An advantage of this unconditional surrender or complete destruction policy, permitted by an overwhelming military advantage over their opponents without fear of a realistic strategically vital retaliation, is deterrence to like-minded groups and the shrinking of potential terrorist recruits to the most hardcore in the world. This depletion of human resources from the jihadist side when under serious pressure may be further reinforced by the common knowledge that the allied Western nations in this war usually do not abuse prisoners of war, or are far less likely to do so than local regimes. Despite this, some tactical agreements have been made with groups of such forces in the midst of battles, like in the battle of Raqqa (2017).
