Since the establishment of NATO, numerous studies have been conducted in analyzing ways to bolster security for the trans-Atlantic community. As a significant and indispensable ally, Türkiye possesses substantial military capabilities and continues to contribute decisively to the Alliance's collective-security framework. The transforming identity of Türkiye as an ardent actor in the international community re-configured the strategic nature of the country in its zealousness to pursue peace, security, and stability in its 360-degree geographic vicinity. This study focuses particularly on breaking down the worldview harbored by Muslim realists in exercising the free will to choose a trajectory of peace and security perspective couched in a faith-based rational approach. The concept of muessir/efficacious power, in this scope, sheds light on the new identity of a vibrant nation-state on the verge of maximizing its military role during regional and global anxieties. On the horizon of uncertainties and challenges, the faith-based thought process of a Muslim realist serves as an intellectual mind map in setting the framework for the means for peace-based solutions, bringing the conversation back to ethics of war, reifying values intrinsic to all humans and promoting peaceful conduct in contributing toward the formation of a renewed regional and global security architecture.
