Sounds like the strike was significant, but not decisive. In particular, they can't target the plant in Fordow.

If anything Israeli action reduces the likelihood of any deal and increases the possibility of the aytollahs quickly rebuilding nuclear infrastructure (article implies they have the capability) and going full nuclear.

I read about some military experts that were interviewed by a Norwegian paper. They essentially said that Israel is doing its best to chip away at Irans nuclear capabilities from several sides: Targeting everything from scientists to electric infrastructure, to centrifuges and the facilities themselves.

However, they seemed to think it was completely unrealistic that Israel would be able to prevent Iran from developing nuclear weapons by military means. They even speculated that even the Israelis don't see it as realistic, but that they're attacking in an attempt to delay the inevitable and hopefully drag the US into the war before it happens.

A point they made is that the facility at Fordow is too deep to be reached even with the world's heaviest bunker-busters. Iran is apparently also working on a new facility that will also be ≈ 100 m deep in the mountain.

Isreal: "This is the start of a weekslong campaign"

Isreal, day 1: decapitates military, destroys air defenses

Day 2: Now able to fly with impunity, strikes military and energy targets in broad daylight

News media, day 3: "Isreal has failed to totally end all Iranian nuclear efforts!"
