The present article aims to study the strategies of the Islamic Republic of Iran towards the Yemeni crisis. After explaining different factors involving in creating the crisis in the country, in terms of the Lucien Pye's theory of crises, the authors further describe Tehran's orientation and policies toward the Yemeni crisis, taking into account the values and principles of the Islamic Republic of Iran's foreign policy and considering the security circumstances in the region. In order to assess the strategies of the Islamic Republic of Iran and Saudi Arabia's efforts to securitize the regional issues at the present time, the article takes the "security complex theory" of Bary Buzan as its conceptual framework. In fact, Riyadh, since its formation in 1932, has been pursuing a securitization policy in Yemen, in pursuit of its interests and policies in Sana'a. Now, after the increase of the Islamic Republic of Iran's regional power, Saudi Arabia, through the continuation of its hegemonic policy, is trying somehow to present Tehran as the factor of destabilization and securitization in the region. Therefore, the article, after explaining the policies of the Islamic Republic of Iran, based on peaceful and participatory coexistence, proposes the de-securitization strategy, aimed at transforming the security environment in the Persian Gulf region.
