Whether Imran khan pulls down the PM or not thats secondary..He has established himself as a very lethal pressure group who can at will sabotage any city ,Town and pressurize any issue into hapening or not hapening which is initself a power.What is prime-ministership? it is an executive ability to make people obey.By that definition he is already a primeminister.He can pull crowds where and at will.People more than obey him rather they spend money to elevate his causes.Thats an awesome power.Pulling down Nawaz sharif is secondary.Even Imran khan knows that himself he is only trying to establishing himself as a worthy stakeholder.Thats good for us all..
