No corner of the globe is exempt from the scourge of conflict. Every year, hundreds of thousands of civilians die as a consequence of armed conflict, and millions more are displaced. These conflicts are brutal, durable, and global. Oftentimes, they are characterized by genocide, as in Bosnia, Darfur, Iraq (ISIS), Myanmar, and Rwanda, or widespread atrocity crimes, as in the Central African Republic, the Democratic Republic of Congo, Libya, Syria, and Yemen. As is often said, it is easy to start an armed conflict, but excruciatingly difficult to end one. In any given year, there are nearly four dozen active armed conflicts around the globe. While some of these conflicts may transpire over a relatively short time (3–5 years), others remain active for a decade or more, and still others are “frozen” for decades on end, continuing to contribute to instability and insecurity.
