As tensions between the USA, Russia, and Ukraine continue to shape global geopolitics, European nations have committed to ramping up their defence budgets. The justification is clear: a strong military deterrent is essential in the face of unpredictable threats. However, the economic implications of these decisions extend far beyond the battlefield. Increased defence spending will require financial trade-offs, and history suggests that healthcare funding is often among the first casualties. In a world still recovering from the COVID-19 pandemic, and with global health challenges mounting, the shift in budget priorities raises pressing questions about long-term stability, economic resilience, and the unintended consequences of militarization.

The USA’s commitment to supporting Ukraine has come with strings attached. Washington has increasingly signalled that Ukraine’s vast mineral wealth — particularly its lithium, essential for batteries and renewable technologies — must play a role in repayment for aid. At the same time, President Zelensky has just last week faced pressure to demonstrate more gratitude for Western support, revealing the transactional nature of geopolitical assistance. This raises concerns about how military support agreements could influence national sovereignty and economic independence in post-war Ukraine. A growing dependence on foreign investments in resource extraction could lead to economic structures that primarily serve external interests rather than national development.

Meanwhile, European nations are making record-breaking investments in their defence sectors. Germany has pledged an unprecedented €100 billion to modernize its armed forces. The UK, Poland, and France are also significantly increasing their military budgets, with NATO countries now aiming to meet or exceed the 2% of GDP defence spending target. While some argue that such measures are necessary for deterring Russian aggression, the financial burden is immense and will require difficult policy choices. Beyond the immediate fiscal impact, increased military investments could also reshape political landscapes, with defence industries gaining greater influence over policymaking and budget allocations at the expense of social priorities.

The most immediate concern is how these expenditures will be funded. Governments will either need to increase taxation, accumulate more debt, or divert funds from other critical sectors — chiefly healthcare. In the UK, tax revenue is primarily used to fund public services, with the NHS being one of the largest recipients of government spending. In 2023, the UK government allocated around £180 billion to the NHS, accounting for roughly 40% of total public service spending. By comparison, defence spending stood at approximately £50 billion — just over a quarter of the NHS budget. However, with recent pledges to increase defence expenditure to meet NATO commitments, this proportion could shift, potentially leading to a relative reduction in NHS funding.

Public health systems across Europe, already grappling with funding crises, rising patient backlogs, and workforce shortages, face the risk of further financial strain. During the 2008 financial crisis, austerity measures led to severe cuts in healthcare funding, exacerbating disparities in care access and quality. A repeat of such measures in the current climate could prove disastrous, particularly given the ongoing pressures of an aging population, rising mental health concerns, and post-pandemic healthcare workforce burnout. Further cuts to the NHS budget could mean longer waiting times, fewer resources for frontline staff, and reduced investment in critical health infrastructure, ultimately compromising patient care.

Beyond national borders, increased military spending could also have severe consequences for global health initiatives. Many low- and middle-income countries (LMICs) rely on international aid for essential health programs. The Global Fund, Gavi, and other initiatives combatting diseases such as tuberculosis, HIV, and malaria depend on Western funding. If high-income nations shift financial commitments toward defence, these programs could suffer, leading to resurgences of preventable diseases and undermining decades of progress. Humanitarian aid, including health services for refugees and war-torn regions, may also see cuts, worsening the very instability that military spending aims to contain. A well-funded military may be necessary for geopolitical stability, but cutting global health aid could lead to greater destabilization in the long run, feeding into the very conflicts these defence budgets are designed to deter.

Yet, the argument for ramping up defence spending remains strong. The failure to bolster military capabilities could embolden Russian aggression, leading to a direct military confrontation in Europe. The economic and human cost of an unchecked conflict would be far greater than that of preventative military spending. Additionally, defence industries contribute significantly to national economies, creating jobs and technological advancements that can have spillover benefits beyond the military sector. In some cases, defence research has historically led to medical innovations, such as trauma care advancements and logistical improvements in emergency response.

The challenge, therefore, is to strike a balance — ensuring security without neglecting the broader definition of national well-being. Policymakers must explore ways to maintain robust defence funding while safeguarding healthcare investments. Potential solutions include progressive taxation policies that do not disproportionately affect social services, debt restructuring to avoid immediate austerity cuts, and the integration of health security measures — such as pandemic preparedness and medical supply chain resilience — into national security strategies. Additionally, governments should consider a broader redefinition of security that incorporates public health resilience, cyberdefence, and climate change preparedness into their strategic frameworks.

One potential approach could involve ring-fencing NHS funding from cuts, ensuring that increased defence spending does not come at the direct expense of healthcare. Another option could be targeted taxation, such as levies on high-net-worth individuals or multinational corporations, to fund defence spending without impacting essential services. Policymakers could also explore efficiency savings within existing defence budgets, ensuring that new investments in military technology do not result in unnecessary duplication or excessive procurement costs.

Ultimately, security is not just about military strength but about economic resilience, public health stability, and global cooperation. While Europe and the USA must stand firm in the face of geopolitical threats, they must also recognise that a short-sighted focus on defence spending at the expense of healthcare could weaken the very societies they seek to protect. The coming years will test whether governments can navigate these trade-offs wisely or whether they will fall into the historical pattern of prioritizing weapons over well-being. The real challenge for policymakers is not just how much to spend on defence, but how to ensure that investment in security is truly comprehensive, protecting not only borders but also the health and stability of the people within them.
