If the governments of world were somehow suddenly banned from borrowing money from the international bankers to fund wars, the world would be at peace. As long as the bankers are able to loan money to the nations of the world, we will experience perpetual wars.
Wars enable the bankers to redistribute the wealth of nations to the bank vaults of the financial elite. In order for the nations to repay their war debt, the people pay the price with increased taxes. Wars are often instigated by the bankers in order to increase their profits and to enslave the people with mountains of debt.
When a nation has a debt based currency, taxes are needed to pay the interest on the money borrowed. If a nation refused to borrow money they would have not need to tax the people in order to pay the interest required by the bankers.
