Pakistan is already a failed state and a nuclear one at that.
Pakistan is financially bankrupt, and has ceeded control of the North-West Frontier Province (NWFP), the Federally Administered Tribal Areas (FATA), and Balochistan Province to extremist forces. For all practical purposes, Pakistan is now a bifurcated nation split almost exactly in half. Islamabad is being encircled in a pincer movement from the west and north.
Since the government refuses to pull any military forces away from the border with India, the internal situation will certainly get worse in the coming months. The civilian government in Islamabad is only a few suicide-bombings away from falling.
No one has a clue how to save Pakistan from itself.
