1) PRsM
2) ATACMS
3 Tomahawk
4) JASSM
5) We have stealth planes that can just put glide bombs on targets, all while staying far out of counter “battery” range
6) we have stealth planes that can launch cruise missiles, and bigass bombers that can carry like 26 at once
7) every above option is more mobile than Iskandar, planes by orders of magnitude
8) plane delivery can also recon/confirm targets, conduct secondary missions like SEAD or EW, call off or redirect shots as needed, and have more varied payloads for COIN and such thanks to not relying on an incredibly fast delivery vehicle that will cause a minimum of kinetic damage inherently
9) we signed a treaty saying we wouldnt make them back when we might have found use for them (before we had hundreds of stealth planes)
Rebuttals:
>but planes cant get on target faster than a supersonic missile
Yes, they can if theyre running CAP at all times like they have in every single US operation since WW2
>but Iskandar has decoys american missiles lack
JASSM and its delivery vehicle are both at worst low-observable and can ground skim, LRASM is supposed to be so sneaky that mounting them on an F-35s external pylons doesn't significantly compromise it, plane delivery can perform SEAD and eliminate or distract air defense, etc etc
