The assassination of Benazir Bhutto surprised me, although I can't think why that would be the case. The terrorists dominating the Northwest Province in Pakistan have been promising to kill her for a long time.
What al Qaida may have done, instead of eliminating a political enemy, is to create an invincible foe. A dead person can't say something stupid. A dead person can't make political miscalculations. A dead person can't get caught stealing or cheating. Benazir Bhutto has become a flawless symbol of the desire for democracy.
What Pakistan is looking at now is the unifying effect of Bhutto's assassination on the entire country. Knowing this, the purpose of postponing elections would be the hope that time would erode some of this effect. Let's hope they don't. It would be better to forge a new government when some unity can be fashioned out of this terrible event.
