Gets even spicier when looking at southern Saudi Arabia and Yemen. Saudi’s have a lot to worry about. The Iranian proxy has been well supplied for years, and now, I’m sure, there are IRGC “advisors” on the ground as well.
My understanding is that the Iranians have pulled most of their people out of Yemen, to focus on Iraq, and then Syria.
The Saudis will win in Yemen, but it is a very effective holding action for the Iranians, while they fight in Syria. Unless there is a deal, the Yemen War could drag on for a year or more. In the Houthi heartland, it could simmer long after the Capitol/country is conquered.
There is a big change in Turkey this last week, with Erdogan snatching the election, so he can rewrite the constitution again (this will be his third go). We will have to see if the Turks now go to crush Kurds, the Iranian/Assad troops, or both. They are talking about ramping up their involvement, and they have some pipe-hitting military capability.
