| Summary/Abstract |
Several factors contribute to or inhibit the “contagiousness” of regional conflict and irregular warfare, whether conducted at the interstate, extrastate, or intrastate level. Five broad drivers of the diffusion of regional conflict are (1) weak states, (2) anticipated power shifts, regional and domestic, (3) unstable and poorly controlled border regions, (4) large refugee flows, and (5) the religiously-based non-state militant campaign against the state as an organizing principle of world politics. These factors are both endogenous and exogenous to particular states and societies, and must be considered alongside the standard factors considered in international relations literature to be the basis of “dangerous state dyads:” geographic contiguity, absence of alliances, absence of an advanced economy, absence of a democratic polity, and absence of a regionally preponderant power. Two case studies illustrate this argument: the rise of Islamic State, and the awareness of the causes of contagion in regional conflict implicit in Israeli security policy.
