Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei says the top world powers have opposed the Islamic Republic since its inception but have failed to achieve any of their objectives.

“Since the first day of the [1979] Revolution until today, the number one materialistic powers in the world have stood against the Islamic establishment but have failed to make any headway in this regard,” the Leader said in a meeting with the commanders and staff of the Islamic Republic of Iran Air Force on Monday.

Ayatollah Khamenei further urged Iranian officials to be alert as to the plots against the country. "Remain vigilant about what lies behind enemy smiles," the Leader said.
