Iranian rulers perceive accepting U.S. demands on uranium enrichment and missile programs as a greater threat to their regime's survival than the potential for war. Analysts suggest Tehran views appeasing Washington as a sign of weakness, which could embolden internal dissent and external pressure. Therefore, they believe taking a hard line, despite the risks of conflict, is a calculated strategy to maintain their grip on power. This stance highlights a deep-seated distrust of U.S. intentions and a commitment to national sovereignty, even at the cost of increased international tension.
