The Iraqi leader needs to show he's in control...and this also refers to what Bush meant by saying that the US doesn't have unlimited patience...
it also means that the Iraqi leader ( 5 months on the job ) still has lots of work to do to get the Iraqi armed forces in shape to handle the security ofthe country.
The US moved in on the territory of the Shiitemonkey cleric ( Iraqi leader's buddy )...and nobody phoned him...

...ya huh...I wonder why?
The leader of Iraq knows what he needs to do and needs time to do it in, he refers to setting timetables and this is probably the basis of the unsettled comments from him.
Iraq needs to worry also about Iran and Syria once the majority of US troops leave...( there should be a US base there forever )
I think it was a good move on the US commanders part. Shake that monkey cleric outta the tree ! send him back to Iran. ( he wears the black turban as the Taliban, same religious extremist followers, as does the weenie cleric in Hezbolanon.)
