Pak is not a failed state .
However none of the points listed in post #1 could prevent a nation from becoming one.
Personally I am against the term "Failed state". Still if some unit of measure has to be applied, it should be more to do with governance, national institutions, rule of law etc.
P.S. Add economy and the ability of a nation to pay its debts.
India has the same amount of chance of being a failed state as Pakistan. In fact, even countries like the US has an equally likely chance of being one. Pakistan has well functioning institutions, growing economy, reasonable infrastructure, various sources of 'income' (exports), a huge consumer market, natural resources. I think Pakistan has same chances of failing as India or any other country does.
