"The World Without US" debates the implications and consequences of US military involvement in the world today. From an isolationist nation at the end of World War One, the US today has bases in over ninety countries. No other nation has been able to project military power as the US does today. But is such an involvement sustainable? Despite its might, the US is shrinking in terms of population and economic power in relation to the rest of the world. So, what would happen should the United States leave the international scene, and become again a "normal nation", a republic, and not an empire?"
