Because they have nukes, nukes in the wrong hands= innocent people dead.Why do people care so much seriously, most of Africa has been worse than pakistan for years, parts of africa are controlled by rebels lets start worrying about that.
Pakistan is apparently a "leading ally with the US", i guess they need them cause of Afghanistan.
My solution:
Remove the tribal laws for a couple of years, and bring in the government laws let everything settle down then again let the tribal laws take shape.
So solution will never work, everyone know with half a brain it wont.
