Look, in geopolitics it's good to be realistic.

Is Iran, ran by hateful men, but open to trade, integration, reform, inspections and having a lot to lose perfect? Of course it fucking isn't. But realistically it's the best we could have had.

Instead we have Iran ruled by even more hateful men. Men that saw their families blown up in front of them, and have nothing to lose. The economy is already shit, and they don't care about regular people, and as we saw in the recent protests, power structures are intact and they do not hesitate using them to enforce their rule. Men who were demonstrated multiple times that American promises don't mean anything. Those men also have a pretty clear path on how they'd be left alone - Kim's nuclear weapons / threat of destroying Seoul.

How is that any better? It isn't. It's drastically worse for everyone, from the common Iranian suffering under the regime to every single one of us that will have to live under the threat of Iranian nuclear weapons and worldwide economic disruption via Hormuz and direct sabotage.
