Abstract
This article examines the potential of the Shanghai Cooperation Organization (SCO) to function as an alternative to Western military-political blocs and provides a comparative analysis with the North Atlantic Treaty Organization (NATO). The study is conducted within the broader context of the transformation of the global order, the rise of multipolarity, and the diversification of regional security architectures. It compares NATO as a highly institutionalized military alliance based on legally binding collective defense commitments with the SCO as a coordination-based security platform grounded in the principles of sovereignty, consensus, and non-interference.The analysis covers the degree of military institutionalization, strategic orientation, enlargement policies, and normative foundations of both organizations. It is argued that the absence of a binding collective defense clause within the SCO framework limits its transformation into a traditional military alliance; however, this structural flexibility allows member states to preserve strategic autonomy and avoid rigid bloc confrontation.The findings suggest that the SCO should not be viewed as a direct structural analogue of NATO but rather as an alternative regional security model that reflects the dynamics of the emerging multipolar world order and the evolving geopolitical landscape of Eurasia.
