American agencies will be tight-lipped.
You are wrong if we go by detailed public/private sector Western publications on Iranian missiles before. Here is IISS, a government funded NATO-affiliated think tank of UK/US experts obsessing with Iranian missiles for pages and pages. I can give more examples where even materials of jet vanes of Iranian missiles are discussed.

So yeah, Americans or NATO-affiliated publishing groups have never been tight-lipped about Iranian capabilities and their own counters to that.
Nothing concrete about K-4 from your side either.
You are wrong. They even showed its MaRV's inside.
Even if it is IRBM class, small and/or relatively soft stuff such as PENAIDS/bomblets will not survive during the reentry process.
Bomblets are never deployed at re-entry. Thinking that a 80 x 17-20 kg bomblet package will open-up at exo-endo transition phase at 50-100 KM is just absurd. The RV releases them over target much later in the terminal phase otherwise they will scatter here and there.
In case of K-4, PBV dodges Exo-atmospheric HIMADS, while cluster munitions dodges/takes out shorads. Its an almost perfect weapon tin its class to destroy airbases. 30 x K-4 strikes means an AB is gone.

Besides, penaids are not EXCLUSIVELY deployed during re-entry either, it depends upon what kind of air defense the designers of the RV are trying to defeat. If it's a Mid-Ranged ABM layer then Penaids are deployed endoatmospheric or terminally, if ABM is HIMADS then case is different.
I gave the example of the relatively much downgraded Iranian Rezvan PBV (Qiam-3 in IRGC, Burkan-3 in the hands of Houthis) it flew over PAC-3 unchallenged in 2020. K-4 is just another level animal.

We were told PAC-3 is just invincible
K-4 RV is your best bet and kinetic option, therefore.
We have a far more dangerous weapon called Sejjil-II/III in the arsenal for the IRBM strike. Apart from the extremely accurate solid fueled systems originating from the Fateh Solid fueled Quasi ballistic Family that gave birth to Kheybar Shikan and Fattah Skip/HGVs, Sejjil Family forms the larger MRBM/RBM/SLV core of Iranian strike forces and space program.
Its an entirely different family of solid fueled MRBM/IRBMs thats now 15-17 years old. What is its latest version? what is the trajectory, how much lateral vectors its MaRV can produce? no one knows.
Some experts like Norbert Brugge estimate that with a Kick-off TVC stage like in Iranian SLVs its range can be around 3700 KM (or with a powerful booster like Raafe)
One of the tested SLV's that shares Sejjil's origin.
OK, I have rechecked this side on Google Maps. It turned out to be 3832 KM in this case. Still, engaging Diego Garcia from this far in a comprehensive way is not an easy task.
I told you, your initial estimates were just wrong. You may have been measuring distance from some city in Iran.
The island is very thin and US can put significant defenses on it if necessary.
Well they did not, the last time IRGC struck them.
I have pointed out before that American missile defense systems such as THAAD and AEGIS can take out an RV in exo- conditions or outside Earth.
Conjecture. Exoatmospheric manuverability can negate tracking while Iranian missiles are constantly showing mid-course corrections in recent times. K-4, Rezvan, Fattah, Ghadr all do midcourse dance.
One example.
Time to dial down the rhetoric and be realistic.
You were claiming Diego Garcia is out of the question. I proved to you that it's possible.
You cannot win a war with conventionally-armed ballistic missiles. Time has shown this repeatedly in different fronts around the world. Iranian model of warfare has deterrence effects but it is not going to produce desired results in offensive capacity. But you people will not get it until war comes to you. Some people are destined to learn things the hard way. I do not have virtually endless time and appetite to address Iranian "theories." Carry on.
I don't do political commentary.
