The conflict in Yemen, which is rapidly piling up a disturbing body count, is remarkable for the overt and prominent role played by Saudi Arabia which is the power behind an impressive coalition of regional states which support their campaign, largely seeing the conflict as a proxy for a campaign against Iran.
But while, understandably, Riyadh does not want to compromise on its regional sphere of influence, the Yemen conflict is also being used for internal political consumption. Saudi Arabia projects confidence, but in reality it is not a very stable nation. The threat of tribal, sectarian and class paradoxes within the kingdom is much graver than the threats imposed by so-called Shia Crescent.
The Saudi political elite either ignores the prevailing challenges or tries to compensate for internal problems with an assertive foreign policy. Using foreign policy as an effective tool to control internal dynamics has been common practice for a very long time in the region an external enemy can be used to generate unifying nationalism or to legitimise a security state. Its an especially useful tactic for authoritarian regimes.
For Saudi Arabia, the ramifications of this conflict go way beyond Riyadhs regional ambitions. The war in Yemen has significant internal political implications for the new king and his new political entourage. King Salman bin Abdulaziz Al Saud took over his position in January 2015 and in less than three months he embarked on the most ambitious Saudi foreign policy in years. Although Salmans early political manoeuvring suggest that foreign policy is going to be his main preoccupation, there are also various factors threatening the stability of his kingdom internally.
