Earlier quoted context omitted.
>We invaded and occupied Iraq and didn't even get any oil, just a trillion or so in national debt. At least in the time of Rome citizen soldiers were titled large swaths of land in the conquered territories. The trillions in national debt benefits somebody. Somebody somewhere gets those interest payments and they wouldn't have if the U.S had not borrowed from them.
...and the point wasn't to "get the oil" necessarily, but to take control of it so Hussein wouldn't flood the market and make the price go down .
Truth is the story's likely complicated.
