It is possible that upper leadership is completely infiltrated by cucks at this point.
That's what it looks like, i haven't looked at this closely but apparently a lot of the mullahs and their cronies have interests in the west, be it relatives there, or money, properties etc. So personal gains/interests trump national security, or more accurate in this case national survival.
One can look at DPRK's defence achievements to extrapolate the potential of the much larger, richer and resource abundant Iran. They do have some highly competent defence systems to date, good drones and UAVs, good SAMs, good shorter range BMs and various CMs etc., but they are utterly neglecting the IRIAF, and of course they meekly don't touch ICBMs let alone nukes, not to mention some cringeworthy examples of incompetence/ignorance/corruption (like that Qaher thing or the twin tailed F-5s).
But the most they lack is a goddamn spine. I fear for Iran to be honest, the west likes to gang up on the weak, and the way they metaphorically slapped, kicked and spat Iran (numerous assassinations, sabotage etc.) in the face in the last years with only a weak reaction (i'm not sure even a single US or israeli soldier was killed in any of the much hyped iranian "retaliations") does not bode well.
Also, again compared to DPRK, you can see DPRK's enthusiastic support for Russia and active participation in the war in the Ukraine (so basically, a big middle finger to the west, apart from the whole DPRK nukes thing), while Iran, apart from giving the admittedly highly useful Gerans and possibly some short range BMs, little else seems to transpire. They should have sent not only a crapload of SRBMs, cruise missiles and other useful systems like their anti-drone SAMs, but also a contingent of troops, as a gesture if nothing else. But instead they cave in to western demands and i think they were mumbling something about "Ukraine territorial integrity". No wonder the russians are not giving them the Su-35s (the russians DO have their own issues as well in dealing with the west/zionists, but that's another discussion).
