One thing is for sure and that is: Musharraf or even Zia never had so much control over government as much as Nawaz would have if PML(N) comes to power or Zardari would have if PPP would come to power.
At least people in government could have showed descent to Zia or even Musharraf (as both Mush and Zia allowed that) but if Nawaz would tell his party so-called leaders/followers (slaves) to eat cow dung than they would do that declaring that cow dung is Sohan Halwa and if Zardari would tell his party so-called leaders/followers (slaves) to drink cow urine than they would do that declaring that cow urine is Aab-e-Hiyat.
To have power, both Zia and Musharraf had to force constitutional amendments but these thugs do not need that, as their party members are their slaves. If Zia was virtual dictator and Musharraf was dictator by name, these two are dictator to the core.
Problem is that, until Pakistanis come out of their slavery, their dictatorial rule would stay over Pakistan for many generations, as both intend to pass Pakistani slaves to their kids ... and so on.
My dear friend...Pakistan is the quom of Danda...Period!
