Iranian Supreme Leader Ayatollah Ali Khamenei left a message for United States President Donald Trump on Tuesday, saying that Washington “won’t be able to destroy” Tehran, as it hasn’t been able to do so in the past 47 years. “They keep saying an aircraft carrier was sent toward Iran. An aircraft carrier is indeed a dangerous tool, but the weapon capable of sending it to the bottom of the sea is even more dangerous,” Khamenei commented during a speech. Meanwhile, a second round of nuclear negotiations between the two countries is currently underway in Geneva.
