Conclusion
The volume's concluding chapter recaps major themes & issues arising from the question of whether major war is in decline. A chief conclusion from the contributions is that institutional & normative shifts matter. The process by which international law & norms have been institutionalized has altered international relations, perhaps permanently. It is obvious that international institutions & norms are not yet sufficiently potent to present an absolute deterrent to major war; it is just as obvious that the institutions of collective security & international law are not fail-safe. Yet international institutions have garnered new significance by establishing new normative standards & media for negotiation & communication. K. Coddon
