What country spent the most money during World War 2?

The war costs to the US was $288,000,000,000 and the costs to Germany slightly less at about $212,336,000,000, according to the D-Day museum as reported by the National D-Day Museum. (Someone once said that even the little things cost a whole lot if you buy enough of them.) Figures lie and liars figure, or so the story goes, and after all, who cares, its only money.
