I don't know. If your enemy threatens you with destroying your energy infrastructure on a weekly basis, has already imposed a naval blockade on your country and doesn't want to lift it even temporarily for you to save face and sign a bad deal, it seems to me that you haven't established deterrence.
If anything, you have lost your remaining deterrence as well.
There is no total Iranian victory in this war. Iran lost her hard-earned victory the moment it accepted an early ceasefire and decided to negotiate with the Americans. You do not negotiate with people who have proven twice in the last 10 months that they do not intend to negotiate with you and want to subdue you.
The Americans asked for a 45-day ceasefire. Remember? Iran accepted a 2-week ceasefire only to save face. Guess what? The Americans are going to get their 45-day ceasefire anyway, while passively hurting our country. Another defeat for us, another victory for the Americans.
