The flow of blood may be ebbing, but the flood of money into the Iraq war is steadily rising, new analyses show. In 2008, its sixth year, the war will cost about $12 billion a month, triple the rate of its earliest years, Nobel Prize-winning economist Joseph E. Stiglitz and co-author Linda J. Bilmes report in a new book.
Beyond 2008, working with "best-case" and "realistic-moderate" scenarios, they project that the Iraq and Afghan wars, including long-term U.S. military occupations of those countries, will cost the U.S. budget between $1.7 trillion and $2.7 trillion -- or more -- by 2017. Interest owed to pay those costs could alone add $816 billion to that bottom line, they say.
The nonpartisan Congressional Budget Office (CBO) has done its own projections and comes in lower, forecasting a cumulative cost by 2017 of $1.2 trillion to $1.7 trillion for the two wars, with Iraq generally accounting for three-quarters of the costs.
Variations in such estimates stem from the sliding scales of assumptions, scenarios and budget items that are counted. But whatever the estimate, the cost will be huge, the auditors of the Government Accountability Office (GAO) say.
In a Jan. 30 report to Congress, the GAO observed that the United States will be committing "significant" future resources to the wars, "requiring decision makers to consider difficult trade-offs as the nation faces an increasing long-range fiscal challenge."
These numbers don't include the war's cost to the rest of the world. In Iraq itself, the 2003 U.S.-led invasion -- with its devastating air bombardments -- and the looting and arson that followed, severely damaged the country's infrastructure. Millions of Iraqis have been left without jobs, and hundreds of thousands of others have fled the country.
In their book, "The Three Trillion Dollar War," Stiglitz, of Columbia University, and Bilmes, of Harvard, report the two wars will have cost the U.S. budget $845 billion in 2007 dollars by next Sept. 30, the end of fiscal year 2008, assuming Congress fully funds Bush administration requests. That counts not just military operations, but embassy costs, reconstruction and other war-related expenses.
That total far surpasses the $670 billion in 2007 dollars the Congressional Research Service says was the U.S. price tag for the 12-year Vietnam War.
A fully funded 2008 war budget will be 155 percent higher than 2004's, the CBO reports.
Looking ahead, both the CBO and Stiglitz-Bilmes construct two scenarios, one in which U.S. troop levels in Iraq and Afghanistan drop sharply and early -- to 30,000 by late 2009 for the CBO, and to 55,000 by 2012 for Stiglitz-Bilmes -- and a second in which the drawdown is more gradual.
The two studies view different time frames, the CBO calculating possible costs met in the next 10 years, while Stiglitz and Bilmes also include costs incurred during that period but paid for later, such as equipment replaced in post-2017 budgets.
This factor figures most in the category of veterans' medical care and disability payments, where the CBO foresees $9 billion to $13 billion in costs by 2017. Stiglitz and Bilmes project $422 billion to $717 billion in costs over the lifetime of soldiers who by 2017 are wounded or otherwise mentally or physically disabled by the wars.
"The CBO is only looking 10 years out on everything," Bilmes noted in an interview.
For its part, a CBO critique suggested that Bilmes and Stiglitz might be overstating the expense of treating veterans' brain injuries, a costly category.
They say their calculations are conservative.
Estimating all economic and social costs might push the U.S. war bill up toward $5 trillion by 2017, they say.
