Partisan Credibility Determines Iran Deals

When governments flip between parties and agreements are perceived as reversible, adversaries demand up‑front concessions rather than trust future administrations. That dynamic means U.S. domestic polarization (and actions like withdrawal from the JCPOA) is not a side detail but a central bargaining constraint for any long‑term Iran accord. — It reframes nuclear/regional diplomacy as partly a domestic political design problem: durable foreign agreements require mechanisms that survive partisan turnover or credible offsets to political risk.
