Divided Not Conquered

Terrorist, rebel, and insurgent groups are highly unstable. Amid fears of defeat and even death, intense disagreements have torn many organizations apart, from Syria to Iraq, Ireland to Spain. And while some of these divisions have preceded a group's decline and eventual defeat, others have launched some of the most notorious and deadly organizations in recent history. In Divided Not Conquered, Evan Perkoski analyzes how armed groups fracture and how breakaway splinter groups behave. Perkoski takes an unprecedented look inside these organizations to understand the specific disagreements that cause groups to break apart, like those over ideology, leadership, and strategy. Including case studies of republican militants in Northern Ireland, Basque militants in Spain, and the Islamic State in Syria and Iraq, Divided Not Conquered demystifies a complex yet common phenomenon with ramifications for counterinsurgency, counterterrorism, and our understanding of increasingly fragmented conflicts around the globe.
