Global priorities are shifting and healthcare is paying the price. The world is entering one of the most consequential yet under-discussed public health crises of our time. Not driven by a pandemic or a breakthrough disease, but by a deeper, systemic force—the steady diversion of resources away from health and toward geopolitical priorities. As governments recalibrate budgets amid escalating conflicts and economic uncertainty, healthcare systems, particularly in low- and middle-income countries (LMICs), are bearing the brunt.
Behind every budget shift lies a ripple effect, and today, global healthcare is at the receiving end. The result is shrinking access, rising costs, and widening inequities. The impact of geopolitical decisions is rarely confined to borders, it now extends into clinics, hospitals, and communities. What we are witnessing is not just a funding gap, but a structural shift in how the world values health.
The silent reallocation
Over the past years, global defense spending has surged to record levels. According to the Stockholm International Peace Research Institute (SIPRI), global military expenditure rose by 9.4% in real terms to $2718 billion in 2024, the highest global total ever recorded by SIPRI and the 10th year of consecutive increases. The total military expenditure accounted for 2.5% of the global gross domestic product (GDP) in 2024. These figures are expected to climb further following the June 2025 commitment by North Atlantic Treaty Organization (NATO) members to increase defence and security spending to 5% of GDP by 2035, more than twice the earlier 2% benchmark.
Meanwhile, public health budgets are being trimmed or stagnating. The World Health Organization (WHO) has raised serious concerns about the strain on global health systems, pointing to shrinking international aid and ongoing funding shortfalls. In February, Director-General Tedros Adhanom Ghebreyesus highlighted that abrupt and significant reductions in bilateral assistance have severely disrupted healthcare services across multiple countries, describing 2025 as “one of the most challenging years” in the organization’s history.
As per the WHO, an estimated 4.6 billion people worldwide still do not have access to essential health services, while around 2.1 billion experience financial strain due to healthcare expenses. Compounding this challenge, the global health workforce is projected to face a shortfall of 11 million professionals by 2030, with nurses accounting for more than half of this gap. When 4.6 billion people lack access to essential services, this is not only a development failure, but also a global stability risk – translating into fewer vaccinations, delayed disease surveillance, and weakened emergency response systems.
The global policy conversation increasingly treats defence spending as essential security investment. Health spending, however, is still framed as social expenditure rather than strategic infrastructure. This shift is particularly devastating for LMICs, where international aid often fills critical gaps.
Conflict and the collapse of care
Conflict has long been a stress test for health systems, but the consequences today are deeper and more far-reaching. As the Russia–Ukraine war entered its fifth year in 2026, Ukraine’s health system faced unprecedented strain, with attacks on healthcare rising nearly 20% in 2025 alone. Since the full-scale invasion began, the WHO has documented at least 2,881 attacks targeting hospitals, health workers, ambulances, and medical infrastructure, severely disrupting care delivery. Health outcomes have deteriorated sharply, with 59% of people in frontline areas reporting poor health, alongside surging mental health issues, cardiovascular conditions, and widespread lack of access to essential medicines. Intensified attacks in 2025, including a spike in strikes on medical warehouses, have further crippled supply chains.
In the aftermath of the war in Gaza, the region’s health system remains on the brink of collapse despite months of humanitarian efforts and intermittent pauses in fighting. Widespread damage to hospitals, severe shortages of medicines, and a surge in patients continue to overwhelm already fragile services. Many facilities operate at drastically reduced capacity, with critical treatments, including cancer care, meeting only a fraction of demand, while rising cases of skin and respiratory illnesses place further strain on the system. Healthcare workers, operating under extraordinary pressure and with limited resources, are struggling to manage overwhelming caseloads each day amid ongoing supply constraints and infrastructure damage. The crisis extends well beyond acute injuries, as patients with chronic illnesses face dangerous interruptions in care and deteriorating living conditions, turning access to healthcare into a daily struggle for survival.
Meanwhile, after three years of conflict, the Sudan war has evolved into the world’s largest humanitarian and health crisis, with 34 million people in need of aid and 21 million lacking access to basic healthcare. The system is collapsing under the combined weight of widespread disease outbreaks, acute malnutrition affecting over 4 million people, and relentless attacks on healthcare infrastructure—37% of facilities are now non-functional. As infectious diseases surge and funding falls short, Sudan’s health crisis continues to deepen, turning basic healthcare access into a matter of survival for millions.
What distinguishes the current moment is the scale of global interdependence. Earlier crises were largely contained within regions. Today, disruptions are transmitted across borders through tightly integrated supply chains, financing systems, and health workforces. The Ukraine conflict, for instance, has affected global pharmaceutical logistics and energy prices, indirectly increasing healthcare costs across Europe, Asia, and beyond. The result is not just localized breakdowns, but a systemic fragility in global health security.
Conflict as a cost multiplier in health delivery
Healthcare systems are tightly linked to global supply chains, making them highly vulnerable to geopolitical disruptions. When conflicts interrupt trade routes, restrict exports, or trigger sanctions, costs rise almost immediately, across pharmaceuticals, medical devices, and even basic supplies.
Energy shocks add further pressure. Hospitals, being energy-intensive, face higher operating costs as fuel and electricity prices climb. In conflict zones, even critical functions like vaccine cold chains and intensive care become difficult to sustain. The result is a steady increase in healthcare costs, one that is unevenly felt. While high-income countries may cushion the impact through insurance and subsidies, LMICs face a harsher reality, where rising out-of-pocket expenses can push millions into poverty.
At the same time, conflicts are driving up demand for care. Displacement, malnutrition, and infectious disease outbreaks are becoming more frequent, often compounded by climate-related crises. This creates a vicious cycle. Underfunded systems struggle to respond, outcomes worsen, and long-term costs escalate as preventable issues turn into full-blown crises.
Health communicators bridging gaps in a fragmented world
In times of systemic stress, communication becomes a strategic imperative. Health communicators are no longer just interpreters of science. They are interpreters of risk, resilience, and national preparedness. Their role is to translate complex realities into actionable understanding, to advocate for evidence-based decision-making, and to maintain trust in institutions. In today’s environment, narrative gaps are becoming policy gaps. When health is absent from security conversations, it is often absent from security budgets.
In the current context, communicators must:
- Elevate the narrative around health as a security priority, not a secondary concern.
- Highlight the human impact of budget cuts, moving beyond statistics to real stories.
- Counter misinformation proactively, especially in conflict-affected and resource-constrained settings.
- Support policy advocacy, ensuring that health remains central in national and global agendas.
Equally important is the need for communicators to adopt a more systems-oriented approach. This means connecting the dots between geopolitical decisions and health outcomes, helping stakeholders understand that these are deeply interconnected challenges. Investing in health is not just a moral imperative; it is an economic and strategic one. Strong health systems contribute to productivity, stability, and resilience. They are foundational to national security in the broadest sense.
Governments, multilateral organizations, private sector players, and civil society must come together to reassert the importance of health in the global agenda. Innovative financing mechanisms, public-private partnerships, and more efficient use of resources can help bridge funding gaps. But without political will, these solutions will remain insufficient.
If current trajectories persist, the consequences will extend far beyond strained health systems, they will reshape how societies absorb risk, respond to crises, and sustain economic stability. Healthcare cannot remain the residual line item in a world that is becoming more volatile, more interconnected, and more vulnerable. Narratives shape priorities, and priorities shape funding. If health continues to be framed as a cost rather than a cornerstone of resilience, it will keep losing ground to more immediate, visible threats. That framing must change urgently and decisively. Over the next decade, the countries that succeed in protecting population health will not necessarily be those spending the most on healthcare, but those most effectively integrating health into national security thinking. The real question before policymakers and global leaders is whether nations can remain economically stable, politically resilient, or socially secure while treating health as a
