This is rather cinematic then anything else and very filmsy.
The Azerbaijan part was wrong I don´t think they would invade but if they were to invade it would certainly not be with 75k but rather upwards to 300.000 men but I don´t see them attacking at all there is no political incentive.
Also the unprovoked GCC attack will mean they will likely mean the GCC will invade from the Ocean with upwards 1 million men. This will involve Egypt and other multiple players
Besides Russia nuking to deter Azerbaijan sounds very unrealistic because you said to prevent turkish influence in the caucaus there is already that influence and by Eastern Azeribaijan falling it doesn´t make any sense. Turkey has access to caucaus via Azeribaijan it is kinda of redundant.
In this scenario you made Iran out to be rambo where they are attacked from everywhere which is unrealistic of itself because they won´t be attacked any of the players you listed. Except maybe the Peshmerga and that is maybe but if all the actors you named was to conduct an incursion it will be over 2 years time all of it will fall but that is not the scenario nor realistic politically in the current scenario.
Here is how I see it happening if it was to unfold.
The US, UK, France, Syria and Peshmerga could invade Iran. Where Sharaa becomes their most staunch and important ally they will solely attack from Iraq which means Iraq itself will get invaded in the process. American forces will penetrate from Syria into Iraq together with HTS, FSA, SDF all joined in the Syrian armed forces this is the most realistic scenario. These are some of the most battle hardened forces in the region now.
