“Now I am become Death, the destroyer of worlds”
- The Bhagavad Gita
The world has recently endured COVID-19, followed by the Russian invasion of Ukraine, the worldwide outrage about unprovoked invasions and subsequent deaths of civilians, and, currently, the deadly war between Israel and Hamas in Gaza appears to have no end in sight. In the context of a long duration of bad blood between Palestinians and Israelis, Hamas attacked Israel in early October, an invasion which was evidenced by videos of murder, rape, torture, and kidnapping of civilian hostages. At the time of writing, while Hamas continues its rocket attacks on Israeli cities, Israel has responded with a ground invasion and massive bomb strikes, activities that have resulted in incremental deaths among civilians, a particular heart-wrenching tragedy in Gaza, with its very high population ratio of children and youth. The massive death and destruction have raised alarms among all nations. What is badly needed is humanitarian assistance in Gaza, where the population lacks food, water, and fuel. Israel, in the meanwhile, has lost the hostages in Gaza but also many of its young men and young women who are now waging war on five fronts.
Fear reigns on both sides. More civilians are being killed every day, injured, displaced, bereaved, traumatized, and deprived of home and livelihood. Fear of the outbreak of a regional conflict has spread beyond Gaza and Israel, and large-scale public demonstrations are taking place around the world, especially on Western university campuses where Palestinians are viewed as the underdogs in an unequal war.
We, as scientists and clinicians, have the means, whenever possible, of relieving anxiety and emotional distress. Hence, we feel the need to make our voices heard in the midst of this crisis. There are turning points in history that require the dissemination of good sense.
Armed conflicts significantly undermine the economic vitality of conflict-affected nations (Seleznova et al., 2023) and severely harm their social, physical, and human capital, both during and after the conflict is over. If international organizations are not given the opportunity and support to take urgent action, a humanitarian disaster will take place in Gaza. Amidst overwhelming despair and a general feeling of helplessness, we want to use our experience in researching the consequences of war and violence on mental health to lay out the facts regarding the impact of war on civilization.
The effects of violence, from Israel and Gaza to Afghanistan, Cambodia, the Democratic Republic of Congo, Iraq, Libya, Syria, Yemen, Myanmar, Nepal, Rwanda, Sri Lanka, Syria, South Sudan, Sudan, and Ukraine, have all been well studied (Familiar et al., 2021; Kienzler & Sapkota, 2020; Razjouyan et al., 2022; Sá et al., 2022). History has supplied unambiguous evidence of the lasting harm of warfare (Hyseni Duraku et al., 2023; Leshem et al., 2023; Saw et al., 2023; Thomas et al., 2023). International wars, civil wars, proxy battles, conflicts, invasions, and insurgencies all end badly. They are all accompanied and followed by disruptions in the delivery of basic social services, especially access to healthcare, which has led to epidemics and spikes in infection and diseases, critical battle-related injuries, and chronic disability (Blais et al., 2023), acute malnutrition, acute and chronic mental health conditions, and horrific deaths (Sher, 2023). Wars always result in widespread suffering, enduring stress, trauma, loss, and population displacement, which can reverberate and scar the well-being of future generations. This, in turn, leads to the continuation of violence across generations (Betancourt, 2015; Castro-Vale et al., 2019; Dashorst et al., 2019). In longstanding conflicts, past injustices are used as rationales for future retribution and aggression. Human beings tend to ruminate over past grievances and, thus, view retaliation as justified. Continued violence rips at the social fabric of society, and healing is difficult, but can be achieved (Kapshuk & Deitch, 2023). It was achieved, against all odds, in Northern Ireland (Uluğ et al., 2023).
Living in war-torn countries has been associated with physical handicaps, and mental and psychological anguish (due to exposure to death). Complaints such as post-traumatic stress disorder (PTSD), anxiety, depression, sleeplessness, nightmares (Birhan et al., 2023; Pavlova et al., 2023; Rogowska & Pavlova, 2023), alcohol and substance abuse (Dissanayake et al., 2023), suicidal thoughts, tendencies, and attempted suicides (Blais et al., 2023; Sher, 2023) sexual and non-sexual violence (Hladik et al., 2023), and psychosomatic disorders all have been reported. These will have long-lasting effects on affected individuals. Both aggressors and victims face immense mental challenges: war trauma, violations of human rights, social exclusion, discrimination, spiralling rates of family violence, poverty, and loss of social support.
Women and children are disproportionately impacted because they are unable to flee from danger due to their socioeconomic dependence on men (Bendavid et al., 2021). Parental loss and family disruption negatively affect children throughout their adult lives, partly because the memory of the terrors of war impairs the parenting abilities of survivors (Ugurlu et al., 2016). Children grow up with attachment difficulties and personality problems and remain, throughout life, at high risk of suicide. Soldiers who serve in combat are increasingly reported as suffering from the often-catastrophic effects of injuries, medical problems such as chronic pulmonary disorders, as well as post-traumatic stress (Jordans et al., 2009).
Decades of rehabilitation and rebuilding work are always required to aid in the recovery of individuals impacted by war as well as in the restoration of communities and the rebuilding of means of subsistence. Many losses, not only of life but also of cultural traditions and meaningful religious symbols and structures, are irreversible. When examining the effects of war on mental health and well-being, the results are invariably catastrophic whether for winners or losers, combatants or civilians.
One of the most visible impacts of living in war-torn countries has been physical disability. Wars disrupt the supply chain of food and potable water, contributing to malnutrition, gastrointestinal and respiratory problems, as well as an increase in community infectious diseases. Wars disrupt youth development and education (Gómez-Restrepo et al., 2023), leaving lasting transgenerational impacts on individuals and society. A notable concern is the mental health of first, second, and third generations of survivors.
Refugees are highly susceptible to trauma. As noted by the United Nations High Commissioner for Refugees (UNHCR), the main reasons for fleeing one’s country are related to war, the threat to survival, and the violation of human rights. These situations undermine mental health. Fleeing brings with it the need to embrace a survival journey that involves abandoning one’s identity and self-worth, leaving one’s family and friends, subjecting oneself to dangerous, illegal crossings, and often needing to rely on unreliable human smugglers. Parental loss and family disruption adversely affect migrants for life (Raturi & Cebotari, 2023). The inhumane conditions in which people seeking asylum are forced to live while awaiting international protection are disastrous for mental health. We know that human beings are resilient (Purgato et al., 2020) but eventually, a limit to resilience is reached.
In the present world situation, we need to prepare for the worst. Specific physical, psychological, and mental health promotional help will be needed. Psycho-educational, psychological, and other integrated health services will be required, as suggested by the recently released World Mental Health Report (World Health Organization, Noncommunicable Diseases and Mental Health Cluster, 2005). Actions are needed to scale up interventions that are effective and sustainable in promoting mental health and preventing the development of mental disorders (Tol et al., 2023). As proposed by WHO, in civil societies, basic training in mental health and mental health first aid for people in civil societies should be a concern of all governments. Thousands of persons will be displaced and dispersed in host countries (Teixeira-Santos et al., 2023). There will be resource constraints and cost escalations. All sides in a conflict must make concessions, and this is difficult when there are wide differences in social, religious, and cultural norms, traditions, and values. A large influx of internally displaced people fleeing from violence at home is increasingly putting strains on the healthcare systems, other social services, and economies of countries that welcome refugees (Somasundaram et al., 2023). There are compromises that civilians, host governments, and communities need to make so that refugees can integrate into the host society and contribute to their new country’s economic growth. If such an agenda fails, it will put pressure on the existing fabric of our global system and this usually leads to political unrest down the road.
Disinformation campaigns spread misinformation, disinformation, mal-information, tendentious information, and alternative facts on both sides of a war conflict. As a result, even the well-intentioned fall prey to incorrect certainties, which they convey through their social networks. This results in unnecessary polarization and pitches neighbour against neighbour, destroying social networks that would be needed to re-establish the backbone of societies. The authors of this paper, as scientists and medical professionals, believe that our efforts are best focused on (i) averting conflicts among ourselves as a global community of scholars, scientists, and practitioners (not an easy feat); (ii) analyzing the effects of war; (iii) assisting in the creation of relief efforts, (iv) developing and studying the beneficial effects of new mental health promotion and prevention strategies; and (v) planning for mental health resources for now and for the (ideally quick) return of peace.
This special editorial has briefly highlighted some of the ramifications of war. When a conflict occurs in any part of the world, it triggers ripple effects that render us all vulnerable to fear. To combat fear, we unite as scientists to voice our opposition to war in general, as contrasted to protesting the rightness of one cause versus another.
As scientists, we strongly encourage international leadership and diplomacy among statesmen as a path to enduring peace (Pandi-Perumal et al., 2022). Scientific evidence has the power to improve the world's health, equality, justice, resilience, and prosperity for all. Negotiations and compromise among partners in dialogue lead to far better outcomes than mutual killings. International helping organizations and impartial, well-respected international leaders are crucial agents in advancing peace initiatives and giving civilians in war-torn regions, refugees, and internally displaced persons the much-needed assistance they require. As Nelson Mandela pointed out:
“Negotiation and discussion are the greatest weapons we have for promoting peace and development.”
The United Nations (UN) is the driving force behind the Sustainable Development Goals (“Addressing Sustainable Development through Economic Empowerment,” 2019); this is an intergovernmental set of objectives that advocates for 17 goals and 169 targets, covering a wide range of sustainable development issues and measured through 230 individual indicators that are inextricably linked to peace and stability (United Nations, n.d.). The SDGs are imperiled by conflicts that derail the process and prevent the aspiration of achieving critical milestones; this affects not only the countries directly involved in the conflict, but all nations.
Peace means better quality of life and better mental health. There is abundant scientific evidence that vulnerable populations, the public, planetary health and safety, global security, and the global economy must be protected in these very dangerous times. As scientists, we are mindful of the challenging, intricate, multifaceted, and malignant consequences of wars. Apart from its impact on human health, it also hurts biodiversity, accelerates climate disasters, and intensifies social inequalities, inequities, and injustices. Let’s form a multi-stakeholder partnership involving scientists, policymakers, legislators, and regulators to facilitate a sustainable future for our planet Earth.
