This chapter concludes the book, which examines why Islamist civil wars are especially resistant to resolution and explores pathways toward their end. It draws out conclusions based on the quantitative analyses as well as the case studies of Afghanistan, Mauritania, Mali, and Syria, showing how conflicts framed in Islamist terms can become strategically embedded within transnational networks, increasing uncertainty about actors’ strength and resolve, thereby adding to their intractability. Importantly, Islamist civil wars are not inherently unresolvable; rather, their persistence stems from external entanglements. Insulating conflicts is key to their resolution. Endings of Islamist conflicts may come with setbacks for women’s rights and minority protections, underscoring the need for third parties to mitigate this. The chapter discusses how our book bridges the conflict resolution literature and strategic studies, emphasizing the role of transnational dynamics over ideology alone. It concludes with policy implications: prioritize localization and discourage external entanglement to create openings for conflict resolution in Islamist civil wars.
