The problem with many educated Indians is that they become illogical when it comes to Pakistan.
If you didn't have a "extreme" bias against Pakistan and Pakistani army, you would have come up with a plausible answer yourself.
You probably know that Afghanistan's lifeline is dependent on Pakistan in every which way, militarily, economically, industrially, and agriculturally.
We never asked the world to help us with economic, industrial, and agricultural support of Afghanistan.
The only exception is military.
If Indian planners were not "extremely biased" against Pakistan, they would have established a joint military plan with Pakistan.
Sadly though, many Indian posters on this forum (including yourself) and majority Indian intellectuals in Dilli have said by to logic on this issue.
and hence your question.
Hope you don't mind me being to straightforward on this.
thank you for being a good listener.
