Saudi-led Coalition's decision to Support Legitimacy in Yemen has come to help the legitimate authority in the country, enhanced by UN resolutions, Arab charters and joint defense treaties in addition to the formal request made by the legitimate President of Yemen Abed Rabbo Mansour Hadi to the leaders of the Gulf Cooperation Council (GCC) for Arab States so as to repel the aggression and save the Yemeni people. Coalition's response came to deter foreign ambitions represented in Iran's blatant interference in Yemeni affairs and its support for the coup militias to control the capabilities of the Yemeni state and threaten regional and international interests in the Arabian Sea. The 26th of March 2015 was a strategic shift in the balance of power, when the Kingdom of Saudi Arabia responded to the request of Yemeni President Abed Rabbo Mansour Hadi, after having submitted a request to the leaders of GCC's Member States to intervene, through a message in which he referred to the severe deterioration and very dangerous security situation in the Republic of Yemen as a result of hostilities of Al-Houthi militias backed by regional powers aiming to extend their hegemony over Yemen to make it as a base for their influence in the region. In that message, the legitimate President Abed Rabbo Mansour Hadi appealed to GCC states to stand by the Yemeni people to protect them, where the request was based on the principle of self-defense stipulated in Article "51" of the Charter of the United Nations; the Arab League Charter and Treaty of Arab Joint Defense to provide immediate support by all necessary means, including military intervention to protect Yemen and its people from the ongoing Al-Houthi aggression. All of these legal and legitimate evidence have supported the historic resolution of the United Nations Security Council No. 2216 issued in the mid of April 2015, which called Al-Houthi rebels to fully implement the two resolutions No. 2201 and 2204 and to refrain from taking further unilateral actions that could undermine the process of political transition in Yemen. The resolution, which was supported by 14 members of the Security Council, demanded Al-Houthi militias to stop immediately and unconditionally from all use of violence, withdraw their forces from all regions, including the capital, Sanaa, abandon all weapons they seized from the military and security institutions, including missile systems, stop all actions that fall within the scope of legitimate government's authority, and refrain from any provocations or threats to neighboring countries as well as release the defense Minister Mahmoud Al-Subaihi, all political prisoners and all persons under house arrest in addition to end the recruitment of child soldiers and demobilize all the recruited child soldiers in their ranks. The resolution also called on Al-Houthis for commitment to the initiative of GCC's Member States, the results of the comprehensive national dialogue conference and the resolutions of the Security Council and accelerating negotiations to reach a compromised solution and the full implementation of the signed agreements and commitments that have been undertaken to achieve this goal and promptly stop the violence. Moreover, the UN resolution called on all states to take measures to prevent supply, sale or transfer of weapons directly or indirectly to deposed Saleh, Abdullah Yahiya Al-Hakem, Abdul-Khaliq Al-Houthi, entities and individuals who are under sanctions emanating from their territories, by their nationals or by using ships or aircraft flying their flag, including a ban on arms, ammunition, military vehicles and equipment as well as paramilitary equipment, spare parts, technical assistance and training in addition to the financial aid, and everything related to military activities, the provision of any weapons, or armed mercenaries whether their source is their territories or not. The UN Security Council's resolution was considered supportive of the Yemeni people's right to build their future through dialogue away from the threats of force, which Al-Houthi militias and those of Saleh though that they can impose their absurd options on the Yemeni people. The UN Security Council's resolution also came to confirm the stand of the international community's will along with the will of the Yemeni people, whose all their national forces of various political affiliations and intellectual backgrounds have worked for the success of the national dialogue, yet the armed militias came to turn against the outputs of the national consensus.
