Am I hearing/reading mixed messages from Al-Sadr or what?

Muqtada al-Sadr

At the very same time that I am reading one account of fighting between Muqtada al-Sadr’s militias and U.S. and British forces intensifying, I am reading excerpts of this same seemingly and usually anti-American cleric's sermon on Friday wherein he was quoted as asking his supporters to "protect Sunnis and Christians." Keep in mind that all of this is/was (on Friday) on the eve of talks between U.S. Ambassador Ryan Crocker and an Iranian envoy about security in Iraq.

A not-so-unrelated note: I DO NOT enjoy being a "body-counter," but I do keep track and noticed that more than 100 US soldiers have died already in May -- the first time since (and including) the tragic night of Shock and Awe that we have lost more than 100 of our best for two months in a row.

When, oh when will it end??
