For more than one hundred years there were three recognized domains in military conflict: land, maritime and air. In the two last decades after significant debate, the cyber and space domains were officially defined by western allies. Rob Farley is in the studio with podcast editor Ron Granieri to explain why the United States and its allies need to consider adding the finance domain to the multi-domain discussion. Not to be confused with the economic lever of power in DIME, Rob makes the argument that the finance domain involves the technologies of finance and money that countries use to either maximize their own resource base or interfere in other states' abilities to maximize their resources. As with all discussions at the War College, he begins with Thucydides and moves forward in time examining the British pound, the U.S. dollar, the gold standard and looking forward at cryptocurrency and digital currency.
