Anti-American sentiment in Iran is not new; the chant "Death to America" has been in use in Iran since at least the Islamic revolution in 1979, along with other phrases often represented as anti-American. A 1953 coup which involved the CIA was cited as a grievance. State-sponsored murals characterised as anti-American dot the streets of Tehran. It has been suggested that under Ayatollah Khomeini anti-Americanism was little more than a way to distinguish between domestic supporters and detractors, and even the phrase "Great Satan" which has previously been associated with anti-Americanism, appears to now signify either the United States or the United Kingdom.
