It is quite fascinating to see the similarity between Game of Thrones and the Middle East.
What is happening in Yemen helps clarify the situation of who sides with
Saudi Arabia (AKA the Lannisters in the Game of Thrones) and the vassal Gulf States (apart Oman) are actually paying Sudan and Egypt to wage their war. And they are trying to call in their credits to Pakistan too.
Iran is helping (not as much as they want you to believe) the Houthis in Yemen and other parts reported by the media (Syria) or not (not reported by the media there has been some terror attacks in Medina, Saudi Arabia) – it is trying to assuage the US (US nuclear deal is actually quite favourable to Iranians if you look at the details….that is because the US wants to disentangle itself from the Game of Thrones).
Saudis are reciprocating (a terror attack from Pakistan killed 8 Iranian border guards), but lightly as Iranian militarily is much stronger.
Turkey needs to seen helping the Saudis, but in reality is wary both of Iranians and Saudis.
Oman is kind of watching who is winning – technically siding with Egypt, but neutral.
Israel is siding with the Saudis as they offered an airspace canal to bomb Iran, if they want to (with a strange ally of Azerbaijan).
Islamic State and Al Qaeda are proxies went crazy.
As they would say in the Game of Thrones: Valar Morgulis (“every man must die” in Game of Thrones)
