Following on from that, and bringing it back to A-10s, and specifically A-10s in Iran: I doubt that there is very much that can beat an A-10 doing low passes over your city to say "We own you!"
If you are a friend of the A-10s they are a comfort. If you are not they are a constant threat.
They supply a form of coercion that cannot be matched by satellites and other unseen forces, or by any uncrewed forces, precisely because there is a person at risk inside.
And its speed and survivability make it one of the least risk options for those kinds of "show the flag" missions. Just as frigates demonstrate who owns the waves by showing the flag at sea, it is useful to demonstrate who owns the skies inland.
