Russia has consistently been cold toward Iran.
While it was willing to sell S-400s to Turkey, which is eager to attack Russia in various areas, it finally sold only four S-300s to Iran after a dispute in the International Court of Justice.
There is no way that Russia would ever sell Su-35S to Iran, and the Iranian government has clearly been deceived from the very beginning.
There is no other way but to abandon the illusion and take the path of self-sufficiency.
