Murphy begins from a distinction that structures the entire argument. Some harms from American non-involvement are immediate and measurable, while others unfold over decades and may prove surprisingly modest in the long run. Averting the worst consequences of the climate crisis and preparing for the next pandemic fall squarely into the first category, where the absence of the United States government from global problem solving can have significant consequences. The United States remains one of the largest historical emitters of greenhouse gases and one of the most consequential funders of public health infrastructure, so its disengagement from these domains removes both material capacity and political weight from systems that depend on broad coordination. In these arenas, timing matters: delays in emissions reductions compound physically, and pandemic preparedness is only as strong as the weakest surveillance and response capacity in the chain.

The evidence for immediate, quantifiable harm comes in part from modelling studies published in the medical literature, which Murphy draws on to ground his argument. A mathematical modelling study of seven countries in sub-Saharan Africa, published in EClinicalMedicine, examined the impact of the freeze in funding for PEPFAR, the President’s Emergency Plan for AIDS Relief, and projected increases in HIV deaths and infections as a direct result. A separate retrospective evaluation and forecasting analysis published in The Lancet assessed two decades of USAID interventions and projected the effects of defunding on mortality up to 2030, finding that the programs slated for cuts had been associated with millions of averted deaths. These are not abstract governance questions. They are estimates of human lives, calculated with the standard tools of epidemiological modelling, and they illustrate precisely what Murphy means by dire immediate consequences even where the long-run architecture of global problem solving may endure.

Climate policy presents a parallel case with its own technical texture. Murphy cites the Rhodium Group’s Taking Stock 2025 analysis of United States energy and climate trends, which tracks how federal policy shifts alter the emissions trajectory of the world’s second-largest current emitter. When the American federal government relaxes domestic climate policy and steps back from international climate finance, the global emissions budget, a finite quantity of carbon that can be released before warming thresholds are crossed, absorbs the difference. Unlike some areas of governance, climate physics offers no institutional workaround: the atmosphere integrates emissions from all sources regardless of who is in office. This is why Murphy classifies climate among the domains where American non-involvement may have significant consequences rather than merely symbolic ones, and why parallel scholarship in the same journal examines whether global climate governance nonetheless remains resilient under the current administration.

Yet the article’s most counterintuitive claim concerns the domains where American withdrawal matters less than headlines suggest. Murphy argues that the long-run impact on global problem solving may be small in certain cases, even when immediate consequences are dire, and he offers economic inequality across countries as a likely example. Drawing on Branko Milanovic’s analysis of the three eras of global inequality from 1820 to 2020, Murphy situates present turbulence within long structural trends. The convergence of incomes between countries that defined the past three decades has been driven principally by economic growth in Asia, particularly China and India, rather than by American policy choices. A US government that turns inward may slow or complicate specific redistributive mechanisms, but it neither creates nor controls the deep forces reshaping the global income distribution. The immediate harms of cuts to development assistance are real, as the Lancet modelling demonstrates, but the underlying trajectory of between-country inequality is shaped by forces far larger than any single administration.

This leads to the article’s deeper historical claim, and the one Murphy identifies as the most important lesson for practitioners. Even if the US government becomes unimportant or an impediment to solving global and planetary problems for many years, the basic politics of their solution is likely to remain similar to what it has been since the mid-nineteenth century. Global governance, in Murphy’s telling, was never primarily the creature of great-power governments. From the international public unions of the 1800s through the technical standard-setting bodies documented in his earlier work on engineering rules since 1880, the machinery of global problem solving has been built and maintained by international epistemic communities, networks of scientists and experts, social movements, and civil servants at every level. Susan Strange’s famous critique of the Westfailure system, and the scholarship on non-hegemonic regimes collected under the title Cooperating Without America, both support the proposition that cooperation among other actors can proceed even when the hegemon abstains.

The historical record Murphy invokes is richer than the current moment might suggest. His references span the scholarship on how governments have repeatedly lost control over the proliferating structures of global governance, the role of emerging powers in disrupting and reshaping the World Trade Organization, and the work of what Thomas Weiss and colleagues have called the Third United Nations, the civil society organizations and advocacy networks that operate alongside and often in tension with member states. Recent historical scholarship on Pan-Africanism, including Howard French’s account of Kwame Nkrumah and the high tide of global Black solidarity, reminds readers that transformative global projects have often been driven by movements with no great-power sponsorship at all. Linda Gordon’s study of seven social movements that changed America makes the complementary domestic point: American politics itself has repeatedly been redirected from below rather than from the White House.

What does this mean concretely for the scientists, officials, and advocates now confronting an American government hostile to their work? Murphy’s answer, though framed in careful academic language, is essentially a call for persistence grounded in structural analysis. Members of international epistemic communities, social movements, and civil servants at all levels should remember that their work in global problem solving has always been just as important as that of the elected or self-appointed governments of even the most powerful countries. The technical standard-setters who keep the internet, aviation, and global trade interoperable do not require American federal participation to continue meeting. The epidemiologists who maintain disease surveillance networks, the climate scientists whose models inform every national assessment, and the statisticians who track global inequality all operate within institutions whose legitimacy and funding derive from far broader coalitions than Washington’s current disposition.

Murphy is careful not to minimize the danger. The article acknowledges commentary, including Paul Krugman’s argument that Trump is a symptom rather than the cause of declining American democracy, and it engages with assessments of how much damage a determined administration can inflict on institutions at home and abroad. The modelling studies on PEPFAR and USAID stand as evidence that the immediate human costs of withdrawal are severe and quantifiable. A widely discussed recent book on the collapse of large-scale societies, reviewed under the grim headline of a one-in-three chance of apocalypse, reflects the mood of existential concern that Murphy’s measured prose deliberately works against. His point is not that the situation is benign, but that despair is analytically unwarranted: the system of global problem solving has survived hostile hegemons, world wars, and the withdrawal of major powers before, and its resilience resides in actors that no single election can dismantle.

The article thus closes the loop between diagnosis and prescription. The differentiation of harms is the analytical core: climate and pandemic preparedness suffer significantly from American absence, inequality between countries follows its own long trajectory, and the politics of global problem solving remains fundamentally continuous with its nineteenth-century origins. For a readership of researchers and practitioners, the practical implication is to direct scarce attention toward the domains where American withdrawal does structural damage, while refusing the temptation to treat every global institution as hostage to Washington. The lesson Murphy draws from nearly two centuries of global governance is that the work has never depended on the goodwill of the powerful alone, and that the experts, movements, and public servants who built it retain, even now, the capacity to keep building.

The scale of the retrenchment is staggering. The United States Agency for International Development, historically the largest single donor in global health, has slashed its contributions by more than 80 percent in 2025, according to the commentary, which draws on recent evidence including a retrospective impact evaluation and forecasting analysis published in The Lancet. Similar contractions have followed from the United Kingdom, France, and other Western donors, producing a synchronized withdrawal that no single national health system was designed to absorb. The Lancet analysis estimated that USAID funding alone has prevented nearly 92 million deaths over the past two decades, and it projects that sustained funding reductions could contribute to substantial excess mortality by 2030, with the steepest losses anticipated among children under five, people living with HIV/AIDS, tuberculosis patients, and mothers. If those projections hold, the cuts threaten to reverse hard-won movement toward the Sustainable Development Goals in a single budget cycle.

Nutrition is emerging as one of the most immediate fault lines. Approximately 149 million children worldwide are affected by stunting, a condition that permanently compromises physical growth and cognitive development, and continued reductions in humanitarian financing are placing additional pressure on the community-based nutrition programs that hold this figure in check. The commentary highlights the situation in Bangladesh’s Rohingya refugee camps in Ukhiya and Teknaf, where research on declining humanitarian funding and health security shows that acute malnutrition now exceeds emergency thresholds as water, sanitation, and healthcare services deteriorate in parallel. When food rations shrink, clean water becomes scarcer, and clinics close, the effects compound: malnourished children are more susceptible to infectious disease, outbreaks spread more readily in unsanitary conditions, and weakened health systems lose the capacity to respond. The authors describe this as a cascading pathway in which funding contractions reduce operational capacity, disrupt service delivery, and ultimately worsen health outcomes while increasing social and economic vulnerability.

Sexual and reproductive health services are deteriorating along a parallel track. Official development assistance for these services has dropped by 27 percent, a decline that researchers writing in Conflict and Health warn threatens maternal survival in conflict zones, where pregnancy-related complications are already among the leading causes of death for women of reproductive age. The commentary notes a striking policy gap: only 40 percent of countries at risk have integrated essential sexual and reproductive health services into their emergency preparedness frameworks. This means that when funding disappears or a crisis escalates, there is often no institutional scaffolding to maintain even the most basic interventions, such as the Minimum Initial Service Package designed to prevent excess maternal and newborn morbidity and mortality in humanitarian emergencies. Mental health support, meanwhile, remains chronically underfunded despite rising needs, a persistent shortfall documented in research priorities published in The Lancet Global Health that predates the current funding crisis and has now been sharply aggravated by it.

The authors are careful to situate the crisis within a more nuanced debate about aid itself. Humanitarian assistance, they acknowledge, has long been criticized on grounds of effectiveness, dependency, donor accountability, and sustainability, and excessive reliance on external financing can weaken incentives for domestic investment and produce fragmented service delivery when transition strategies are absent. Yet they draw a crucial distinction between gradual, well-planned transitions and abrupt withdrawal. Sudden funding cuts, implemented without phased adaptation mechanisms, risk undermining health gains before national systems develop sufficient capacity to absorb these responsibilities. Evidence reviewed in the commentary suggests that abrupt aid reductions are unlikely to promote immediate self-reliance; instead, they increase the risk of service disruption precisely at the moment local systems are least equipped to compensate. National governments in affected countries generally lack the fiscal space or infrastructure to absorb such shocks rapidly, while multilateral agencies face budget constraints of their own, leaving a gap that no existing actor can currently fill.

Beyond the clinic and the feeding center, the commentary frames aid reductions through a broader social and political lens. Funding contractions are shaped by shifting geopolitical priorities, domestic fiscal pressures within donor countries, governance challenges, and changing global development agendas, and their consequences radiate outward from health systems into weakened institutional trust, reduced social protection, economic insecurity, displacement pressures, and widening inequality. In fragile and conflict-affected settings, these interacting forces can further erode system resilience and complicate long-term recovery, creating feedback loops in which deteriorating conditions generate new emergencies that demand even more resources. The authors argue that humanitarian aid is not charity but a cornerstone of global public health security, and that its withdrawal may create ripple effects that destabilize fragile states, contribute to migration pressures, undermine pandemic preparedness, and corrode trust in international cooperation itself. In an era when pathogens cross borders within hours, a weakened surveillance and response capacity in one region is a vulnerability for every other.

To avert the worst outcomes, the commentary lays out a prioritization strategy grounded in maximizing the impact of whatever resources remain. Existing funding, the authors argue, should first protect essential and high-impact services: child nutrition, routine immunization, maternal and newborn care, infectious disease programs including HIV and tuberculosis, outbreak preparedness and response, water, sanitation, and hygiene, and mental health services. In contexts of severe resource constraint, lower-priority activities and duplicative delivery structures may require temporary consolidation to preserve these core interventions. The authors also call for anchoring essential reproductive health services into national disaster frameworks, establishing dedicated emergency funds, mandating frontline provider training, and integrating preparedness into broader health system strengthening, so that the next funding shock does not again find critical services without institutional protection.

Localization emerges as a central recommendation, but one the authors treat with technical realism rather than slogan-making. Evidence from a scoping review published in BMJ Global Health suggests that locally led responses can improve contextual adaptation, operational continuity, and community trust, yet implementation remains constrained by administrative barriers, unequal funding access, and limited institutional capacity. The commentary proposes practical mechanisms to close this gap: simplified grant mechanisms, technical support, flexible procurement arrangements, and stronger inclusion of local organizations in planning and decision-making processes. Alongside localization, the authors urge prioritizing multilateral coordination through institutions such as the World Health Organization, UNICEF, and Gavi, whose operational agility matters most where bilateral aid has become volatile, and promoting innovative financing mechanisms, including pooled funds and public-private partnerships, to bridge the gaps left by traditional donors. Investment in robust surveillance, data systems, and research on intervention effectiveness is presented as the backbone of transparent resource allocation during scarcity.

The commentary’s conclusion is a warning and a roadmap at once. Continued reductions in humanitarian financing, the authors write, will place substantial pressure on public health systems globally and demand coordinated responses to protect essential services and maintain recent health gains. Urgent action grounded in evidence, strategic prioritization, sustainable financing, and stronger local capacity is needed to minimize avoidable losses. For low-resource settings already grappling with conflict or climate shocks, the window for a managed transition is narrowing. Long-term resilience, the authors argue, will ultimately depend on adaptive financing mechanisms, effective monitoring, stronger governance, and coordinated action across the humanitarian and health sectors, but getting there requires external support sustained long enough for domestic systems to stand on their own. The alternative, the evidence suggests, is a generation of preventable deaths in the very places least able to bear them.
