WASHINGTON — Ten years and $60 billion in American taxpayer funds later, Iraq is still so unstable and broken that even its leaders question whether U.S. efforts to rebuild the war-torn nation were worth the cost.

In his final report to Congress, Special Inspector General for Iraq Reconstruction Stuart Bowen’s conclusion was all too clear: Since the invasion a decade ago this month, the U.S. has spent too much money in Iraq for too few results.

Guardian UK "Exclusive: General David Petraeus and 'dirty wars' veteran behind commando units implicated in detainee abuse"

The Pentagon sent a US veteran of the "dirty wars" in Central America to oversee sectarian police commando units in Iraq that set up secret detention and torture centres to get information from insurgents. These units conducted some of the worst acts of torture during the US occupation and accelerated the country's descent into full-scale civil war.

...Yesterday, I read how it was going to take up to $90 billion to rebuild Iraq. Bremer was shooting out numbers about how much it was going to cost to replace buildings and bridges and electricity, etc.

Listen to this little anecdote. One of my cousins works in a prominent engineering company in Baghdad- we’ll call the company H. This company is well-known for designing and building bridges all over Iraq. My cousin, a structural engineer, is a bridge freak. He spends hours talking about pillars and trusses and steel structures to anyone who’ll listen.

As May was drawing to a close, his manager told him that someone from the CPA wanted the company to estimate the building costs of replacing the New Diyala Bridge on the South East end of Baghdad. He got his team together, they went out and assessed the damage, decided it wasn’t too extensive, but it would be costly. They did the necessary tests and analyses (mumblings about soil composition and water depth, expansion joints and girders) and came up with a number they tentatively put forward- $300,000. This included new plans and designs, raw materials (quite cheap in Iraq), labor, contractors, travel expenses, etc.

Let’s pretend my cousin is a dolt. Let’s pretend he hasn’t been working with bridges for over 17 years. Let’s pretend he didn’t work on replacing at least 20 of the 133 bridges damaged during the first Gulf War. Let’s pretend he’s wrong and the cost of rebuilding this bridge is four times the number they estimated- let’s pretend it will actually cost $1,200,000. Let’s just use our imagination.

A week later, the New Diyala Bridge contract was given to an American company. This particular company estimated the cost of rebuilding the bridge would be around- brace yourselves- $50,000,000 !!
