I’m trying to understand the logic behind U.S. Iran policy. The Trump administration withdrew from the 2015 nuclear deal because it viewed the agreement as flawed. After withdrawal, Iran expanded parts of its nuclear program beyond the deal’s limits. If the eventual solution is once again inspections, enrichment limits, and sanctions relief, how is that materially different from the framework that was abandoned? What benefits did the U.S. gain that justify the costs and risks incurred since withdrawal?
