The Bush Administration was wrong about the benefits of the war and it was wrong about the costs of the war. The president and his advisers expected a quick, inexpensive conflict. Instead, we have a war that is costing more than anyone could have imagined.

The cost of direct US military operations - not even including long-term costs such as taking care of wounded veterans - already exceeds the cost of the 12-year war in Vietnam and is more than double the cost of the Korean War.

More than one million Iraqis have died because of the war in Iraq since the US-led invasion of the country in 2003, according to a study published Wednesday.

A fifth of Iraqi households lost at least one family member between March 2003 and August 2007 due to the conflict, said data compiled by London-based Opinion Research Business (ORB) and its research partner in Iraq, the Independent Institute for Administration and Civil Society Studies (IIACSS).

The study based its findings on survey work involving the face-to-face questioning of 2,414 Iraqi adults aged 18 or above, and the last complete census in Iraq in 1997, which indicated a total of 4.05 million households.

The largest dam in Iraq is at risk of an imminent collapse that could unleash a 20m (65ft) wave of water on Mosul, a city of 1.7m people, the US has warned. A $27m US-funded reconstruction project to help shore up the dam has made little or no progress.

“In terms of internal erosion potential of the foundation, Mosul Dam is the most dangerous dam in the world,” the corps warned, according to the SIGIR report. “If a small problem [at] Mosul Dam occurs, failure is likely.”

If that were to happen some have predicted that as many as 500,000 people could be killed.

President George Bush will have spent more than $1 trillion on military adventures by the time he leaves office at the end of next year, more than the entire amount spent on the Korean and Vietnam wars combined.

There are also disturbing signs that Mr Bush is preparing an attack on Iran during his remaining months in office. He has demanded $46bn (£22.5bn) emergency funds from Congress by Christmas and included with it a single sentence requesting money to upgrade the B-2 “stealth” bomber.

In the week in which General Patraeus reports back to US Congress on the impact the recent ‘surge’ is having in Iraq, a new poll reveals that more than 1,000,000 Iraqi citizens have been murdered since the invasion took place in 2003.

Previous estimates, most noticeably the one published in the Lancet in October 2006, suggested almost half this number (654,965 deaths). These findings come from a poll released today by ORB, the British polling agency that has been tracking public opinion in Iraq since 2005.
