The legitimacy of the military, private military and security companies, and just war theory

The legitimacy of the military is frequently overlooked in standard accounts of jus ad bellum. Accordingly, this paper considers how the military should be organized. It proposes a normative conception of legitimacy - the 'Moderate Instrumentalist Approach' - that outlines the qualities that a military should possess. It then assesses the three leading ways of organizing the military according to this approach: the use of private military and security companies (PMSCs), a conscripted force and the all-volunteer force (AVF). The paper argues that the AVF, despite some notable problems, is the most legitimate way of organizing the military. © The Author(s) 2011.
