When we take a look back at the way Western states have fought terrorist organizations in the last 20 years, it is difficult not to think that these alternatives to war might have been more ethical than the decisions to invade Afghanistan and Iraq in 2001 and in 2003. These cases speak for themselves as they have both led to the death of hundreds of thousands of innocent civilians, which is highly paradoxical in light of the logic that supported these interventions. There is a need to think of alternatives to war that will imply the legitimization of proactive sets of measures that would allow states to effectively prevent terrorist attacks through the use of kinetic force in a limited extent as a way to avoid the terrible and unpredictable effects of wars. Violent Alternatives to War: Justifying Actions Against Contemporary Terrorism engages in a moral discussion of the challenges associated with violent alternatives to war when confronting terrorism and suggests a comprehensive approach to how this form of violence can be legitimized and how it ought to be used against this contemporary threat.
