Yes, those things existed and we knew they went above 60%. Not sure what your point is
Yes. Israel wouldn’t have agreed to a ceasefire if they believed Iran still had the ability to enrich uranium.
Why would you believe otherwise
depending on your world view I see several reasons they would stop. this is not a single thought, but rather just multiple options, it could be one, multiple, or none of them.
1. they ran out of options to continue the attack. which is why they needed us in the first place. with no more weapons, or targets they could hurt, there was no reason to keep striking things to strike them.
2. It was never really about taking all of their capacity. it was about making a strike to be seen. a much more violent version of those Iranian strikes that hit dirt around our bases. definitely more real, but the intent was never complete destruction. Israel needs a boogey man just as much as any other government for fear mongering control.
3. continuing to attack would have completely destabilized Iran and the region, creating another ISIS. Israel wanted to avoid that.
4. continuing to attack could have drug in other combatants.
5. continuing to attack, especially over other nation's airspace, could have impacted their nominally good relations with those neighbors.
6. there was some other goal in mind, and the nukes were just justification and distraction. getting Iran to stop funding Hamas, Hezbollah, and the Houthis would be a major win, regardless of nukes.
7. they just wanted us involved. once they had that, they didn't need any more. the US had been pulling away from their support of Israel. public opinion was tired of funding them forever. once we get involved and the dollars start rolling our politicians fall in line with support for Israel as it becomes their meal ticket. the renewed dollars offsets any issue of public opinion.
8. they realized their attacks weren't having the impact they wanted on the nuclear program in Iran. and this is just a pause/reevaluation.
