Iran's Supreme Leader Ayatollah Ali Khamenei has issued a strong rebuke, stating that Iran "will not yield to the enemy" and warning that "rioters must be put in their place." This defiance comes in direct response to threats from former US President Donald Trump, who recently posted on Truth Social that the United States would intervene if Iran "shoots and violently kills peaceful protesters." Trump further amplified pressure by announcing a 25% tariff on countries trading with Iran. The statements are set against a backdrop of widespread and escalating protests across Iran, which began around December 28, 2025. Initially sparked by economic grievances and a significant devaluation of the Iranian rial, the demonstrations have quickly broadened to include calls for political change and represent the most serious challenge to the Islamic Republic in years. Reports indicate that these protests have spread across all 31 provinces, leading to violent confrontations with security forces, numerous arrests, and dozens of deaths. International monitoring groups have reported severe internet restrictions and blackouts across the country, making independent verification difficult but highlighting the government's efforts to control information. Khamenei acknowledged legitimate economic concerns driving some protests but drew a clear distinction, condemning "saboteurs" and those acting on behalf of foreign enemies. Meanwhile, India has issued a travel advisory urging its citizens to avoid non-essential travel to Iran due to the volatile situation. The intensifying rhetoric between Tehran and Washington, coupled with the ongoing domestic unrest, underscores a critical geopolitical flashpoint with potential regional and global implications.
