Notoriously, state-building is a key enterprise in regard of addressing the international conflicts throughout the globe. The consolidation of peace associated to it is intimately connected with the institutionalization of liberal ideas in structuring realms such as the political, the economical and the social spheres. Departing from Foucauldian concepts such as dispositif, government, discipline and biopolitics, this paper aims to critically analyze the post-conflict state-building practice. In a first moment, the paper delineates how peace was operationalized during the Cold War and post-Cold War periods. In a second moment, it will present the Foucauldian conceptual tools that enables the (re)problematization of the state-building practice as a post-conflict normalizing dispositif, rather than merely a conflict-resolution tool.
