The world is a whole new place. After World War II, we just couldn't adjust. People clamored for protection and economic prosperity. People took a couple years to sort everything out before going on a territorial rampage. With new technology, wars now take days to complete, rather than the months or years originally projected since WWII.
People like Mr. Hull and Alexander now struggle to keep the peace; and they're failing. With rapidly expanding militaries, a peacekeeper evaluating his stance in life, and an evil plan afoot, it seems that it will be only a matter of time before the previously unthinkable happens. World War III.
