On March 26, 2015, Saudi Arabia launched airstrikes on Yemen with the aim of restoring the rule of President Abd Rabbo Mansour Hadi and eliminating the Houthi movement. Located on the Bab al-Mandab Strait at the southern entrance of the Red Sea, Yemen has always constituted a cornerstone of Saudi foreign policy. Since the Kingdom's foundation in 1932, the Saud family (al-Saud) has striven to expand its control over its southern neighbor and prevent it from threatening its interests. In 1934, the first modern war broke out between the two Arabian states. The 1934 Treaty of Ta'if put an end to this military confrontation, ceded the three provinces of Asir, Najran and Jizan to the army of Ibn Saud, and established a peaceful coexistence between the two countries.1 Since then, the Saudis have avoided open, large-scale confrontation, and have instead maintained a precarious stability in Yemen through meddling in its internal politics, backing certain local groups against others, using Yemeni guest workers as leverage, buying off tribal leaders, and conducting limited, occasional military operations, especially over border disputes.
