I think Pakistanis have been kept in a bubble for too long, protected by constructed and alternative histories. The propaganda fed is so dense - there probably was no chance to examine the faults or mistakes committed in history, because they were told they have always been right and righteous and the only reason for their fate is some evil conspiracy. Whenever they are faced with facts contradicting their fed history, they simply refuse to believe them. They would rather call the facts as a conspiracy. May be it became a habit now. No one is ready to accept that he/she or his people did something bad like a suicide bombing.
