What’s going on in Yemen is incredibly complicated. I’m not condoning everything Saudi Arabia is doing there, far from it, but to call it out as a good vs evil war is frankly a simpleton view. Saudi is bad there. Everyone is bad there. It’s a huge mess. But I think it’s important to recognise that the Saudis aim is to restore order in a neighbourhood country, to prevent Iranian influence from growing and to suppress violent Islamic fundamentalism.
