Violent death is horrifying. This may be a time to assess the import of having the same surnames over and over again in the top leadership of many countries - India, United States, Argentina, Singapore and Pakistan come to mind. In 2000 Andrew Sullivan decried the importance of branded names in American politics- where access to money and name recognition trump experience, potential and talent (and here in Illinois we have this problem at all levels of government).
The problem with dynasties is that they crowd out better talent and they degrade political discourse. Sure Benazir had the best of western education and presumably learned much at the knees of her father, but for what effect? What happened during her tenure in office? Is it just the impossible situation in Pakistan, a country born on false promises teetering between militarism and religious extremism? Or is it partly because political cultures that defer to pedigree are bound to fail more often than not? For example, has India prospered and become more dynamic inspite of the Gandhis?
