Social work war and peace studies encompass a wide range of perspectives to reflect on the totalizing event of any war and consider diverse and multifaceted perspectives including gender, disability, age, decoloniality, anti-racist social work frameworks, trauma-informed work, and community mobilization. Exploring contexts and histories is essential if the discipline of social work is to be effective for people who need help during and after war. While some internationally renowned social work pioneers explicitly advocated and fought against the First and Second World Wars, there are currently only a few examples of transnational solidarity in times of war. Women in Black and Transnational Solidarity and Support with Social Work Educators from Ukraine Network stand out as exceptional cases. Social work educators and scholars sometimes find it difficult to move away from war-mongering ideologies, nationalisms, and the regimentation of women, men, and nonbinary people along traditional gender lines, instead of practising the principle of self-determination even in exceptional times. Some social work scholars and educators even refer to war rapists as “fathers”, reducing paternity to a genetic transfer of cells and thus minimizing the crime of war rape. The positioning of social work for peace should not be taken for granted and is not easy to achieve. One of the steps is therefore to engage in the international discussion on Principle 9.3 of the Global Statement of Social Work Ethics and in discussions on how social work can teach war and peace studies and what the challenges are.
