Why did the US-Iran nuclear negotiation process from 2002 to 2018 fluctuate and end in a stalemate? By applying Putnam’s two-level game theory, this research demonstrates that the interactions between the international negotiators and their domestic constituents significantly impact the negotiation outcomes. For the US, the Congressional debate on the plausibility of pursuing regime change policy in Iran influenced the US negotiators and their negotiation strategy. For Iran, the gradual coalitions of the conservative power base within the governmental establishment fostered close coordination between the Iranian negotiators and their domestic constituents. From President G. W. Bush to President Trump, this case study shows the historical overview of the nuclear negotiations. Then, it explains the causes of the five specific outcomes with the concept of win-set. For each period, this research observes progress in the international negotiator’s strategy and the domestic constituents’ policy preferences and coalitions in the US and Iran. These progressions either expanded or contracted the win-set size, effectively visualizing the negotiation process and outcomes. Thus, this research highlights that dissecting the interactions between international and domestic politics is essential to understanding fluctuation in negotiation outcomes.
