its not a question of a section of the population and politicians not
'supporting the troops' -
the troops no matter how professional were doomed from the start.
There werent enough of them to provide security. At least a 100,000 more were required.
And those that were present stood by while hospitals and important public services like water filtration facilities were looted and destroyed.
NOT their fault - it was incompetent planning , arrogance, overconfidence. What does one expect from a president who didnt know there was a difference between Sunni and Shiite 3months before the invasion?

And the incompetence continued.. billions of Iraq funds earmarked for reconstruction unaccounted for, much of it went to corrupt US contractors (eg. instead of replacing water filtration pipes they simply polish them and charge half a million).

the best comment came from Michael Fleischer who got his CPA job through his brother Ari Fleischer - who said without apparent irony
"we'll be teaching the IRaqis how to conduct business as in America, all they know is cronyism"

of course most of the people that went to work for the CPA werent hired for Middle East experience they were hired on the basis of loyalty. Kids whose only experience was driving an icecream cart - got jobs distributing millions for Iraqi reconstruction - only cause they posted their resumes on conservative websites.

by the way the US didnot go in for oil, at least not directly.
but a non-opec oil nation with reserves the size of Iraq could dump lots of oil on the market and thus make OPEC irrelevant. that would be good for the US, although one wonders if the money spent on the Iraq war and the estimated cost ($2-3trillion) to the US were better spent on energy independence.

Adding 20,000 troops will not make any difference now. (Its doubtful that even a 100,000 would.) Iraq will split up into two or possibly 3 states but it wont be the end of the world.

Bushs lectures to the Maliki govt are almost comical. As if the Maliki govt could do something, if it wanted to. Most of the army (at least the ones not on paper only) are Shia. Shia and Sunni will not serve together. Sadr has his 60,000 militia which hes not about to disband.
And most of the trained professional class have left long ago.
