Dude,
British, Soviets and Americans - each had numerous allies on the ground in Afghanistan, and still failed. They tried everything you can think of. They were just as confident as you are right now, at the start. Slowly but surely, it dawned on them that even hybrid tactics are not working.
The so-called Mujahideen who confronted USSR were not just Afghans; many of them were foreigners. They learned how to communicate with locals (Afghanistan and Pakistan), studied the landscape and drew battlefield plans accordingly. And Pakistan extended its help in whatever ways it could. Idea is to weaken and exhaust a conventional force in a protracted confrontation, until the opponent caves in.
In no way or form I am underestimating Indian conventional strength but it simply doesn't work against the kind of forces I am alluding to.
You should study Soviet - Afghan war in detail. You will see my point.
I have seen US - Afghan war up close, and what I see today is frustration. Even myself (as a neutral observer) - am frustrated. I do not want Afghan Taliban to win, but it is happening.
