. Afghans will continue to enter Pakistan, not because they have an agenda or because they are paid by India, but simply because they are desperate and poor. Blame yourself for landing them in that situation by supporting insurgencies there for the past 30 years. Now with the Taliban takeover, it will get worse. Western Aid is going to dry up and Talibs obviously don't know how to run a country so any economy there will be obliterated, except poppy trade of course. A Millions more will flood in, nothing you can do to stop it.
