What's my take on this. Apologies in advance, since I'm not a fluent Cuck-lish native speaker
First of all, I'm not totally sure about this idea that Iran doesn't want weapons from you know who.
We need to look back to 1990s, when even a soft, pro-Billy wuss called Yeltsin was able to sell 3 standard Kilo class SSK to Iran. Furthermore, AFAIK Yeltsin also supplied Iran with T-72 MBT and during 1990s that was considered to be quite modern.
Even today, those (now old) 3 standard Kilos (I think there has been some attempt from Iran to modernize them) are the most capable units that exist in the Iranian Navy which is mostly non-existent.
Also, AFAIK, Yeltsin did sell av few MiG-29 to Iran. Wasn't much to talk about, but still, there were about 12 og 14 MiG-29.
What's interesting is that Kilos and MiG-29 can both be a defensive and a offensive weapon. But SAMs are defensive only. So Russia under Putin (and Medvedev) have hesitated far too long to sell S-300PMU2 to Iran. By the time they did so, Israel already had F-35 and other weapons systems that they practiced to attack S-300 versions that belong to Greece.
As per today, I cannot think of one platform that Russia (Putin / Medvedev) has sold to Iran that can be used in offense, and not defense only. We all know that there were lots of rumors about Su-35 being sold to Iran (those that were built for Egypt), but it looks like several of those Su-35 are now in Algeria.
Sure, there can be lots of arrogance in Iran regarding their former "historical prime", and they might have gotten high in 2006 when Hezbollah was able to stand its ground against Israel in Lebanon, so Iran might have thought that "Hezbollah-style" paramilitary is the way to go. But I am not sure about it as Iran was at times very pissed at Russia for not getting S-300 when Iran was expecting to receive them.
As I remember correctly, Iran actually sued Russia (Medvedev) for 4 billion USD.
As you can see from the link, Iran ordered S-300 systems in 2007, but they didn't receive them until the end of 2016. By that time, they were already half-old against Israel and the U.S. And now, in June 2025, a handful of those systems don't stand a chance.
Basically look at Libya og Syria. Libya ordered weapons from Russia in 2010, but before they were able to receive them, they got brutally massacred by NATO. At the same time, Libya gave up its nuclear program a few years before that. So basically, Libya was in the worst position ever - no nuclear program going on in order to protect itself, neither did they have modern, conventional weapons.
Syria was forced to give up their own (poor man's) WMD gas, and once Syria did so, they were actually done for that day. As we see the result today. Totally destroyed and not able to use WMD gas as an mass attack against advancing, extremist paramilitaries and terrorists. Needless to say, Russia was also supposed to sell more modern systems to Syria, but it never happened.
Iraq, Libya and Syria (just like Yemen now, not to mention Somalia, Sudan, South Sudan) are chopped up in several territorial pieces.
The only country that was brutalized, but still managed to win and keep the whole territory intact, is Taliban in Afghanistan.
And even better: the country that managed to avoid being brutalized directly at least (besides sanctions) is the forward-thinking North Korea. They knew and they were smart to get the nukes as soon as possible. And you can see now, North Korea is smart again by directly sending forces to Russia, whilst Iran only send a few missiles and drones. That is a big difference in a sense of the fact that North Korea is willing to die for Russia, but at the same time, North Korea will have clear expectations to get things they need back from Russia, such as assistance in other weapons programs, oil and gas supplies, etc. North Korea isn't playing around, they want stuff right away. And its very good to see clear results in regards to the North Korean Navy with new destroyers, new submarines being built that far surpass anything Iran has. The same goes for North Korean long-range missiles, well ahead of Iran despite being poorer than Iran.
Iran has done mistakes in being naive and easy to manipulate by the U.S. Everyone who believed in the brutal U.S. regime will always be conned at the end. Iran signed the deal in 2015, but the Trump regime shredded the deal in 2018.
The U.S. regime is not agreement capable. It is designed to destroy and maintain brutalism at the highest core. At the same time, Russia has been also dragging its feet in order to deliver what Iran wanted at any point of time.
So, yeah, whilst Iran can be high on their former glory, I don't think they will be that high anymore as they have seen that their airspace is being penetrated brutally from all directions. But again, at the same time, will Russia play games again or not? Hoping to get concessions on Ukraine and their drag their feet regarding Iran again. That is if current Iran survives at all. That's a big "IF".
