Syria's strategic position in controlling security threats against the Islamic Republic of Iran

The developments in West Asia and the spread of popular uprisings in the region have quickly led to different decisions by actors in their foreign policy. Iran's geopolitical capacities and its national security have been strongly influenced by the regional environment of the Middle East. After the Islamic Revolution of Iran, the formation of a coalition of Arab countries living on the periphery of the Persian Gulf under the leadership of Saudi Arabia forced Iran to adopt a deterrence strategy through the creation of a regional coalition within the framework of the axis of resistance. One of the most important applications of any military is the use of appropriate methods to maintain regional security for it, and the theoretical basis is based on the theory that just as specific internal strategies are considered to maintain the country's security, overseas strategies are also used. The present research, with descriptive and analytical method, specifically seeks to answer the question, what is the position of Syria in the deterrence strategy of the Islamic Republic of Iran against regional and international threats? The findings of the research indicate that Iran has defense layers in Syria, Iraq, Lebanon and Yemen, that Syria has not taken an aggressive side, but its basic goal is to create a deterrent and defensive system to deal with threatening sources in the region.Keywords: strategy, regional security, Syria, Islamic Republic of Iran, deterrence
