President Donald Trump issues a public warning to Iran over its treatment of protesters, stating on social media that the United States would “come to their rescue” if authorities “violently kill peaceful protesters.” His remarks follow reports of unrest and alleged crackdowns across Iran, and they reflect ongoing tensions between Washington and Tehran. The statement raises questions about possible U.S. responses, the role of human rights in American foreign policy, and the impact of social media diplomacy on an already strained bilateral relationship.
