Iran’s nuclear facilities are too hardened to be directly rendered ineffective by conventional Israeli airstrikes, even multiple ones... and possiby even by unconvetional (read: bunker-busting) strikes.
But, those facilities prob aren;t self-sustaining. They need fuel, maybe electricity, people, etc. And they also need to be run by a goverment & military with a leadership that is still alive, and one that is not overturned by a people who are begging for the pain to stop.
Hit their refinery and electric plants too the.
