I'm certain most of Iran's attacks on US forces are using Russian supplied or engineered components as well.
So unless you would like to hold Russia to the same standard regarding Iran, this is all just Russian propaganda.
There’s one crucial difference in your analysis. Russia never went within 1,000 miles of saying they wouldn’t supply Iran. But NATO has said, repeatedly, they will not engage with Russia militarily and they won’t allow their equipment to be used to attack Russia.
I’m not saying that mean there’s anything wrong with any particular bombing. I am saying NATO is being hypocritical and Russia is not.
