Book excerpt: America is at an important turning point. Remote warfare is not just a mainstay of post–9/11 wars, it is a harbinger of what lies ahead—a future of high-tech, artificial intelligence–enabled, and autonomous weapons systems that raise a host of new ethical questions. Most fundamentally, is remote warfare moral? And if so, why? Joseph O. Chapa, with unique credentials as Air Force officer, Predator pilot, and doctorate in moral philosophy, serves as our guide to understanding this future, able to engage in both the language of military operations and the language of moral philosophy. Through gripping accounts of remote pilots making life-and-death decisions and analysis of high-profile cases such as the killing of Iranian high government official General Qasem Soleimani, Chapa examines remote warfare within the context of the just war tradition, virtue, moral psychology, and moral responsibility. He develops the principles we should use to evaluate its morality, especially as pilots apply human judgment in morally complex combat situations. Moving on to the bigger picture, he examines how the morality of human decisions in remote war is situated within the broader moral context of US foreign policy and the future of warfare.
