" ... THE UNITED States currently confronts foreign policy challenges  involving such highly disparate foes, friends and in-betweens as North Korea,  Syria, Saudi Arabia, Indonesia, Azerbaijan, Jordan, Morocco, the Congo and the  Philippines. All these countries, however, possess one striking common  denominator. Although dynasticism is supposed to have died and been buried by  meritocracy, these countries are all led by the children of former heads of  state.
 The same is true of America, whose president is not just the son of a  president, but also the grandson of a senator and brother of a governor.  Americans tend to be willfully blind to the crucial subject of nepotism. We  disapprove of it, so we feel we ought not to think about it--a dangerous  illusion as we pursue a more activist foreign policy that brings us in touch  with cultures that approach the topic quite differently.
 The return of family rule should not surprise us. Nepotism and its more  formal offspring dynasticism have provided the basic organizing principles of  politics for much of human history. For example, in the early 20th century, the  ruling aristocracy of Mongolia, which comprised 6 percent of the population,  still consisted of the descendants in the direct male line of Genghis Khan, even  though he had been dead for almost 700 years.
 Indeed, Genghis Khan, who was known as The Master of Thrones and Crowns, was  so successful at propagating his lineage, both by fathering countless children  and granting some of his heirs enormous and enduring political privileges, that  his genetic footprint on a vast swath of Asia from the Pacific to Afghanistan  leaps out at population geneticists today. A 2003 study of male Y-chromosomes  discovered that about 16 million living men are his direct patrilineal  descendants. That's a level of dynastic success, in the Darwinian sense of the  term, approaching one million times greater than that of the typical man who was  alive back then.
 As ferociously exemplified by The Mighty Manslayer, this urge to help copies  of one's genes survive and spread is the basis of nepotism, which biologists  define as altruism toward kin. It encourages human beings to help their  offspring and relatives achieve power and prosperity.
 The recent book In Praise of Nepotism by Adam Bellow (son of Nobel Laureate  Saul Bellow) documents how the great English biologist William D. Hamilton's  1964 elucidation of the genetic reasons behind altruism toward kin formed the  plinth upon which the field of sociobiology was built. Hamilton's paradigm  became more widely known from Richard Dawkins' 1976 bestseller, The Selfish  Gene. A more accurate, if still anthropomorphic name, would have been The  Dynastic Gene, since genes thrive by promoting copies of themselves in  others.
 Of course, biology can explain only the rudiments of the manifestations of  family feeling in the political world. Further, scientists have barely begun to  consider the flip side of the desire to establish a dynasty--the widespread  desire to he ruled by one. Evidence for the resurgent importance of dynasticism  and nepotism is everywhere. In a broad swath of southern Asia, running from  Pakistan, through India, Sri Lanka, Bangladesh, Indonesia and on to the  Philippines, the dynastic urge has often worked in conjunction with the  democratic impulse. In each, voters have chosen widows or daughters to carry on  from their late men-folk the family business of running the country.
 Some of these women entered politics to avenge the killing or overthrow of  their husbands or fathers. For example, Corazon Aquino was elected president of  the Philippines following her husband's assassination by dictator Ferdinand  Marcos' goon squad. Benazir Bhutto ruled Pakistan after the downfall of General  Mohammad Zia Ul-Haq, who had overthrown and hanged her father. Indonesian  president Megawati Sukarnoputri is the daughter of the former leftist ruler  Sukarno. Sheik Hasina, prime minister of Bangladesh from 1996-2001, is the  daughter of the founder of independent Bangladesh, Sheikh Mujibur Rahman, who  died in a military coup in 1975.
 In India, the Congress Party chose as their leader in the 1999 election Sonia  Gandhi, widow, daughter-in-law and grand-daughter-in-law of prime ministers. She  lost party control, though, after leading Congress to merely a second-place  finish. Runner-up is considered a disgraceful performance for anyone bearing the  magic name of "Gandhi." The high hopes invested in Sonia were testimony to the  glamour of the dynasty. Without the Gandhi name, Sonia--a Roman Catholic Italian  who doesn't speak a single Indian language terribly well--would have been just  about the least likely person to become head of a major Indian party. ...
