The whole ME is in chaos nowadays. Some of those Arabian countries, such as Bahrain and Jordan, may even see civil unrest and such, which will further destabilize the region.
If the Kurdish people decided to take up the deal and go against Iran, and Turkey/Azerbaijan decided to follow suite, then it's going to be really messy.
> Bahrain
Bahrain always had unrest issues due to it's laggard economy and communal issues - this was why KSA invaded it back during the Arab Spring. Something similar is always on the table for KSA.
> Jordan
Shia are nonexistent in Jordan, and Jordan was much more affected by the decade long Syrian Civil War right across the border and some of it's largest urban areas (especially the Irbid-Daraa area).
> Kurdish people
Kurds are not uniform. The Iraqi and Iranian Kurds tend to be much more socially conservative than their Syrian brethren (Turkish Kurds are somewhere in the middle).
Turkiye also supports the KRG and PJAK as they don't support Oclanism and act as a buffer against Iran.

No one wants to admit it but that's the whole point. I mentioned this before on HN [0] - no one wants to admit this because it is a bad look, but it aligns with our interests.
We will be lucky if this does not start WWIII.
What are the Kurds supposed to get in the "deal" to go against Iran? It is pretty much guaranteed they wont get anything except betrayal in the long term, so it must be something "right now".
