To avoid that, the rules of engagement must be conscious of collateral damage and work to minimize it. Another researcher, Audrey Cronin, lists six primary ways that terrorist groups end:
Capture or killing of a groups leader. (Decapitation). Entry of the group into a legitimate political process. (Negotiation). Achievement of group aims. (Success). Group implosion or loss of public support. (Failure). Defeat and elimination through brute force. (Repression). Transition from terrorism into other forms of violence. (Reorientation). Databases
