It should be who will save you again from TTP, after US is gone Afghanistan will be at civil war, doesn't matter what the agreement is. Northern alliance, Taliban, local warlords and all, in your backyard.And who will save India from talibans+pak+china? Do you have any plans xd
How hard do you think is to get few warlords for India? Specially when what is good for Islamic Afghanistan can be good for Islamic Pakistan? Isn't why TTP is treated brotherly by Taliban?
I won't say much but American withdrawal will be your nightmare for Pakistan. First Pakistan won't have anything left on diplomatic front, second the breach of agreement under your guarantee will make the situation even worst and third no US to save your *censored*.
Make a list of worst Pakistani enemies and see how many of your 'brave' army killed. Billions after billions were spent on one operation after other, with significant population displaced and yet not a single enemy leader was killed by Pakistani Army.
Who do you think will kill them for you after US is gone? Taliban? Really? Have they ever? Listen to most radical of your analysts, who served time with Taliban and ask them if Taliban will even give you whereabouts of any TTP leader, infact that shield them otherwise they will look hypocrites and unlike Pakistanis others have some reputation to protect.
You can quote me later after few years, if America withdrews it will be a nightmare for you. And if you think you can train terrorists in Afghanistan and then send them to Kashmir you are already doing it. Doing it from your own land and what does it achieve?
In 90's it was successful because we didn't have border protection mechanism so anyone can infiltrate and attack, now it is so strong that your TV channels cry for your pigeons being caught. Except this there is no other advantage for you in Afghanistan and I have listed what awaits you based on reality not assumptions and delusions.
