Cooperation and alliances between countries are formed mostly on the basis of common interests, interests and enemies. One of the important factors in the convergence between Saudi Arabia, the UAE and the Zionist regime is the confrontation with the influence and power of the Islamic Republic in the region. In fact, these collaborations have been formed to counter a common threat called Iran. One of the most important consequences of their convergence on the country's security environment is the provision of defense cooperation for destabilizing, terrorist and subversive actions by the Zionists. Therefore, the aim of the present study is to "identify and enumerate possible defense cooperation between the Zionist regime, Saudi Arabia and the UAE against the Islamic Republic of Iran." In terms of the type of research, this research is an application that has been done based on screenwriting. To achieve this goal, trends, actors, drivers and uncertainties affecting cooperation between them were studied. Based on the overlap of two key uncertainties, "US regional policy and military-security movements by regional and trans-regional actors," four scenarios were developed for possible cooperation between Saudi Arabia, the UAE, and the Zionist regime. These scenarios were evaluated from the point of view of experts and experts. Finally, scenario number three (West Asia region; relatively stable regions) is the most desirable scenario for the Islamic Republic of Iran and scenario number one (West Asia region, stressful regions) is the most probable. Scenarios were selected.
