Try reading about the Qaem.
Iran does not not have ICBMs just because they didn't want to.
The US does not have hypersonic missiles with highly manueverable self-propelled propelled glide warheads like Iran has.
		 
		
	 
How can Iran have wedge-wing glider missiles like China and North Korea (likely supplied or assisted by China) when the US has not put one into service. It makes me doubt Iran's Fattah 2 which is their only non MaRV or bi-conical "glider".
Bi-conical gliders are relatively abundant and appear to be a low tech branch. Iran has several, North Korea iirc has a few and China has more than I care to count. The US has a history of this development since Pershing II but the glide capability through the generations vary. The US' LRHW and "Common Hypersonic Glide Body" bi-conical types to me represent the peak of bi-conical gliders.
Okay that's biconicals, so many have them and have had them for so long. Winged and "wedge" gliders are exclusive as they come, literally only China and North Korea and known to have these in service along with this Fattah 2. North Korea's appear to be supplied or created with Chinese assistance. North Korea having complete in house capability in a field that the US hasn't completed to their satisfaction? Either the US just has much higher standards or the cost is prohibitive, or more likely, North Korea got lots of these from China. China has had several public programs for gliders usually handled by universities. The military only showed DF-17 and YJ-17 as military service gliders but the PLA is likely to have many more that they haven't shown to the public. This technology appears to be something China mastered back in the 2010s for gliders to proliferate so much within both the PLA and public space.
Fattah 2 is in an elite club then. If we attribute NK's three distinct gliders to China, then Iran is the only other nation to have shown a glider. I find it exceedingly hard to believe Iran's tech in this space is beyond the US. The US has expressed interest in fielding gliders. So cost isn't quite a barrier since they will field glider/s even as a token gesture and piece of kit. Maybe they are aiming far higher than Iran's Fattah 2? We'll have some more ability to judge this when US eventually put their glider into service and show it. I suspect they are aiming for the highest tier performance whereas Fattah 2 represents a lower tier effort but one that Iran is able to achieve.
Iran has a % of a small fraction of US MIC funding. Iran has nothing that compares to US MIC experience, industry, academic and technology access. The US basically has access to more or less the best in the world even if there's a field they do not have a lead in they could approach an ally that does. Only where it comes to China holding the lead, that may be a subset of component they can't match China in.
So how could this statement be made in good faith - "The US does not have hypersonic missiles with highly manueverable self-propelled propelled glide warheads like Iran has."
This is like saying US does not have shahed style suicide drones that Iran has. Okay the US sort of has these and certainly had higher capability equivalents well before Iran created the Shahed.
