IO survival politics: international organisations amid the crisis of multilateralism.

International organisations (IOs) have never been more authoritative and potentially agential while simultaneously faced more intense threats to their continued existence. Amid these dialectic conditions, this article identifies a novel type of behaviour: IO Survival Politics. IO Survival Politics occurs when senior institutional actors perceive the organisation to face an existential threat and, in response, employ extraordinary strategies to ensure the organisation's continued existence. Survival Politics thus differs both in degree and kind from the ways in which secretariats exercise influence during conditions of normal policymaking. Two case studies illustrate the concept: (1) the European Commission's response to Brexit and (2) NATO's response to President Trump's withdrawal threats. Drawing on 87 interviews with senior officials, the article shows that IO Survival Politics occurs across a range of diverse IOs in face of diverse threats and can be a crucial factor in determining the fate of IOs in crisis. By conceptualising IO Survival Politics, the article intends to open new avenues for research and advance scholarly understanding of IOs and the crisis of multilateralism. [ABSTRACT FROM AUTHOR]
