The security of activists, especially in the regional arena, is regarded in international relations studies as one of the most agreed concepts in the country's foreign policy; in particular, political security issues following the developments of the Islamic revolution in the region are a sort of interconnectedness between regional actors. The dilemma has led to an escalation of security issues in the Middle East. For this cause, international players with shared interests in the Middle East today have traditionally concentrated on regional security assemblies in order to ensure their existence. One of the security issues in the Middle East in this respect is the Yemen crisis, which may expand the security of the crisis to other regions. Thus, as an aggressive player and regional authority, the Islamic Republic of Iran has tried to pursue a protection and defense approach to the nation-to-state of Yemen in order to preserve its internal stability from the eruption of the crisis in Yemen. The aim of the debate on the Islamic Republic of Iran's activities was therefore on topics such as attempts to sustain the axis of resistance, to retain its theological and regional power, as well as Yemen's geopolitical stability. At the same time, the key premise of the present analysis is that, on the basis of which foreign policy strategy can be evaluated, the positions of the Islamic Republic of Iran against the crisis in Yemen? The following theory is put forward in order to provide a reasonable answer to this question: the Islamic Republic of Iran has taken a security approach to this situation, recognising Yemen's strategic role in regional equations and strengthening its security factor in the region.
