Israel never received top assets such as F-22 or B-2 or any Black Project asset created by DARPA/Skunkworks/black project company.
To my knowledge the zionist regime didn't make a request for those assets and in terms of military hardware hadn't had any request turned down by Washington so far.
So Russia not giving ToT of SU-35 makes sense as it would be the equivalent of US giving ToT of F-14 back then.
I was simply responding to the claim that Russia will "not offer Iran any sort of ToT, even for a bolt" (and similar statements suggestive of a western-apologetic / pro-western mindset). That is simply counterfactual. I wasn't commenting on the Su-35, ToT for which is less likely.
I think the real negative is Russian unreliability in arms deals dating back to 1990’s. Outside of the desperate fire sale of arms to anyone with cash after fall of Soviet Union, Russia fell into Western trance of trying to be a pseudo Western country until they realized the West would never treat them as such.
Most of Iran’s reverse engineer is due to Iranian ingenuity not Russian assistance. That is not to say there has been NO Russian assistance. There certainly has, but if it was any other banana country they would have gotten a lot more Russian assistance.
Case in point, Baboon Arabia....China has helped them with build missiles. Build solid fuel production plants. The list goes on. Meanwhile, our last major China project was C-802 which we all know how much “help” China was in that regard. Since then we have used them mostly for raw materials and certain parts for radars and Missile program.
You can decide for yourself who is more friendlier to Iran...China or Russia. But both of them seem to treat Iran’s adversaries a whole lot better than they treat Iran.
At the end of the day, all one needs to keep in mind is that the US and zionist regimes are existential enemies not just to the Islamic Republic but to Iran as a nation and civilization, while Russia and China are partners no matter their record in this regard. This alone should suffice to neutralize the russophobic / sinophobic propaganda spread by the exiled opposition as well as by reformists and moderates inside Iran, whose actual goal is to challenge the Islamic Republic's principled anti-imperialist stance, to trade the policy of Resistance initiated in 1979 for renewed vassalage to the zionists and Americans.
Russian military cooperation with Iran has been notable and includes a considerable list of items. In fact a thread dedicated to the subject would surely be eye-opening, as it would probably lead to a revision of certain misconceptions long held by many. Apart from the UAE's expected purchase of the Su-75, I can't think of a particularly noteworthy defence contract between Russia and the PGCC regimes. All in all, one can't say Moscow treated them a lot better than Iran when it comes to arms deals.
As for China, technological cooperation benefiting Iran's domestic arms industries is more than likely. It was recalled here with regards to the Kowsar's highly advanced radar, and it wouldn't surprise me if Iranian engineers learnt a thing or two from Chinese colleagues that came in handy for the development of the advanced domestic air defence solutions unveiled by Iran. This is just as valuable as anything China supplied to Saudi Arabia. The thing is though, that none of it has been officially acknowledged by either side, for obvious reasons.
Beijing is highly concerned about the prospect of a war in the Persian Gulf jeopardizing its energy supplies, and more generally about any instability or armed conflict along the Eurasian landmass and adjacent sea routes because China's prosperity and development model are still founded to a considerable degree on trade. Moreover, impartiality and doing business with as many parties as possible irregardless of antagonisms between them, tends to be a Chinese principle of foreign policy.
Keeping intact the balance of power in a given region might imply extending additional support to the comparatively weaker side. In the Persian Gulf, this translates into China signing a greater number of overt arms deals with PGCC states because the latter are lacking Iran's indigenous technological and industrial capabilities. This does not mean Beijing wants to help them overpower Iran, but that they need more support for the balance of power to be maintained which, so China believes, will contribute to averting the outbreak of a major armed conflict between the Iran and the PGCC.
Russians and Chinese are dealing with an Iran that has reached impressive levels of self-sufficiency in the defence industry and other sectors. Prior to the Islamic Revolution however, the US regime was arming at highly overpriced rates an Iran incapable of producing anything beyond rifles and ammunition - and making sure to perpetuate Iran's state of structural dependency. Case in point, how Iranian personnel were barred from participating in the maintenance of some of the equipment purchased from the USA, even though they were proficient enough to do so. It's logical for major powers to put limits on what they're ready to offer to fiercely independent nations with a strong and advanced defence industry.
At any rate, I was responding to the claim that Russia won't offer no ToT at all to Iran, which is contradicted by documented facts. I wasn't suggesting that Russian or Chinese assistance has played a greater role than domestic efforts in advancing Iran's defence industry.
