The US and Israel were lucky that Iran built their Fordow plant only 50 meters underground. What will the US do when Iran rebuilds it far deeper? They have a coal mine going 1200 meters deep.
Iran is technologically far more capable than North Korea, which ultimately succeeded in building the bomb. The US knows this and wouldn't have started this war if Israel hadn't done it first.
The first Iran deal in 2015 was not perfect, but it would have provided some guarantees for 15 years. If Iran is determined, how many years has this bombing bought? If I had to guess, Israel is back calling doom ~3 years when the US is having new elections.
Israel doesn't want the removal of the Iran sanctions, why would they? This means whatever deal the US makes with Iran, it's not going to be good enough for Israel.
