Where are their homes?,where are their properties?. Are these occupied by other peoples and why?
Afghan govt is responsible of this or northern people. It is the easy method of occupation of the properties of others to migrate them and occupy their properties.
The stability of Afghanistan is not the responsibility of Pakistan, Afghan taliban does not like the presence of India in Afghanistan, because it (India) provide weapons to Afghan govt against Afghan taliban.
