A new political bloc is forming in Iran, comprised primarily of relative moderates and reformists seeking to reassert their political influence in the regime. This bloc includes prominent Iranian politicians, such as former President Hassan Rouhani and former Parliament Speaker Ali Larijani, who have become increasingly marginalized in the political establishment in recent years. This bloc could complicate the intra-regime struggle to determine who will succeed the supreme leader when he leaves the scene. On this episode of Overwatch, ISW Research Director Matt McInnis sits down with Iran analysts Nicholas Carl and Kitaneh Fitzpatrick from the Critical Threats Project to discuss this emerging bloc and what it might mean for US-Iran relations.
