@serge About 3, with Bibi nobody knows really... but I tend to thing that maybe it is just an additional point.

About 4, no. There are movements against the regime in cities, outside of that only relevant movements in Kurdistan and Beluchistan.

On the other side, that should not be the job of Israel. If Israel enters in this dynamic in a few months we have another senseless eternal war like in Gaza.

About 5, difficult to say, but I tend to think that it should be connected to all the middle east. Only a regional diplomatic solution will bring a middle-long term peace.

@serge

About 1, I would say yes or they were giving fast steps. At least that was the opinion of the Israeli security services since some months and the last report of the IAEA. After the report of the IAEA the Iran government declared that the agency works for Israel of course...

About 2, Iran with nuclear weapon capacity would be a big factor of destabilization. Another thing that goes forgotten is that a big contribution to the destabilization are Iran's proxies, Huties, Hezbollah, Iraq militias.... The change would be that those proxies would have the potential protection of a nuclear umbrella.
As a criticism here... they are attacking Israel since long, the huties yet almost every day one or two times. But it doesn't seem to be considered as "destabilization" but just a part of the local landscape.

@serge but that is a usual tactic in cases like that. It was implemented by the European union in the past Trump presidency, and currently a similar measures are being prepared for soon implementation.

Of course, the EU uses other language, but there are new tariffs for branches where their main production and management places are in the deep red states.

I am not saying I am for it, anyway I'm not in the US, Canada or Europe and I am always for free trade, but it is not the first time measures like what the Canadian party proposes have been implemented.
