The world of Islam according to Imam Khomeini is being sought among the masses of Islamic nations rather in the Islamic governors. Considering the main problem of the Islamic nation, their dependent governors, Imam addressed the people and invited them to proceed. Imam's privilege as an intellectual and a leader is the practice of his own doctrine. In other words in the field of given doctrines, there are so many leaders and intellectuals who propose governmental algorithm and models which almost all of them just remain theoretical; but Imam Khomeini could present a sample for every nation specially Islamic nations, thus today we can see many movements which are based on Iranian Republic such as Islamic Resistance in Lebanon and Intifada.
The basic concept in Imam's doctrine is the unity preservation and preventing the division and ignorance among Islamic nation's sects and holding the cable of Islamic unity.
