The former prime minister was assassinated Dec 27, 2007, after a Pakistan Peoples Party rally in Rawalpindi, just two weeks before the scheduled parliamentary elections of 2008.
An editorial in the News International Tuesday said: "Her (Benazir's) death changed our history; it may have changed our destiny and is perhaps one reason at least for the pitfalls we have stumbled into. Perhaps Benazir could have prevented some of this."
"But speculation about what could have been serves very little purpose and does not help us today."
It said that the country has to live with the facts - and "some of these are extremely disturbing".
"For one, it is a true irony that even with Bhutto's own PPP in government, even with her husband ( Asif Ali Zardari) occupying the presidency and her son (Bilawal) heading the party his grandfather founded, we are no closer than before to solving the riddle of Benazir's murder," the editorial said.
"Indeed we seem further away and need to question why this is the case."
The editorial went on to say that a commission the government set up to look into the murder has submitted a report which the PPP top brass has decided to keep a secret.
"Essentially we stand rooted at the same spot where we were in 2007. Fingers point in many directions; there is no real evidence to suggest which version is the most accurate.
"As is also true of so much else in our history, we may never learn the truth."
Describing it as a "disturbing thought", the editorial said it raises all kinds of doubts in our minds, and "perhaps the most striking among these is why our current set of rulers, given their affinity to Benazir, should be quite so reluctant to uncover the truth and place it before the people."
"The uncertainty that persists is unsettling. A woman of as much sagacity and courage as Benazir deserved better."
