Countries that are subject to sanctions often perceive their policies as being moral and virtuous, and they tend to view the United States as a bully attempting to dominate the world. As a result, they are unlikely to yield to the pressure of sanctions. In fact, sanctions may fuel resentment and lead to greater rebellion within the sanctioned country, further exacerbating the situation. This was clearly evident in the case of Iran, which significantly increased its uranium enrichment program after the US withdrew from the JCPOA.
