Mr. al-Assadi said he does not foresee any change in an existing ban on senior officials of the Sadrist Movement from meeting with U.S. or British officials.
Once a fierce sectarian defender of Iraq’s Shiite majority, Mr. al-Sadr has expanded his reach in recent years, reaching out to Sunnis, Christians and other minorities. After telling his followers to protect Christians, young men from Mr. Sadr’s stronghold in the mostly Shiite neighborhood of Baghdad’s Sadr City began wearing large crosses around their necks in a sign of solidarity. In a previous election, the Sadrists formed an alliance with the Communist Party, which is officially atheist.
Externally, he has fostered relations with Saudi Arabia and the United Arab Emirates at a time when those countries’ Sunni Arab rulers were hostile to Iraq’s Shiite-led government. Domestically, one of his main demands is to clean up Iraq’s dysfunctional and deeply corrupt political system, which appoints people to senior government posts on the basis of party loyalty rather than competence.
“He has grown and evolved,” said Nabeel Khoury, a former U.S. State Department official who served in Iraq in 2003. “But I think to some extent we underestimated him in the very beginning.”
Mr. Khoury said that he was approached in 2003 by Mr. al-Sadr’s aides as Iraq’s first governing council was being decided.
“We had coffee, we talked and they said Sadr was interested in playing a political role,” said Mr. Khoury, a fellow at the Atlantic Council. But Iraqi political figures who had returned from exile did not want Mr. al-Sadr involved, Mr. Khoury said, and the United States followed their counsel.
A few months later, the cleric formed his Mahdi Army militia to fight occupying troops.
When U.S. forces had an opportunity to kill Mr. al-Sadr during a battle in Najaf, Washington told them to stand down, also on the advice of the Iraqi expatriate politicians, said Mr. Khoury, adding: “They knew if Sadr was killed it would become a big problem for them.”
