"The extra spending in Iraq is adding to a U.S. budget deficit that the president has vowed to cut by half in the next four years.

"By pushing war spending beyond $300 billion, the latest proposal would approach nearly half the $613 billion the United States spent for World War I or the $623 billion it expended for the Vietnam War, when the costs of those conflicts are translated into 2005 dollars." - Assciated Press
