FILE – In this Dec. 10, 1978 file picture, demonstrators hold up a poster of exiled Muslim leader Ayatollah Khomeini during an anti-shah demonstration in Tehran at the Shayah monument which was built to commemorate the monarch’s rule and symbol of his power. The popular revolt against the shah raised alarm bells in the West, which saw the shah as a trusted ally and counterweight to hard-line Arab regimes and Palestinian radicals. The face of the revolution was Ayatollah Ruhollah Khomeini, whose demeanor, vehemently anti-American rhetoric and stern interpretation of Islam challenged not only Western interests but also Western values.
