Questions about the extent to which Iraq impacts the Iranian political scene seem to be “futile” or “ridiculous.” It's easier to talk about Iran's interference in the political choices of Iraq, the formation of the government, resolving or stirring differences among parties, or the rejection or acceptance of a certain political line. Anyway, it is unlikely that Iraq will have any effect on the current division in Iran over power, external relations, the position on the authorities of Ayatollah Ali Khamenei, or the new Iranian president.
This unilateral equation does not reflect the real balance of power between the two countries today.
