> Why does government violence deter political challengers in one context but inflame them in the next? This paper argues that repression increases opposition activity at low and moderate levels but decreases it in the extreme. There is a threshold level of violence, where the opposition becomes unable to recruit new members, and the rebellion unravels—even if the government kills more innocents. We find empirical support for this proposition in disaggregated data from Chechnya and a meta-analysis of sub-national conflict dynamics in 71 countries. The data suggest that a threshold exists, but the level of violence needed to reach it varies. Many governments, thankfully, are unable or unwilling to go that far. We explore conditions under which this threshold may be higher or lower and highlight a fundamental trade-off between reducing government violence and preserving civil liberties.
See El Salvador for another example of this.
