Regional and Transatlantic Governments and the Yemeni Geopolitical and Security Crisis with an Emphasis on Iran and Saudi Arabia and Allies

Southwest Asia has been the focus of attention and, of course, action for geopolitical reasons and the existence of religious-ideological and energy centers for powerful countries. The role of the two major countries of Iran and Saudi Arabia in this challenging area has traditionally been highly effective in addressing the developments in this region, as well as in the final decision-making process of the major beneficiary countries. Since Yemen is located at the south of Saudi Arabia, west of Oman, east of the Red Sea and north of the Gulf of Aden, it has doubled its significance and is dominated by a strategic strait that is vital for the Horn of Africa, Saudi Arabia and, in particular, Egypt. The Yemeni people have long had religious attitudes, including Shi'a and Sunnis, which is currently the majority of Zaydi's Yemeni people with Shafiq jurisprudence. Ismaili and Sufi religions are in the next rows. This paper, by descriptive-analytical method, seeks to answer the main question: What factors cause the crisis in Yemen which led to the expansion of the crisis? The geopolitical, security and ideological rivalries between Iran and Saudi Arabia in the region, and in particular in Yemen, have led to a suspicion of Saudi Arabia's traditional hegemony. Because of the role of the identity and the spirituality of each of the two countries, they sought to influence their own strategy based on their strategy. The material presence and ideology of Wahhabism led by Saudi Arabia in Yemen has been undermined by the message of the Islamic Revolution and the resistance movement, which has complicated the crisis.
