It's another fascinating development:
Iraq's most influential Shiite cleric has been quietly issuing religious edicts declaring that armed resistance against U.S.-led foreign troops is permissible a potentially significant shift by a key supporter of the Washington-backed government in Baghdad...
But unlike al-Sadr's anti-American broadsides the Iranian-born al-Sistani has displayed extreme caution with anything that could imperil the Shiite-dominated government of.
The two met Thursday at the elderly cleric's base in the city of Najaf south of Baghdad.
If Maliki continues to isolate Sadr and Sistani backs him, we could have a moment when a Shiite government in Baghdad asks the US to leave. Then what will Bush do? Or McCain?
