Hmmm...not too long ago, Pakistani forces captured a 15-year-old aspiring terrorist who was allegedly part of the ring to assassinate former PM Benazir Bhutto, and said teenager confessed to his involvement.
Now, according to Bhutto’s own words, excerpted from her posthumous autobiography, another 15-year-old was involved in her assassination as well...Osama bin Laden’s son. And she knew why she was going to be murdered:

First, the extremists aim to reconstitute the concept of the caliphate, a political state encompassing the great Ummah (Muslim community) populations of the world, uniting the Middle East, the Persian Gulf states, south Asia, central Asia, east Asia, and parts of Africa. Second, they aim to provoke a clash of civilisations between the West and an interpretation of Islam that rejects pluralism and modernity. The goal, the great hope of the militants, is a collision, an explosion between the values of the West and what the extremists claim to be the values of Islam.

Simply put, Bhutto knew the score, and therefore targeted by the Islamofascists.
