Manana Dr Swati and welcome back!
I would say that prior to 2007 Pakistan was stable albeit with an insurgency confined to the north-west, just as Turkey is seen as stable but with a Kurdish insurgency in the south-west.
Then in 2007 two things happened.
1: The whole chief justice saga.
2: A huge explosion of "suicide bombings"
So for the past 5 and a half years, Pakistan has become a nightmare.
We will have to see what happens, however Gilani was I think Pakistan's longest serving prime minister (?) and this PPP administration may miraculously serve its full term in office!
