Isaac Kfir notes that terrorism is usually defined as the real or threatened use of violence by non-state actors against non-combatants or civilians to achieve political, religious or ideological objectives. However, he argues that to be effective, counterterrorism efforts must also recognize other key features of terrorism. These include that 1) terrorist groups seek to justify their actions by presenting them as responses to state oppression; and 2) terrorist attacks are a form of communication. So how should counterterrorism programs account for these features? Here are eight points Kfir believes policymakers should consider.
