• The IRGC is also the backbone of the clerical establishment in Iran. The senior cadres of the IRGC and the Supreme Leader Ayatollah Ali Khamenei enjoy the final say in Iran's domestic and foreign policy and support for proxies. The IRGC, in addition, is engaged in the domestic repression of dissidents; the suppression of freedom of speech, press and assembly, and imprisoning political opponents. The Washington office of an Iranian opposition group, the National Council of Resistance of Iran (NCRI), has released a 175-page book, "The Rise of the Revolutionary Guards Corps Financial Empire," demonstrating that the IRGC controls more than half Iran's GDP and owns several major economic powerhouses and religious endowments, such as Astan-e Qods Razavi, in the northeastern city of Mashad. The NCRI also published another detailed book on 15 Iranian terrorist training centers, where the IRGC provides ideological, military and tactical training to foreign recruits, who are later dispatched to conduct terrorist activities in the Middle East and beyond.

The establishment of an Islamic State where the Jurisconsult (Faqih) would hold ultimate authority, 4. The Faqih would be legitimized through popular vote, 5. The Faqih would have the authority to interpret and enforce Islamic law in all aspect of society, 6. Social justice, equity and the welfare of the people would be implemented, 7. Resistance against oppression both from within and outside the country would be a duty, 8. Islamic jurisprudence would evolve and adapt to the changing times.
