The relevance of this article is due to the fact that the modern world-system has plunged into a state of extreme instability, the next era of global turbulence has already begun, which in historical retrospect led to the deployment of large-scale wars. Today, when the world-system once again stands on the threshold of the unfolding of crisis-militaristic phases of its cyclical development, taking into account the accumulated nuclear arsenal and, in general, the level of development of military technologies, it is necessary to resolve the aggravated inter-country and inter-civilizational contradictions peacefully in order to preserve the achieved level of civilizational development and to achieve the goals of sustainable development in the future.

The purpose of this article is to explore, in the context of military-economic cyclicality, the prospects for sustainable socio-economic development and to justify the need for comprehensive demilitarization.

Methods: we applied the institutional and cyclical conjuncture methodology, including the logical-historical and dialectical method, as well as general scientific methods of analysis and synthesis, induction and deduction.

The scientific novelty is contained in the following research results: the essence of military-economic cycles is determined, the role of their crisis-militaristic phases in the cyclical dynamics of the capitalist world-system is substantiated; shows the increasing militarization of the economy, the industrialization of war and the economic policies of military Keynesianism; it has been revealed that the cyclical nature of wars is clearly manifested in the deployment of such global cycles of capitalism as Kondratiev cycles, long cycles of world politics, cycles of hegemony; the need for demilitarization of the economy and public consciousness is substantiated to achieve the goals of sustainable socio-economic development.
