^ Look, India cares about Afghanistan because it wants to keep Pakistan at bay. There is no denial in India or elsewhere. But to say that India is supporting people attacking Pakistan is ridiculous.
India has its vested interest in not having Pakistan spreading its influence there. Remember Taliban, hijacking, safe haven. India does not want a repeat of taliban and people sympathetic to it in Afghanistan and act as a magnet for attracting people opposed to India.
If Pakistan is feeling threatened then they should increase their humanitarian aid to Afghanistan and work with Afghan govt. This way India will not have any premise to be in Afghanistan at all.
