“In the age of ISIS, can we still have ‘just wars’?” In her interview with Gary Gutting, Cecile Fabre argues that the principles underlying the “just war” tradition apply not only to “traditional” wars between nation states but also to war against ISIS. “It’s illusory to think that we can ever once and for all defeat terror — as illusory as to think that we can eliminate murder, rape, drug trafficking, and so on. As I noted earlier, human beings have always done those things to one another. Most of us don’t think that the best way to stop suspected murders, rapists, and traffickers is to bomb into the ground the areas where we think they are hiding. The most we can do is to catch and punish them (or if necessary kill them with minimum collateral damage). We do so knowing that we will not be able to spare all likely victims. Outside of war, the price we pay for abiding by moral principles is a great deal of wrongful suffering. The same is true regarding war.”
