have a nice day:
Rising threat of International War
There is a dualism in all things. Hegemony is no exception. It has both positive and negative aspects. Most people are familiar with the negative aspects, but don't perceive the positive aspects.
The greatest positive aspect of hegemony is the creation of a generalized peace in which the great powers do not war with each other. There are always localized wars, but not system wide wars. This was true for Pax Romana, Pax Mongolia, Pax Britannica Pax Americana.
When hegemony fades a geopolitical vacuum is created. Geopolitics abhors a vacuum. The great powers and incipient great powers rush in to fill the vacuum lest others succeed in doing so. As a result generalized war inevitably results. As American power fades the world is entering into an era in which generalized war again becomes possible.
So do you think after he's done, if he goes on the late night talk shows he'll admit there are aliens where Clinton said no?
