The day is not far when Islamabad will be in the hands of the mujahideen

[zombie]

Well many circumstances can be created to overvcome Islamabad like

A host of Suicide Bombings followed by a flurry of militant activities.

A Lal Masjid like take and hold with larger numbers.

Or using a destroyer XXXXXXXI from space and zapping the city with alien killing beams.

Out of the three I think the third is more likely for the take over of Islamabad.

Thanks for confirming how impossible it is for Taliban to take over Islamabad any other way.
