they absolutely would have.... there wasn't a single line they didn't cross in that war. even if they didn't directly hand them out to 'vetted' Syrians. if there was an Iranian air force presence making a decisive difference. at the very least there would have been CIA agents/ American/Zionist special forces operating them.
they would not have allowed t he Iranian air force to operate with impunity like they did the Russian airforce.
and to say that Russia would take a huge geopolitical risk like this on the word of a foreign general is severely underestimating putin.
Russia was observing this war from day 1. Saw how they got duped in Libya by giving the west a UN mandate to attack. For them at first it was blocking any UN attempts. They had all but given up on assad

Then came Iranian involvement. building up the government militia force NDF to take huge pressure off the SAA and prevent their collapse. Balance the books of the Syrian government to keep them in the figtht. providing advisors that changed Syrian tactics from throwing men into meatgrinders in city combat that was destroying the SAA. To siege warfare tactics that saved men and stabilized the situation. then Hezbollah came in and started wiping out the terroists presence around the Lebanese borders.. and more militias like the fatemyouun and more IRGC advisors and assad was making sstead gains everywhere and became a viable choice once more.
that's when the west and aranbs went full retard and started openly giving out serious military equipment and Turkish forces were rumoured to be directly assisting their terrorist proxies. that's when bashard started losing ground once more and the Russians entered.
without the Russians I doubt bashar would have lost decisively either. he probably would have had to withdraw from the east completely and set up a defensible shield around the west with Iranian,hezbollah and a friendly population. its highly doubtful they would have been able to finish assad off. this was always the Iranian "plan b" people were speculating on.
Now in this sort of back and forth environment. do you seriously believe if iran had escalated again and sent its entire air force to assist assad. do you really think the Iranian enemies would have sat idle and accepted defeat? or would have escalated themselves by shipping in anti-air systems or directly engaging. there is no question in my mind about this and we can agree to disagree on it
