Found on Real Clear Politics website and cut from an article this passage, which is IMHO a good summary:

In the immediate aftermath of the assassination, the most pertinent commentary I read was by David Ignatius of The Washington Post, who had been a friend of Benazir's since they were together writing for the Harvard Crimson in the early 1970s:

"Bhutto's death is a brutal demonstration of the difficulty for outsiders in understanding -- let alone tinkering with -- a country such as Pakistan. The Bush administration attempted a bit of political engineering when it tried to broker an alliance between Musharraf and Bhutto and sought to position her as the country's next prime minister. Yesterday's events were a reminder that global politics is not Prospero's island, where we can conjure up the outcomes we want. In places such as Pakistan, where we can't be sure where events are heading, the wisest course for the United States is the cautious one of trying to identify and protect American interests. Pakistanis will decide how and when their country makes its accommodation with the modern world."
