I wonder how many got through in reality.
90% got through. Israel nor the western powers have the tech to intercept hypersonics, Roch. There is ample footage of dozens of missiles landing with none intercepted. This attack was a huge step up from the previous attack which used mostly slow drones and subsonic missiles. You may wonder, and ought to, why it was that Iran used only slow drones and subsonic missiles that were almost certain to be mostly shot down in their previous retaliation.
The previous swarm attack forced the Israelis and allies to "show their hand" in terms of Air Defence, or at least a substantial part of the map. Patriot systems in Jordan, RAF jets flying from RAF Akrotiri(Cyprus) and US Navy destroyers as well as locations of AD in Israel. The slow drones and missiles by swarming the defences and eliciting the required response also allowed the few more precise and faster missiles to reach their target as well as mapping Israeli AD. Much the same game is played by NATO with their drone and missile provocations into Russia. It is worth adding, however, that Russia has huge strategic depth and the Zionists don't.
A further part of the strategy of escalations in the attacks demonstrated by Iran is spelt out explicitly and the message is received by those who need to receive it.
First attack- 200 or so projectiles that can be intercepted, with a dozen or so thrown in that can't be intercepted. Result-minimal damage but carrying the implicit and also explicitly spelt out warning that next time it might be 200 or so exclusively non interceptible missiles.
Second attack- 200 or so exclusively non interceptible missiles(who could have seen that) targeting exclusively military targets and avoiding civilian and infrastructure. Result- more extensive damage than previously but none to vital infrastructure but carrying the implicit and again explicitly spelt out warning that next time it could be a magnitude greater(2,000 or so non interceptible missiles aimed at Dimona, Haifa chemical and de-salination plants as well as US military bases in the ME should they intervene.)
The Zionists and their sponsors are reaching the end of the road. Victory isn't counted by how many civilians you slaughter or hospitals you bomb. They are being defeated militarily, economically and diplomatically. The side that celebrates the slaughter of innocents is not the side that is winning.
