From Kosovo to Syria: the transformation of NATO Secretaries General's discourse on military humanitarian intervention

The civil war in Syria began approximately four years ago and has resulted in the murder of thousands by the Assad regime and the flight of millions to neighbouring countries. The international community's reluctance to intervene to halt the ongoing massive human rights violations has been explained in geopolitical, military-strategic, diplomatic, and legal terms. Yet, what does this imply normatively? And does the weakening of the military humanitarian intervention (MHI) norm support arguments regarding the poverty of constructivist security studies? This article examines these two questions and demonstrates the weakness of the MHI norm, especially in light of the new interpretations and meanings which authoritative agents ascribe to its key conceptual components in changing strategic, social and political contexts. Yet, the article employs constructivist tools to explore the endogenous challenges to the MHI norm while proving the added value of constructivist security research, not only for explaining "norm evolution" but also "norm decline". Taking discourse as a reflection of social norms and an arena for encouraging new intersubjective interpretations of concepts, it examines the above assertions by analysing the discourse of NATO Secretaries General from 1999 (Kosovo crisis) to today.
