He made the remarks in an address to a meeting with students from across the country ahead of national Student Day and the National Day of Fight against Global Arrogance celebrated on Nov. 4 to mark the Iranian people's takeover of the US Embassy in Tehran less than a year after the victory of the 1979 Islamic Revolution.

"Some think that the United States is an untouchable power, but if we take a look at the events that unfolded on this day (in history), it turns out that no, it is completely vulnerable," Khamenei told the students.

The historic day full of lessons for the Iranian nation manifests US "wickedness and suffering blows," he noted.

Washington claims that the starting point for its hostility toward the Iranian nation was the takeover of its embassy in Tehran, "which is a lie," Khamenei said.

The disputes and differences between Iran and the United States began on Aug. 19, 1953, the day when the Americans staged a coup against the government of then Iranian Prime Minister Mohammad Mosaddegh who had nationalized the country's oil industry in March 1951, he added.
