" The great danger to an empire is permanent war. Given global interests, something is always on fire. If the primary response is war, the empire will always be at war. And if it is always at war somewhere, it will always be vulnerable to someone taking advantage of the empire’s preoccupation. Even more important, if the empire doesn’t benefit its citizens, but instead exhausts them and disrupts their lives by war, the political support for the empire will quickly evaporate. Both Rome and Britain survived by using minimal direct force, in favor of other means of managing their empires. "
