Iran and the United States cut diplomatic ties shortly after Iran’s 1979 Islamic revolution and enmity to Washington has long been a rallying point for hardline supporters of Khamenei in Iran.
“This inexperienced group has not recognized the people and leaders of Iran,” he said, according to the website for state TV. “When they get hit in the mouth, at that time they’ll know what’s going on.”
Khamenei and other senior Iranian officials have ramped up their criticism of the United States in recent weeks after Trump went on an official visit last month to Saudi Arabia, Iran’s main regional rival.
During that visit, Trump singled out Iran as a key source of funding and support for militant groups. He has also criticized the nuclear deal between Iran and six major powers, including the United States, that led to the lifting of most sanctions against Iran, in return for curbs on its nuclear program. Trump has said Washington would review the deal but stopped short of pledging to scrap it.
