TEHRAN -- Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei here Saturday warned the United States and Israel that they will definitely receive a crushing response for their atrocities.
“The enemies, both the U.S. and the Zionist regime, should know that they will definitely receive a teeth-breaking response for what they are doing against Iran and the resistance front,” he said in a meeting with students.
Iranian officials have pledged to avenge Israel’s act of aggression targeting two Iranian border cities, Ilam and Khuzestan, as well as central Tehran in the early hours of October 26.
“This is not merely a matter of revenge but a logical action—an approach aligned with religion, ethics, and the Sharia, in accordance with international regulations,” Ayatollah Khamenei said.
The Leader made the statements during the occasion to mark the U.S. embassy takeover by Iranian students on November 4, 1979, known as the National Day of the Fight against Global Arrogance.
“We are certainly doing everything necessary to prepare the Iranian nation to stand against arrogance, whether in terms of military readiness, armaments, or political actions, and thank God, our officials are currently engaged in this,” the Leader said.
The overall movement of the Iranian people and the country’s officials, he said, is “definitely and justly aimed at confronting global arrogance and the criminal apparatus that rules today’s world order”. 
“Rest assured, there will be no negligence in this regard,” he said. “The Iranian people and the country’s officials will not hesitate or neglect this course. Rest assured.”
He also referenced the U.S. embassy takeover, saying it was not merely a site for diplomatic and intelligence activity, but rather the headquarters of
 plotting to destroy the Islamic Revolution.
Iranian students took over the embassy in Tehran, also known in Iran as the “Den of Espionage,” less than a year after the Islamic Revolution toppled the U.S.-backed Pahlavi dictatorship in 1979.  
Every year on the 13th day of the Iranian month of Aban, the Iranian nation, particularly the students, commemorate the event by staging rallies across the country, calling on all Muslims and freedom-seeking nations to resist against arrogant powers and not to succumb to their bullying.
“For the Iranian nation, inspired by Islamic teachings, standing up against oppression is a duty. Confronting arrogance is a duty. Arrogance means comprehensive economic, military, and cultural domination and the humiliation of nations,” Ayatollah Khamenei noted.
The Leader emphasized that the Iranian nation’s rational, wise, and logical movement, aligned with human, Islamic, and international principles in confronting arrogance, must continue.
“The continuation of the Iranian nation’s path in confronting arrogance requires knowledge, thought, technology, and a roadmap,” the Leader said.
Ayatollah Khamenei also touched on longstanding U.S. enmities toward the Iranian nation.
“The effort of historians who distort facts is to claim that the conflict between Iran and the United States began on November 4, 1979. This is a lie. The Americans clashed with the Iranian nation from the very start of the Revolution, even from years before, doing everything they could against Iranian nation,” he said.
“American involvement and efforts in Iran were extensive, even before August 19, 1953,” he said, referring to a CIA-orchestrated coup in Iran that overthrew the democratically elected government of Dr. Muhammad Mosaddeq.
“However, the clearest evidence was on August 19. A national, popular government was in power in Iran, but the Americans entered the field, betraying the trust of a government that had naively trusted them. They overthrew that government and established the oppressive rule of the Shah. For many years, the Iranian nation directly experienced America’s enmity.”
The Leader said the Americans staged a coup in Iran, set up SAVAK in the 1950s, and established a center of torture and pressure on fighters and freedom-seekers. 
So many young people, faithful individuals, and freedom-lovers were either killed, mutilated, or tortured by SAVAK’s criminal agents—the so-called Shah’s intelligence agency, he added.
SAVAK was established in 1957 with the assistance of America’s CIA and Israel’s Mossad. The agency was vested with far-ranging powers to use torture against those who expressed dissent against the West-backed Pahlavi regime.
