If everything that you mentioned as list happens (army kicks out both AZ and new elections are held 6months later) how would that guarantee new people with fresh ideas? As any election from current lot will make one or the other crook as PM and President.
ehtasab bhaijan. Don't give up hope so quickly. If the unthinkable happens, then remember, Qazi Hussain and Imran Khan did not take part in the last elections. They could be the new faces (President and PM) of Pakistan. :)
