ICG, 7 Feb 08: Iraq's Civil War, the Sadrists and the Surge
.....Among Sadrist rank and file, impatience with the ceasefire is high and growing. They equate it with a loss of power and resources, believe the U.S. and ISCI are conspiring to weaken the movement and eagerly await Muqtada’s permission to resume the fight. The Sadrist leadership has resisted the pressure, but this may not last. Critics accuse Muqtada of passivity or worse, and he soon may conclude that the costs of his current strategy outweigh its benefits. In early February 2008, senior Sadrist officials called upon their leader not to prolong the ceasefire, due to expire later in the month.

The U.S. response – to continue attacking and arresting Sadrist militants, including some who are not militia members; arm a Shiite tribal counterforce in the south to roll back Sadrist territorial gains; and throw its lot in with
Muqtada’s nemesis, ISCI – is understandable but shortsighted. The Sadrist movement, its present difficulties aside, remains a deeply entrenched, popular mass movement of young, poor and disenfranchised Shiites. It still controls key areas of the capital, as well as several southern cities; even now, its principal strongholds are virtually unassailable. Despite intensified U.S. military operations and stepped up Iraqi involvement, it is fanciful to expect the Mahdi Army’s defeat. Instead, heightened pressure is likely to trigger both fierce Sadrist resistance in Baghdad and an escalating intra-Shiite civil war in the south.

Muqtada’s motivations aside, his decision opens the possibility of a more genuine and lasting transformation of the Sadrist movement. In the months following his announcement, he sought to rid it of its most unruly members, rebuild a more disciplined and focused militia and restore his own respectability, while promoting core demands – notably, protecting the nation’s sovereignty by opposing the occupation – through legitimate parliamentary means. The challenge is to seize the current opportunity, seek to transform Muqtada’s tactical adjustment into a longer-term strategic shift and encourage the Sadrists’ evolution toward a strictly non-violent political actor.....

Becoming an Ayatollah: The New Iraqi Politics of Moqtada al-Sadr
As a political and military force, Iraq’s Shiite Sadrist movement has undergone a number of radical transformations since 2003, when its leader, Moqtada al-Sadr, surprisingly emerged as a leading political figure. Al-Sadr’s recent decision to continue with his seminary studies and graduate as an ayatollah at the conservative seminary school of Najaf underpins a major change in the movement’s structure that could have serious repercussions for the future of Iraq. Against the backdrop of changing political alliances between Kurds and Sunnis, al-Sadr is transforming his movement into a new political phenomenon with implications for the country’s political structure and security dynamics. The consequences are also immense for Shiite Iraq, posing serious challenges to the conservative clerical establishment in Najaf.

Al-Sadr’s attempt to become an ayatollah follows his earlier call to suspend operations by his militia, the Jaish al-Mahdi (The Mahdi Army, or JaM) in the summer of 2007. Together with his decision to study in Najaf, this has marked a decisive new beginning in the organizational structure and leadership dynamics of the Mahdi militia. The decision to suspend JaM was made largely because of the outbreak of violence between Mahdi forces and the rival Badr Organization in Karbala in August 2007. The incident was a major embarrassment for al-Sadr, who had been seeking the support of Ayatollah Ali al-Sistani, Shiite Iraq’s grand cleric, and the conservative establishment in Tehran against the rebellious splinter groups within his own militia since 2005. The suspension, which came in August 2007, was a way to ensure his Shiite partners that he was willing to restructure his forces for the sake of Shiite unity at a time when US—or Israeli—forces seemed to be on the brink of starting a major military conflict with Iran.....
