I was on a few Russian news websites today reading the comments about the news coming out of Iran.
Russian people are watching closely because while not to the extent of Iranian oppression, there is a growing discontent with the Putin regime...However there is an even greater aversion to all things “revolution” related. Nobody wants that.
One Russian commentator noted that the Iranian situation is a reminder of how a revolution is pointless when it generates chaos, is without a unified platform, or a visible leader to rally around, etc...

ROLFMAO!
And back to the topic in order to answer the question would Russia help or not you should start with the question what US wants from Russia.
Second I don’t see some adequate response from US on developing situation too and I also think Russian leverage over Iran is overestimated. Iran is not a Russian puppet.
Last but not least you shouldn’t take cooperation for granted. Russia is under US sanctions along with Iran itself. You want to play a zero sum game on their interest but expect their support for your bets. It’s not how foreign politics work.
Overall I believe Russia is interested in freer Iran unless it would be someone’s puppet.
