Is Pakistan disintegrating & collapsing.. question when did you visit Pak last time? Is their any trouble in any part of Pakistan except NWFP? The people who know can understand this easy-thing why their is trouble in NWFP areas only. Don't worry, the state of Pakistan knows what they are doing, even we are small country on the world map, but indeed we also have to make sure that USA/Europe won't stay forever in Afghanistan or next to our borders :)
But the Taliban are slowly advancing. They took SWAT. Just last year you would have said that no way the Taliban would take over SWAT.
Here goes your US forces attack & take the nuclear devices theory goes into dust, look at your own response, their so-called contingency plan's won't work at all. Even Pakistan dis-integrate even Sindh, Balouchistan & NWFP gone .. even.. Punjab fell into civil war, let me assure you Nuclear devices will not be harmed at all. How i know all this? Lets say i have little knowledge of how the protection system work.
I think you forgot to read my last sentence. the Danger of fissile material to make a dirty bomb is still real.
