Don't panic over this. Negotiation is not for a deal. It is for surrender. Anyone who still thinks Trump wants to preserve this regime does not understand the situation. The only real question is whether it falls in a messy last stand or through a controlled exit. @realDonaldTrump is forcing the second one. That is not impossible. Look at the USSR. Look at Assad in Syria. The differences are many, but the similarities are enough. The need to keep a negotiation line open is obvious. When you pressure someone and leave no exit, they panic and fight till last second. When you pressure them, give them time to think, and offer a way to save themselves, enough of them choose survival. Are we supposed to forget Assad? He killed hundreds of thousands and displaced millions to stay in power. Then he ran to Russia, and Damascus fell with no resistance. The idea that “they will never surrender” does not match reality. I grew up among these people. This system is corrupt and opportunistic. It is not uniformly ideological. Ideology is a tool to brainwash the foot soldiers. and it's not even a very effective one. Have you ever seen a Shia or an Iranian blow himself up in the West, or take that kind of personal risk for this ideology? No. Never. Shias act tough only when they are in power. They can only fight the protesters with bare hands. When they are weak, they cry and play the victim. They are very different from Sunnis and Arabs in that way. The regime elite pretends to be loyal because they want their share of looting Iran’s resources. When they realize there is no share left, no future for the regime, and that China, Russia, and the rest of their patrons have abandoned them, they will beg for their lives. That moment is not too far from now. As for the brainwashed lower-rank soldiers, (unfortunately the street oppressive forces come from them) imagine they hear the truth from Trump: that Mojtaba has been dead for a long time, that the elites lied to keep power, and that those elites have already fled. All it takes is one part of the armed forces to defect or run. After that the collapse is not linear. The rest suddenly do not want to be the last people on a sinking ship. The regime is an old building that is already coming down. You do not want it to fall on the people inside. If it ends with less chaos and less bloodshed, that is better for Iranians and for everyone. Trump knows what he is doing, let's hope he succeeds.

This has already been carried out by @SecScottBessent. Modern war includes economic war, not just bombs. (Kharg is an oil island, far away from strait of Hormuz. It’s not a strategic point)
