Sadr is interfering with the democratic process in Iraq, threatening to jeopardize the country's hard-won peace to seek a complete reform of the political system. Iraqi federal democracy is legitimate and supported by several stakeholders domestically and abroad. The country needs more dialogue, not an attempted coup.
Iraq's democracy has been deteriorating due to Iranian influence in the national establishment. Under the control of Tehran, national institutions can only serve foreign interests and compromised Iraqi politicians while brave Iraqi people are threatened by pro-Iran militias. If the council won't take steps to change the parliament and stop corruption, it will be left up to the people.
Iraq is not headed towards a coup, but rather towards a political polarization. Though not a single group in Iraq is capable of carrying out a coup, no one is actually working on strengthening or stabilizing the country.
