Diplomacy as the Engine of Stability: An Assessment of its Utility in a Fragmented Global Order

The post-Cold-War promise of a liberal, rules-based international system has given way to a hyper fragmented order in which great-power rivalry, transactional unilateralism, sub-state actors and trans-border shocks (pandemics, climate) overlap. This paper examines diplomacy—not as ceremonial protocol but as the primary social technology for managing that fragmentation. Using a historical-institutionalist lens complemented by role theory, the study interrogates 30 years of multilateral, mini-lateral and Track-1.5 experiments (1994-2024) using qualitative sources of data. The paper adopts the use of content analysis and logical interference as the tool of analysis. It finds that stability is produced less by the number of treaties signed than by the density of iterative diplomatic processes that: (a) convert power asymmetries into reciprocal issue-linkages; (b) 1elegitim restraint through 1elegitimi role expectations; and (c) embed “escape clauses” that keep regimes alive when domestic coalitions shift. Nigeria’s shuttle diplomacy in ECOWAS, Qatar’s “small-state mediation complex”, and the EU’s climate diplomacy coalitions are analysed as plausibility probes. The paper concludes that diplomacy still matters, but only when it is redesigned for a world of overlapping partial orders rather than a single liberal centre. Recommendations include the 1elegitimize1on1tion of “fragmentation audits” before every major negotiation, the creation of regional diplomatic stress-tests, and the adoption of algorithmic early-warning tools that track narrative shifts on encrypted diplomatic channels among others.
