The war is seen as a revival of the Muslim duty — in particular, the Saudi duty — to purify religion from the "Majus" (a pejorative term for Persians), the Safavids and the heretic Shiites. Less racist and religiously bigoted opinions invoked Arab nationalism to defend the Arab identity of Yemen. There is no room for dissenting opinions, as opponents of the war, or even those who question the war's logic, are labeled traitors against the nation and religion. Suddenly, Saudis were able to unite over a controversial intervention in a domestic Yemeni conflict. Saudis seemed desperate for a war with Iran, albeit through a Houthi proxy. As long as this war remains confined to Yemen's rugged mountains and destitute cities, and so long as it does not spill over to southern Saudi Arabia, Saudis are happy to witness the destruction on their screens and Twitter accounts.
The war on Yemen may well be what Saudis — both commoners and royalty — have wanted for a long time. A victory over the Houthis is important for domestic reasons, not least to mend internal Saudi divides, but also to save the Saudi leadership from embarrassment over its complete failure to score victory over Iran in Syria and Iraq, and over Washington’s new policy to mend its ties with Iran and possibly lift sanctions.
