The source for the Iraqi calls for a US withdrawal timetable?

Add this little bit to your Iraqi political factoring,

A strong political debate is being waged in Baghdad on the role the Shiite supreme religious authority in Najaf, Grand Ayatollah Ali Al Sistani, played in negotiations between Iraq and the US on a memorandum of security.

Al Sistani insisted on including a timetable for the withdrawal of American forces.

Being painted as Sistani calling for nationalism, but neither domestic politics nor Sistani's long ties to Iran should be discounted.
