Iran’s Supreme Leader, Ayatollah Ali Khamenei, has issued a stern warning to the United States, threatening a severe response to any further attacks. This comes after President Donald Trump signed a preliminary peace agreement in June. According to reports, Iran deems Trump’s signature on the agreement as having no value. The statement signals heightened tensions between the two nations and suggests potential for escalating conflict. Khamenei specifically warned of an “unforgettable lesson” for the US should further aggression occur. This rhetoric underscores Iran’s firm stance against perceived provocations. The warning follows a period of increased strain over regional conflicts and nuclear policy.
