Aden Showdown Tests Saudi Project to Tame Yemen

A week of bombing by a Saudi-led coalition has failed to force Yemen's Houthis to the negotiating table or rupture their alliance with a powerful ex-president, and the defiant militia could now claim the second city of Aden as its next prize. The fall of the southern port would be more than a symbolic blow to Riyadh: It would complicate Saudi efforts to persuade Yemeni tribal and army units to turn on the Iranian-allied Houthis. The operation by Saudi Arabia and other Sunni Muslim states aims to prevent the Houthis, who hold the capital, from winning control of the whole country and extending the regional influence of their main foreign ally, Shi'ite power Iran.
