جمهورية إسلامية
Mohammad Khatami is a strong advocate of "Islamic republic". In a speech on 11 October 2009, he warned that oppression of his allies and reformists will lead to emergence of those who are against Islamic republic constitution. He said "unfortunately we are witnessing the emergence of nuclei that negate the very basis of the Islamic republic." Khatami however respects the opinion of people strongly and yet believes that the optimum form of government differ for each nation and cannot be copied from the west.
