You're suggesting that bombing civilian infrastructure will cause the Iranians to surrender (or to concede negotiating points in order to stop the bombing).

My point is that this doesn't work - the British under The Blitz famously had "Blitz Spirit" that was all about enduring the bombing and showing the Germans that they couldn't be beaten like this. The Vietnamese did not try to stop the bombing by surrendering or negotiating, and neither have the Ukrainians; again, if anything, they are more unified and more resolute because of the Russians attacks on their infrastructure.

Can you give me a single example where prolonged bombing of civilian infrastructure has brought a country to the negotiating table? Or made them surrender?
