Khamenei spoke at the sermon of Eid-ul-Fitr, which marks the end of the Islamic holy month of Ramadan.
"The Great Satan (the US), with all its efforts and temptations, has not achieved its goal in this region... the US is on its knees," he was quoted as saying by Efe news.
Khamenei pointed out that "Satanic powers" wanted Iranians to lose hope by imposing "economic pressures".
He stressed that "despite the propaganda of the enemies, Muslim nations have come closer to Iran. These enemies, of course, try and are always defeated".
US President Donald Trump announced in May Washington's withdrawal from the 2015 pact between Iran and six world powers to limit Tehran's nuclear activities.
