Look at this: http://www.iht.com/articles/2007/01/02/news/web.0102britain.php

and this: http://www.nytimes.com/2007/01/02/world/middleeast/02cnd-iraq.html?hp&ex=1167800400&en=c7d6181f15a9dae3&ei=5094&partner=homepage

"Among those most incensed by what happened to Mr. Hussein in his final moments are American officials in Baghdad and Washington, who had hoped that the execution would bring Iraqis to a point of closure over Mr. Hussein’s role in Iraq’s turbulent history"

but here's what really matters:

American officials say privately that the Maliki government, by allowing the Hussein execution to be conducted as it did, signaled more powerfully than ever before that it was unwilling or incapable of surmounting the deep sectarian divisions here.

Which means there's no prospect of pulling out any time soon.
