> For Jordan I'm mostly thinking about their past history with Palestinian...

Jordanian Palestinians tend to be middle and upper middle class now and cornered the Ex-Im business with Israel and the US (most Arab goods in the US are "Made in Jordan" for a reason, and why "Made in Jordan" textiles have become so common now at Costco and Walmart).

Jordan also neighbored a similarly industrial country that collapsed into a decade long civil war (Syria).

> What do you think the possibility of Kurds getting a piece of land from Iran

Kurds are not uniform. The KRG (Iraqi Kurdistan) is fairly socially conservative as is Iranian Kurdistan. They are also extremely pro-America (the US protected the KRG since 1991), pro-Israel (Iraqi Kurdish Jews of the Barzani and Talabani clans are overrepresented in Israeli politics and defense careerists), and pro-Turkiye (they are a counterweight against Apo's PKK).

I think it is likely we will allow a KRG dominated rump state form around Ilam-Kermanshah-Sanandaj-Mahabad. We will likely see a similar thing arise in Iranian Azerbaijan with Turkish+Azeri backing. Iran is already de facto nonexistent in much of Sistan-ve-Balochistan. Iraqi Shia Arab militias will most likely end up backing a rump state in the portions of Khuzestan neighboring southern Iraq and Kuwait.
