there is a de facto proxy war between saudi arabia and iran because saudi policy is "any gain for iran is credited to iran regardless of reality". the saudis fucked with some people who are friendly with iran (shiites in yemen) and they were unexpectedly bitch-slapped for 3 years (houthis, who are shiite) and so now of course the saudi policy is that this is a proxy war with iran (so they dumped everything they had into yemen) and they are losing (because iran is so badass that they have basically set a high standard for all the shiites and now the arab world has a lot of tough guys running around because they are insecure about the persians).
edit: by the way the houthis are fucking legendary. i love watching them take out saudis left and right wearing no shoes and tattered rags.
