You need to understand Pak cant blackmail a country in the name of nuisance. India wants to be global power in future in yhe line of USA, Russia and China, and Afghanistan may prove a first small step towards it, it has nothing to do with Pak as Pakistan is being taken care of on its western borders but it may prove a hidden card opening a second front against Pak in war but its definitely secondary.what makes you think Pakistan is looking for the welfare of Afghanistan, neither is India...both are looking for their own interest. India's interest is to create problems for Pakistan and Pakistan's interest is to kick India out of there. As far as India's business lobby is concerned any business lobby will come to Afghanistan once their is peace and that peace can only be achieved by keeping good with Pakistan not India and that my friend is in the interest of Afghanistan.
