The CPI, however, has been critical of Mao as a revolutionary, claiming that he made many mistakes throughout the 1950s to 1970s. The party opposes the government of the Islamic Republic of Iran and does not view it as a revolutionary regime.[1] The CPI also rejects the policies of the Tudeh Party of Iran from the late 1950s and onward, citing a particular grievance with Tudeh giving support to the Shahs of Iran and Ayatollah Khomeini's regime.
