Commander Abd Al-Hussein Mejdami killed in the Ahvaz region by armed men.
So it seems the Ahvazi Arabs will join up whenever the Kurds re-start their insurgency in the fight for independence.
Also, this is where the oil in Iran, if an insurgency began there, the regime loses all hopes of surviving.
Let's see, So we now have renewed clashes with the Kurds starting in November with the potential for a full insurgency.
And now we might see another insurgency in the Ahvaz, alongside the already existing mass protests and uprisings there.
Only left to see the Azzari Turks and the Lurs join up and the entire Zagros is gone.
This would be more than enough for the regime to fall in the core due to the uprisings.
However, if the Balochi will rise up as well and re-start their insurgency, this would be a bit problematic since it would immediately spread to Pakistan.
If the Balochi began a cross border armed insurgency, they'll probably receive help from the Pashtun tribes along the Durand Line, which in turn could turn into an alliance with the Taliban and the Hazara to incircle the American forces, bring down both Iranian and Pakistani governments (The Pashtun and Balochi both claim a large mass of lands in Pakistan which they've been fighting over for the past century), and potentially pursue independence or federalization.
On the other end of the map, we could see the Turks (Turkey) involving itself in North West Iran to prevent Kurdish independence, which in turn could spiral into another Turkish-Kurdish war, this time from Iran, Iraq, and Syria.
We could also expect Russian intervention in the north to prevent Azzari independence and merger with Azerbaijan as the Azzaris have been trying to do for around 5 decades now.
If an insurgency did break out throughout the western mountain range, which so far everything indicates it will since the past insurgencies have started due to much lesser spark, we could not only see the end of both the Iranian and Pakistani states, both shedding their imperial remnants (Iran of its past empire, and Pakistan of the artificial British borders) and returning to the original nation-state borders, but we could also see the conflict with Kurds reigniting throughout Kurdish territories, as well as a break in Turkish-Russian relations due to the Azzari pursuit of independence.
However, we might see an Indian support to all these actors as the Indians would love nothing more than not only to fuck with the Pakistanis, but also to establish a corridor to central Asia for gas and oil supplies.
Also, it would be in India's strategic interests to support these insurgencies and independence movements as it would be able to bring Chinese expansion in the western half of the continent to a halt.
It's unclear where the Gulf states will stand as they would obviously support the insurgencies in western Iran, but would likely fight against those spreading to Pakistan.
