After the U.S. invasion of Iraq the U.S vice consul Paul Bremer tried to install a handpicked Iraqi government. The top Shia religious authority in Iraq, Grand Ajatollah Sistani, demanded a democratic vote. The issue was thereby decided. There was no way the U.S could have circumvented Sisitani‘s edict without a massive revolt by the 65% of Iraqis who are Shia and mostly follow his advice. Bremer had to fold.
