In the convoluted history of Afghan politics, the Talibanization phenomenon reflects a complicated nexus of religious deontology and political ideology. The Taliban-brand deontology - their commitment as a moral obligation to waging war against all anti-Islamic forces - has been manifesting in terms of their strict adherence to the fundamentalist interpretation of Islam. They have been putting all their efforts into flourishing practices and norms in order to establish a religio-socio political order that they think they are divinely mandated for as the vicegerent of God on earth. This reflects their dedication to the religious-cum-deontological framework guiding their actions as obligatory pursuits as per their interpretation of Islam. The politico-ideological foundations of the Talibanization phenomenon is characterized by the accumulation of power as an instrument to validate their religious-deontological commitment. Now in the Afghan lifeworld, the deontology-ideology composite defines the Taliban dominion as a dynamic synthesis of the religious absolutism and the political expediency, whereby religious obligations strengthen political aspirations and political aspirations exploit religious principles. This argument intends to show the inherent complexities of human beliefs and politics in the nexus of both national and international affairs of Afghanistan through the recent history of the fusion of religious sentiments and political motivations of the Afghan population leading to a series of dynamic shifts and contemporary international political challenges. It argues to enlighten a perspective responding to the possible interpretation of national and international policies that the Taliban can religiously-cum-politically formulate at present.
