Thanks for your post. Could I go so far as to say this is a Sunni/shia proxy war( Saudi’s vs Iran) or is there more to this?
“Could I go so far as to say this is a Sunni/Shia proxy war( Saudis vs Iran)”
Sunni/Shia is a big part of it, but both Iran and the previous Saudi jihadi surrogates (like ISIS) have wider aspirations, even though they hate each other the most. In Yemen, it is more directly Iran vs. Saudi Arabia/UAE (political). In Syria or Iran it is relatively more Sunni vs Shia (sectarian) - but in every case Iranian Revolutionary Guards Corps (IRGC) has a commanding role on the Shia side..
Across the region, the Iranian/Shi’ite side is much more centrally commanded by the Iranian regime. On the Sunni side, many of the jihadi groups have gone off on their own, and are only loosely influenced by the Saudi Government. Many of them were self-generated based in the Wahabbi doctrine, but never under direct Saudi control.
In Yemen though, the Sunni side are directly operated by the Saudi and UAE Governments, as regular military forces (albeit with many foreign mercenary troops).
In Yemen, the Houthis are a variety of Shi’ite that is pretty far from the Iranians - almost Sunni. They are really more a political/military proxy of the Iranian Government, than a religious/ideological one. To a large degree, the Houthis had a long term political grievance within Yemen, and just took Iranian support, because they were the only ones who would support them.
The Houthi/Iranian side also employs a bunch of foreign mercenaries (albeit lower skilled black African mercs, versus the relatively high-end mercs the UAE and Saudis hire, like Columbians and Morrocans in the rank and file, with Western and South African advisers).
