Abstract
This article explores the status of a UN mandate for military intervention, especially in the aftermath of the non-mandated interventions in Kosovo and Iraq. It examines the realist and positivist approaches to this issue, and proposes a third approach, called the ?human rights model? in which public legitimacy plays a key role. It shows that not only political assessments but also legal ones differ on this question according the premises they are based on. The article further analyses how normative and military power interacts in today's global public debate, and concludes that legitimacy for an intervention is established on a case-by-case basis. The existence of a UN mandate no longer gives automatic legitimacy
