Homefront takes place twenty years in the future, at a time when the crisis culminates in a war over energy and its supplies, whether oil or energy itself. The authors outline a fact that is approaching in the real world. Oil will not always be there and what will happen after that when there are no more deposits. THERE WILL BE WAR!! This is how the time in which Homefront takes place could be represented. The USA is an occupied country and the only hope here is you.
