In this particular case, I dont see how it is applicable to either India or Pakistan. Both the countries are making a wise decision which benefits them both.
India has surplus electricity in almost all the States that border Pakistan. This power cannot be wheeled across to the power deficit States which are either in Eastern or Southern India unless at huge cost.
On the other hand, Pakistan is power deficit.
In both the cases, its the people who will benefit. Pakistani's will get electricity(directly) and Indian taxpayers will get some relief(indirectly).
The real fun will be when we export Petrol, Diesel and Gas to Pakistan.
Give it a couple of years...you are going to see it happen
