Episode notes
Civil Wars Are The Central Global Security Problem
- Civil wars are the majority of armed conflicts and cause most fatalities globally.
- Thorsten Gromes notes about 60 conflicts in 2024 with roughly half being intrastate, making recurrence a central peace research problem.
Victory Versus Compromise Frames Postwar Outcomes
- Two dominant views dispute whether stable peace follows military victory or negotiated settlements with compromise.
- Gromes frames the debate and lists post-war choices: external involvement, democratization, dealing with the past, and power-sharing trade-offs.
Convergence Of Political Compromise And Military Power
- Gromes proposes peace endures when political compromise matches military power distribution.
- He tests the hypothesis that divergence between political benefits and military strength predicts recurrence.
