The global geopolitical order is seemingly in an evolutionary transition from a US-led Western-centric unipolar order (Global North) towards a multipolar and non-Western-centric configuration (Global South). Such an evolutionary change in how international relations are configured and practiced has implications, both theoretical and practical, in terms of how such concepts as security are conceived and operationalised. However, this evolution in thinking may lag behind the changes taking place in the political, physical, and informational environments. The calculus and balance of risks and threats, real and perceived, can and is changing. This commentary article takes critical stock of the academic arguments concerning contemporary thinking on the concept and practice of security in the twenty-first century.
