When you have Afghan refugees in Pakistan, and they being Pashtuns like we have, how can you judge whether they are Pakistani or Afghani ? If you are aware of politics in Pakistan, the government decided not to keep Afghanis who were living here for more than 30 years. It is evident at this point that they are going back. Its a stupid thread that does not have any evidence to make it's claim. Prove otherwise for Punjabis and Sindhis....
After Carribean and Africa massive migration from India, such likewise incident still continues today. When India is a country of 1.2 billion people and is so called 'economically rising' you would no need to even go to small islands like UAE, Bahrain, Qatar and make most of the ethnics there still....LOL.
