BOSTON (Reuters) - The cost of the Iraq war could top $2 trillion, far above the White House's pre-war projections, when long-term costs such as lifetime health care for thousands of wounded U.S. soldiers are included, a study said on Monday.

Columbia University economist Joseph E. Stiglitz and Harvard lecturer Linda Bilmes included in their study disability payments for the 16,000 wounded U.S. soldiers, about 20 percent of whom suffer serious brain or spinal injuries.

They said U.S. taxpayers will be burdened with costs that linger long after U.S. troops withdraw.
