Define proof. Confessions from top Taleban commanders, isn't that proof? American politician(s) openly requesting India to reduce its influence and continued activities in Afghanistan, isn't that proof? Or do you really believe that the Indian government has spent 1.2 Billion dollars in Afghanistan (some would say paid-off the illegal Afghan government) because they're great humanitarians? I hope you're not that naive. Even the most hardcore Indian must smell something funny here, it's only natural.
Come on. We could go back and forth all day, but you've already made up your mind, so there's no point arguing. If I had a nickel for every Indian who would mindlessly deny any Indian involvement in Pakistan, without any proof, I'd be a millionaire. Anything they say will be based purely on nationalism and not contain an ounce of rational thought, which is why the smart Indians on this forum stay away from such debates. It's best to get off this subject, and stick to the topic.
