Depends on how granular you are being. Israel can't do this without the strategic alignment it enjoys from the U.S. (along with the explicit approval historically for such things, money, investments, arms, etc.).
Did Israel have to call Daddy America and ask for permission to go to the movies and say they will be back by curfew? I don't think that's necessarily true. Especially when you consider the following:
1) Trump sucks
2) Bibi and Trump are already kinda fighting in a petty frenemy way when Israel got rebuffed weeks ago during the UAE/KSA/ME tour and by dealing directly with Iran and Houthis.
3) It's been reported that Bibi thought Trump was being played (strung along by Iran) and he's too dumb to know it and didn't comply to a direct request from this administration to not hit Iran yet
4) The mutually assured destruction chess pieces Iran had are all nerfed to complete levels of ineptitude so there is no "get back" now with Houthis, Hezbollah and Hamas all being castrated.
5) Israel / IDF are some bad mother--watch my mouth!
But seriously Mossad/IDF/Israel have shown some scary tight operational vigor for a country and population it's size. It's no wonder Wiz sold for $28 billion (j/k).
