A Saudi blockade has crippled the economy in the north. But the Houthis compound the suffering. They divert aid and sell it for profit. The UN’s rollout of covid-19 vaccines in the north has been suspended because the Houthis want to control delivery. Across the country, at least 400,000 Yemeni children could die of starvation this year without urgent intervention, warned four UN agencies in February.
The Houthis still manage to keep their war machine humming, though. Smugglers haul fuel to the north from ports in the south that are controlled by the government or its nominal allies. Houthi checkpoints double as customs posts, raising revenue to pay fighters. Iran uses the same route to smuggle “significant volumes of weapons and components to the Houthis”, according to a UN panel of experts. It supplies parts for their drones and missiles that are used to attack Saudi Arabia.
Marib’s loss would further demoralise the pro-government coalition, which is already fragmented. Yemeni soldiers complain about unpaid salaries and a lack of arms, while the president, Abd Rabbo Mansour Hadi, remains in gilded exile in Saudi Arabia. A separatist movement called the Southern Transitional Council (STC) is ostensibly a member of the coalition, but it has fought the government for Aden and now controls much of it. Many of the STC’s leaders cheer on the Houthis. Some of the tribes around Marib flirt with them, if only to extract more cash from the government.
The government’s international backers are losing interest in the war. The United Arab Emirates pulled most of its troops out of Yemen in 2019. Shortly after taking office, President Joe Biden said he would end “all American support for offensive operations in the war in Yemen”. The Saudi campaign, launched in 2015, has fallen into a quagmire. Instead of curbing Iranian influence, as intended, the war has enhanced it. In an interview last month Muhammad bin Salman, the Saudi crown prince and de facto ruler, appealed to the Houthis to join him at the negotiating table.
