I hope so, Aus. I remember when I first joined FM, I did a lot of research into the Shia and Sunni, and there have been times when the two divisions of Islam did live and work together. If, by attacking Iraq, the US messed that up, so be it.
There is progress being made, if you read the n e w s r e a l s l o w. This is from yesterday's Seattle Times:
Qadisiyah had been the scene of fighting among Shiite factions, and U.S. and Iraqi troops conducted a big operation there last year. The handover was delayed from last month.
U.S. forces also have delayed the handover of Anbar province, the sprawling region west of Baghdad where occasional bombings and combat occur despite a sharp drop in violence. Anbar had been a stronghold of al-Qaida in Iraq and other extremist groups until Sunni tribes turned on them and allied with the United States.
The government of Iraq seems to be working together and is possibly growing stronger because of it. We'll see.
