The elite in Afghanistan have hated Pakistan before its birth. This hatred has not started after 1979. Most Afghans especially Pakhtuns do not accept NWFP or Balochistan as a part of Pakistan. The other ethnic groups of Afghanistan are less attached and less bothered about NWFP simply because they will lose their disproportionate influence over Afghanistan. They dont like Pakistan because they received very lttle support from them in the beginning.
I think the writer belongs to that very pro-India camp who love to glorify India and paint this very peaceful and development orientated image of it. He should be personally emailed (his email is on show for everyone) and reminded how India is not on friendly terms with any of it’s neighbours. At least Pakistan has China as a friend!
