Al Queda sees a weakness and is doing the rightthing to exploit that weakness. Reports from Iraq indicate America and GWB are much loved.
Al Queda will not prevail. they will be anniaiated by the Iraqui's.
The Iraqi's are in a position to see people who stand out like a sore thumb in their country. If it is Al Queda, they will face the same problem as Uday and Qusay did with informers.
This is especially true if water mains etc. continue to be targeted. Even if it isn't Al Queda, the Iraqui's will be looking for anyone capable of causing the problem. Water is almost worth more them than oil is right now.
