There isn't even a propaganda value for the US in it though. Their Media is abusing Trump and Hegseth since yesterday at how their claims of Iran's ADs being taken out has fallen flat. The rescue of pilots is not being taken as as achievement anywhere in the US but rather as a save from fiasco that was yesterday with 2 jets shot down and 2 helicopters hardly escaping with damages. If you look at it form their shoes, they have nothing to celebrate in this all, other than having a sigh of relief that at least the pilots dragged their way back after being shot down.
As for Iran, all I have seen is Western Media speculating at what kind of air defenses Iran has suddenly unleashed on them. There was a whole article on CNN today discussing possibilities on how Iran is suddenly destroying their air superiority. That is the worry of the enemy, on top of the pilots.
Regarding the attack, this would definitely be a deterrent, not an encouragement. The US has now seen how one incident turned into a full on fiasco that took more than a day of searches, a jet shot down, putting so many assets at risk and firefights just to get a pilot back.
From all that I have read, there is no way that whatever happened since yesterday is gonna encourage them.
