Few points... what happened when Iraq nuclear reactor was destroyed on 80s - everybody was mad about it - later thanked Israel..
Honestly, we doing everybody a huge favour - because the rest of the world decision making and standing against existential threat isn't very good. And Iran with Nukes is the threat to entire world not Israel alone.
So what USA and Europe should do is not to ask how to deescalate, but rather say thank you and please give us a list of targets for B-52s, B-2s, F-18s, F-35Cs, and Rafals so we can ensure that nothing is going to be missed especially since IAF has already did the job of gaining a full air-superiority.
And honestly... it should be done way-way before, not when they are so close to getting Nukes
