Emphasising the centrality of domestic politics in decision-making on both sides, Hurst adopts a broader perspective on the Iranian nuclear programme and explains the continued failure of the USA to halt it. He reveals how President Obama's alterations to the American strategy, accompanied by shifts in Iranian domestic politics, finally brought about a resolution.
