In the digital age, artificial intelligence (AI) has introduced unprecedented tools for manipulating information, notably through the creation of highly realistic fake images. This paper examines the growing role of AI-generated imagery in shaping public perception during armed conflicts. Through a qualitative analysis of five prominent case studies—spanning the Russia-Ukraine war, the Israel-Gaza conflict, the Syrian civil war, and a U.S.-based misinformation incident—the study investigates how synthetic visuals are employed to influence emotional reactions, manipulate political narratives, and disseminate strategic disinformation. The findings reveal five dominant manipulation tactics: emotional provocation, strategic distortion, moral framing, panic induction, and distraction from critical narratives. Drawing upon existing literature, the study situates visual disinformation within the broader context of hybrid warfare and psychological operations. The paper concludes that AI-generated fake images pose a serious threat to truth, public trust, and media ethics, especially in times of crisis. Recommendations for future research include developing cross-disciplinary strategies to detect, regulate, and educate against visual misinformation. The insights presented here contribute to ongoing debates in media studies, conflict communication, and AI governance.
