Firstly from Power Line
W]hat is not being reported is the calling for calm and cooperation by all Sunni & Shiite religious leaders (except the young Alsadar who remains a thorn). The demonstrations of national unity. The mullahs in Sunni & Shiite mosques calling for support for injured brothers and sisters, national calm. They do not report on the Shiites standing guard outside of Sunni mosques in the south. Etc...There are two sides to this incident. The side of revenge, anger and the much larger side of unity and support. This bombing in Samarah has brought more unity amongst Iraqis than any other incident since the stampede on the Kahdumiah bridge (when Felujans [mostly Sunni] donated blood for the wounded in Kahdumiah [mostly Shiite] in Baghdad). Iraqi political parties, community leaders, religious leaders, political leaders all are strongly condemning this bombing and asking for national support and help for the people of Samarah. This outpouring of compassion, support and help is what is not being reported.
Secondly, the only one who had anything to gain from this attack is al Qaeda. That they did not even claim this attack speaks volume, having learned that there is such thing as bad PR (as was after their wedding bombing in Jordan earlier). They are now operating in silence even in Jihad central.
It really is as simple as that. Not to say that Iraq will soon be a tourist paradise, but it will be more like what Afghanistan is now. The emphasis will now be on the nation building rather than national existence. The battle ground has already slowly shifted, partly eastward to Iran, and far westward to Europe.
