While proxy war is characterized by two or more actors aimed at a common purpose, the relationship between the two actors is hierarchical, and the main actor is involved in conflicts through another actor (principal-agent relationship) in order to avoid costly and bloody wars and to achieve his political purpose. It is usually the intelligence organizations of the principal actor that ensure the principal-agent relationship between actors in proxy wars. Intelligence agencies are responsible for coordinating all stages, including organizing, training, arming and conducting operational activities of agent actors. These duties of intelligence organizations in proxy wars make them “quarterbacks”, but besides that, intelligence organizations are basically based on “reasonable deniability”, because of that it makes the proxy wars discussed at the point of violation of sovereignty even more controversial. This study will examine the activities of intelligence organizations that make them quarterbacks and controversial in proxy wars and relationship between intelligence organizations and agent actors will be analyzed in depth. For this purpose, case study was conducted in the study, which is one of the qualitative research designs. For in-depth analysis, the Quds Force and its activities in Lebanon, Iraq, Syria and Yemen have been selected as cases.
