Europe’s attitude towards Iran, particularly with respect to the 2015 nuclear deal (the JCPOA) and related ballistic issues, is hard to understand. A collective desire to defy the US, which pulled out of the JCPOA in May and re-imposed tough sanctions on Tehran, can’t be the cardinal reason. It is more likely that the EU states are succumbing to a sophisticated blackmail campaign directed by the Iranian regime aimed at preserving the JCPOA and deepening existing cleavages among the transatlantic partners.
