I think Al Sadr will get his wish of fighting to his last drop of blood:
Moqtada al-Sadr has rejected invitations to participate in a national conference and national council, and had not indicated any willingness to take part in the elections scheduled for January. Al-Sadr vowed on 09 August to fight what he called the "occupation of Al-Najaf" until the "last drop of blood" is spilled.
