Israel would only attack Iran if the United States fully commits to it with full force. There is no way on earth Israel will attack all alone. Reason is that Israel's knows exactly that it will invite death & destruction of Israel if it goes to war.
The Iranian attack was designed to minimize any damage but at the same time deliver a message to Israel. All those cheap / loud drones were sent to tell Israel what we are coming, we are starting the attack, those were meant not just as distraction for their air-defense but also as an advance warning to get prepared and start shooting these with your expensive SAMs. Iran already win if we see the costs involved, For every 10K USD drone, a million dollar missile was fired by Israel. In the process Iran also easily penetrated through the air-defense and attacked the airbase which was it's intended target. BMs so accurate at such long ranges despite GPS / EW jammings is feat in its own sense. But also tells that those missiles were either without a payload or very light explosive material. Those BMs can carry very explosive & heavy warheads. If Iran intends destruction in their next waves, it will definitely cause some heavy destruction. For any next attack, Iran will not give advance warnings as it gave in its last demo to the US and to the neighboring countries. Iran gave many hours earlier warning, basically to tell Israelis / US to get ready.
I can only laugh at those fools who are revolving around 'interception rate'. Even credible western analysts are acknowledging that those drones were sent at first place to be intercepted. It was all by design. I mean where's your IQ when you say oh interception rate is so high? Do you really think Iran intended those 300+ projectiles to make an impact and cause wide scale destruction across Israel ?? Do you think Iran wanted a full scale war?? Even a kid can understand that Iran wanted to avoid full scale war. The whole operation was designed to minimize the damage but only show the capabilities that Israel is well in range and those GPS / EW jamings won't do a shit. Iran only established that their cheap drones can overwhelm & exhaust Israeli AD which can't keep up logistally and in the process Iranians can even break through their defenses at their higest level of alertness / prior warnings and full allied support. I don't think Israel is foolish enough to attack Iran all alone, when US already has said they are not interested to be dragged in this war.
