The past two decade has witnessed a nuanced approach to addressing the institutional and normative responses to Africa’s unending security challenges, particularly the African Union’s mandate to create the African Standby Force (ASF). The growing infeasibility of operationalising the ASF has thus stimulated the conception of the South African initiated African Capacity for Immediate Response to Crises (ACIRC). This article places the establishment of ACIRC within the theoretical concept of flexible integration, specifically the ‘multiple-speed’ approach. This approach highlights the willingness of a group of member states to proceed with integrative measures at a much faster and deeper pace. The possibility of developing an AU framework that sets the operational parameters of this idea is at the core of this article.
