who still wanted to have children. In this application, the use of IVGs poses no new ethical questions although we may be concerned about the possibility of the gametes carrying new genetic mutations. However, some of the more wide-ranging scenarios do at the least make us to stop and think. For example, it would be possible for a same-sex couple to have a child with both of them being a genetic parent (obviously for males, this would also involve a surrogate mother). More extremely, a person could have a child of which he or she was actually, in strictly genetic terms, both the ‘father’ and the ‘mother’. What are we to make of this? Where are our limits?  

Dr Christopher Wild, former director of International Agency for Research on Cancer, explores in depth many of the developments and issue I outlined above. His article on why a theology of embryos is needed, is clear, well-written, helpful and thought-provoking.
