I am fully aware of the 'settlement', but it was essentially a temporary lease on a nuclear program, not a permanent solution, and it deliberately ignored the most dangerous aspects of Iran's behavior, it was deeply flawed. The IAEA confirmed compliance with the narrow technical rules of the JCPOA, but that doesn't make the deal a strategic success. First, the Sunset Clauses meant that by 2030, Iran would have been legally allowed to enrich uranium at an industrial scale—the deal just kicked the can down the road. Second, the negotiation deliberately ignored Iran's ballistic missile program and its regional proxies. While the West unfroze billions for Tehran, that money flowed directly to the IRGC, Houthis and Hezbollah, destabilizing the region, as there were zero condition on how it was spent. Finally, a deal that doesn't account for the delivery systems (missiles) or the regional aggression (proxies) isn't a 'settlement'—it’s a tactical retreat. True negotiation requires both sides to agree on a total framework of peace, not just a temporary pause on one specific lab while the rest of the war machine keeps grinding. Obama and Kerry thought a flawed deal that stopped a nuke was better than a no deal. They believed they could handle the proxies and missiles separately thru sanctions, well that didn't work out to good! In reality Iran used the 'nuclear peace' years to build the most sophisticated ballistic missiles and drones in the ME.
