Israel's hand has been forced throughout by 1. Their proximity to multiple hostiles; 2. Oct 7th; and 3. Iran becoming an imminent nuclear power.
They can hardly be blamed for neutralising threats. If only our own governments would act in the interests of their people.
Gaza was given a fair degree of autonomy in 2005, and they end up with Hamas and Oct 7th.
The big danger would be the emergence of another IS-type outfit and their attendant misery. Thinking about it, a monarchy may be the best route for Iran - it seems to be the only type of state that works in the region or at least remains stable for a reasonable period.
