Feudal society? I think at that point you won't be looking at something that resembles fiefdoms so much as global hegemonies.... I am not sure it will get that far though. More likely it will expand until the economic stress from an oversized national security budget and rising energy prices will force it to collapse with global consequences. For the record, no, I do not think those consequences will be pleasant for anyone :-P
