It’s two years since the start of the Saudi-led military campaign in support of the Yemeni government which was ousted by Houthi rebels. The war has been a disaster for countless civilians. Thousands have been killed and the country is on the brink of famine. The UN is calling it a humanitarian crisis. And yet it’s far from clear which – if any – of the multiple nations and groups involved in the conflict is working to end it. In other words, our question this week, why is no one trying to stop the war in Yemen?
