Iran’s supreme leader warns US that joining Israeli strikes will ‘result in irreparable damage for them’ Iran’s supreme leader has warned the United States that joining the Israeli strikes targeting the Islamic Republic will “result in irreparable damage for them.” The comments by 86-year-old Supreme Leader Ayatollah Ali Khamenei came in a statement read out by a state television anchor against a still image of the leader. “Any military involvement by the U.S. in this field will undoubtedly result in irreparable damage for them,” the statement said. In the message, Khamenei also urged officials to “continue their work with strength and trust in God.” “God will certainly and surely make the Iranian nation … victorious,” he said. State television said that a video of Khamenei giving the same address would be aired later.
