The article examines the synergistic effect of strengthening the state's defense capability, its military power, and improving the effectiveness of social policy and the level of social security of the country's citizens. Using multi-criteria analysis of integral indices such as the Security Threat Index, the Refugee and Displaced Persons Index, and the Comprehensive National Power Index, the study traces the impact of war on the social component, the development of social security, the institutionalization of social protection systems, and the creation of ministries of national welfare to overcome socio-economic consequences of war. The Ukrainian model of state functioning in wartime is identified as a symbiosis of effective social protection policy and strengthening the country's military power through systematic support of the army: "strong home front – strong army." War significantly transforms the policy of social protection and social security, causing the need for state intervention to support citizens during and after military conflicts. In such circumstances, governments are forced to intervene in socio-economic relations to ensure the survival and well-being of their citizens. This intervention takes the form of social welfare in the form of benefits and subsidies, free education and healthcare for the poor, as there is a high probability of losing their jobs, homes, or even lives. The article also discusses the global socio-economic system's adaptation to the turbulent environment of the BANI and TUNA worlds, where new types of risks are difficult to control and their consequences are impossible to predict. Russia's large-scale war against sovereign Ukraine has revealed the instability of the world order and convincingly proves the need to develop a Ukrainian model of a "welfare state in war" with an emphasis on strengthening the military component. The article highlights the importance of political consolidation of citizens around common values and interests, preservation of civil peace, overcoming existing political contradictions, and achieving a socially acceptable standard of living. This is possible if the balance of interests of all objects of national security protection is maintained. The study also reviews the experiences of other countries in developing social protection systems during and after wars, emphasizing the role of institutionalization and the creation of ministries of national welfare. The article concludes that a "reanimation package of reforms" is necessary to create a reliable home front for the Ukrainian army, reduce social tension, lay the foundation for active social policy, and strengthen social security in wartime and post-war recovery. The article also discusses the importance of social welfare in ensuring the military strength of the country and the need for a new social strategy for Ukraine.The article examines the synergistic effect of strengthening the state's defense capability, its military power, and improving the effectiveness of social policy and the level of social security of the country's citizens.
