Civil War anyone?

Blast Rocks Shiite Shrine in Samarra
One of the most revered shrines in Shiite Islam was bombed early Wednesday morning north of Baghdad, causing the collapse of its dome, police and eyewitnesses said.
The attack on the Askariya shrine, also known as the Golden Mosque, in the city of Samarra sparked immediate and widespread protests among Shiites across Iraq and reports of reprisal attacks on Sunni mosques.

I smell a setup in order to fuel and instigate a full scale civil war in Iraq. This will help us justify a very long standing army in Iraq. Does this look like a few suicide bombers? It is too big of a bombing. To me it looks like millitary grade explosives would have been placed in there.
