The supremacy of American economy completely lies on the high value of dollar. Again the high value of dollar is due the petrodollar concept where every OPEC countries need to sell oil in dollar only. Libya, Iraq, Syria and all other such countries that have made serious resistance against such superiority of dollar were instantly demolished by the American military force. America can’t afford any resistance against the rule of dollar. Now there is China who is creating severe steps to prevent the reign of dollar with the help of few other allies. Thus currency warfare is the complete reality between China and America and it may easily lead to a real war which will going to be more severe than any of the wars the world has ever observed.
