Abstract
This thesis contributes to the literature on sanctions and resilience tactics through a comprehensive analysis of the sanctions imposed on Iran for over three decades. It investigates how the application of a bargaining model of sanctions successfully increased the cost of defiance for Iran, effecting enough pressure on the regime to concede to the sanctions' objectives and alter its objectionable policy, resulting in a peaceful resolution to an international dispute. It argues that the shift in sanctions narrative by the senders downplayed the role of ideology in Iran's hybrid regime, which had been historically used to reinforce the regime's counter-narrative against sanctions and maintain its legitimacy.
