Mojtaba Khamenei warned that Iran will teach the United States "unforgettable lessons" if U.S. attacks on Iranian targets continue [1, 2].

The statement signals a potential escalation in military tensions between Tehran and Washington. This rhetoric follows a period of heightened instability in the region, where Iranian leadership views U.S. military actions as direct aggression [1, 2].

Khamenei, the son of Supreme Leader Ayatollah Ali Khamenei, issued the warning in a statement released from Tehran on Saturday, July 19, 2026 [1, 2]. He said that the United States' bullying will not go unanswered [1].

Recent conflicts have already resulted in casualties. Two U.S. troops died in an Iranian attack [3].

"If the United States continues its attacks, we will teach them unforgettable lessons," Khamenei said [1]. He said that Iran will make the United States regret its aggression [2].

The warning comes amid ongoing U.S. military operations against Iranian interests. Tehran has characterized these actions as aggression that necessitates a firm response [1, 2].

While some reports suggested the comments were made in person, other records indicate the warning was issued via a written statement [1].

"If the United States continues its attacks, we will teach them unforgettable lessons."

The involvement of Mojtaba Khamenei in issuing these threats suggests a strategic positioning of the Supreme Leader's son within the Iranian political and military hierarchy. By framing U.S. actions as 'bullying' and 'aggression,' Tehran is establishing a rhetorical justification for future retaliatory strikes, increasing the risk of a direct military confrontation in the Gulf region.
