Netanyahu is trying to stay out of prison, like Trump, so he needs conflict but not too much (losing support from his right wing coalition wounds end him) to seem strong and as a distraction and for political points. Iran doesn’t want war but doesn’t want to look weak and want to make a point to not let Israel think there won’t be consequences, they can’t just do nothing at all. Biden doesn’t want war in the region and he’s focused on negotiations to calm everybody down, preventing escalation. If Iran had hit something important it almost certainly would’ve escalated to war.
