Iranian Supreme Leader Ayatollah Ali Khamenei said on Wednesday US President Donald Trump would fail in his hardened stance towards Iran, saying Tehran was stronger than during the time of the "more powerful and smarter" Ronald Reagan.
"Reagan was more powerful and smarter than Trump, and he was a better actor in making threats, and he also moved against us and they shot down our plane," Khamenei said in a speech carried on state television.
In 1988, a US warship shot down an Iranian passenger plane over the Gulf, killing all 290 aboard, in an incident which Washington said was a mistake. Tehran said it was a deliberate attack on Iran, then at war with neighbouring Iraq.
"But Reagan is gone and, according to our beliefs, he now faces God's retribution ... while Iran has made great advances in all areas since Reagan's time," Khamenei added.
"This trend will continue under the current American president and any hopes on their part that the Islamic Republic would back off or weaken is futile."
