Nothing to do with it! Well very little. Wars makes America lose money and go bankrupt. Where do we get money from if we have none, well we borrow it at interest. Who do we borrow it from? English banks which lend money to a company called United States at INTEREST.
Again look at who has the most to gain when a country needs to borrow money to fund wars!
