Who benefitted from the Saddam execution

While I'm thinking out loud, for which Iraqi group was the Saddam Hussein execution fiasco a bad thing? The Sunnis are now more unified. Sadr, Maliki and the Shia have scuppered the Hadley plan. Iran gets its continued chaos putting more pressure on the US to withdraw.

The only one to lose was the US.

Really, once you accept the idea that very few of these groups truly want peace at this point, Iraq makes alot more sense.

(And the US's plight looks all the more dire.)
