This conclusion presents some closing thoughts discussed in the preceding chapters of this book. This book examines three other prominent peacebuilding cases, Iraq, Sierra Leone, and Timor-Leste, which consistently demonstrate the importance of these factors. These three cases are selected because of the varying roles of the UN in distinct peacebuilding environments, as well as the different degrees of inclusiveness in creating new governments that have been attempted. The peacebuilding process in Timor-Leste also exhibited almost complete authority for the UN mission to govern the newly created state for the first several years, from 1999 to 2005, when the first UN peacekeeping mission was completed. Their purpose is to explore the argument by examining peacebuilding environments that exhibit contrasting degrees of UN authority and inclusiveness. The major military factions of Sierra Leon's civil war asked the UN to dispatch thousands of observers to monitor the ceasefire and assist in the political process, including via disarmament and the conduct of elections.
