Conclusion: Northern Ireland and International Relations theory
The concluding chapter summarizes the major points of the chapters and identify some common themes that emerge from the analysis provided by the contributors. This chapter explains how International Relations theory is furthered by the attempt to apply the case study method to explore the causal mechanisms associated with different theories. While the Northern Ireland case confounds the theoretical predictions of multi-lateral governance and the literature on decommissioning, certain theoretical approaches, especially those emanating from constructivism, proved useful in explaining the arrival of a peace settlement in Northern Ireland. Constructivism has the advantage of allowing the researcher to focus on the unique characteristics of the actors involved and the ideas and ideologies they devised and employed to pursue their interests, including peace.
