Add in all the wars since WWII — the US has been living with a negative ROI the whole time, & has somehow managed to this point to kick the can down the road on paying it off. Had the foreign adventurism of McKinley and Roosevelt, as well as Wilson's crazed forcing the US into WWI not gotten into the nation's blood, imagine how well-off its people could be.
