No, what I'm saying is Iraq has oil money, Syria does not(atleast not significantly and b/c the US took over the Oil fields and gave it to the PKK).
Russia also does not have US money to give donations(which again, the US didn't donate the strategic weapons to Iraq, they sold them on an open market, a market in which Iraq also purchased from Russia)
Russia also felt there wasn't a need to give free weapons, and they thought the war was over and also, as I mentioned the Israel thing.
The Russians even when someone like Iran was willing to buy S-300s delayed transfer of S-300s and refused other sales to Iran. the dynamics around that only recently changed for Iran post Ukraine invasion when Russia needed help with Drones. Before that Russians were more than Accommodating towards Israel. Even China has been hesitant, they refused sales of J-10s to Iran, citing Israel and Saudi relations.
Iran learned the hard way that the only way for them to get weapons were to build themselves or to get them from Sanctioned states like North Korea and Libya in the case of ballistic missile tech.
