Here is the famous Khomeini's answer to the question of "How do feel coming back to Iran?" And he replies back "Nothing" (hichi). Sadegh Ghotbzadeh who was killed a few years after the Revelation translates the question and the answer to "Nothing No Feeling, No Comment".
The Mullah gave his true opinion about Iran and Iranian people from the first day. But Iranian people specially the educated sector of the Iranian population were naive and stupid enough to follow him blindly and translate his famous comment about returning to Iran after 15 years of leaving in exile to his strength.
Maybe he was refusing to put on aires in front of a television camera.
Maybe he considered it self-promotion, to indulge in showmanship over his return to Iran.
Iranians who hate Khomeini will never consider these alternative explanations about why he said "Nothing" in response to this question, because that would spoil what they are trying to do - which is to condemn him.
