From IISS pointing to the fact some missiles have decoy war heads . So the 55% interceptions were probably less much less when considering what was actually intercepted.
“One possible explanation for the very large (1,500 to 1,800 kg) payload claimed for the Khorramshahr is that it is intended to carry multiple warheads or decoy apparatus to confound missile‑defence systems … it might be cost‑effective for Iran to seek to defeat these systems with missile salvos and decoys.”
JINSA points that there were 57 impacts . It doesn’t even try to say some missiles didn’t reach Israel. It parrots the same BS that over 300 missiles hit open fields . No mention of strikes on military sites ; 57 strikes on civilian installations/ population centers . supposedly, they knew exactly which missiles to go after and they could determine which ones were not going to hit a value target.
In the CNN video you can clearly see that five interceptors were used and they still were not able to stop the missile from striking. There’s another video that we’ve all seen that shows as many as 11 interceptor being fired for one missile and they still couldn’t stop it. So how many interceptors were actually fired .
The inference from these numbers is that they had no choice, but to let the missiles strike because they could not intercept them or had to save the interceptors for the very high value targets.
