Exactly. This is pure propaganda.
This phrase...
"When Moqtada al-Sadr, the young radical Shiite leader, laid siege to the Imam Ali shrine and fought U.S. Marines to a standstill in Najaf in the summer and fall of 2004..."
...proves the point.
I think a lot of the article is bologna, but I have to admit that I have not heard much out of Sistani lately and he is the one that issued the Fatwa at the begining of OIF that told Shi'ia not to oppose us and our allies. If the Shi'ia turn as a whole, life will suck there.
