A quote attributed to U.S. Gen. George S. Patton, that "all glory is fleeting" presents a lesson on humility and the impermanence of power that is not always grasped by some of today's world leaders. The hubris of aging or ill despots who cling to power, reinforced by sycophantic aides and fawning followers, can lead to instability for their countries should they succumb to death. It is an issue that stretches back to antiquity. Alexander the Great's sudden death after an acute illness at the age of 32 led to the division of his vast empire. Had the great conqueror had access to the benefits of modern medicine, his reign might have been long extended. That is the case in many countries today, as heads of state cling ever longer onto power thanks to medical advancements and the political environments in which they operate.
