The real reason Washington wants regime change in Iran is that, in the most mass-based, genuine revolutionary upheaval in the modern history of the Muslim world, the Iranian people overthrew the brutal U.S.-imposed regime of the Shah in 1979. This deprived the U.S. of the services of the “Gendarme of the Gulf” serving U.S. oil interests, and intervening in Yemen (to support royalists against republicans) and Oman (to suppress a secessionist movement). It was a huge blow to Washington’s geopolitical interests, and the U.S. wants to reestablish its lost hegemony.
