It seems clear to me from what Trump and JD Vance have said that the reason negotiations failed was the nuclear enrichment factor. Iran has agreed to 5 years while the U.S wants 20 years of non-enrichment. Basically, Trump wants a JCPOA 2.0 with his own stamp on it. It seems to me like a deal can be made soon. Maybe for 10 years. Now I might not be politically well-informed, so maybe someone here can enlighten me on how that's gonna lead to regime change.
