afghans I agree speically pashtuns , but rest of middle easterners are quite distinct
I have found Gulf Arabs, Iranians, Syrians, Lebanese, Jordanians, Palestinians, Iraqis, Egyptians, Afghans, North African Arabs, Berbers, Turks, Ozbeks, Kurds, Tajiks, and even some Sudanese who look quite similar to Pakistanis.
Throughout the Muslim world, there are definitely some common traits among us.
You cannot really generalize here. That is my main point.
Once you cross Pakistan-Indian natural border westward, we are all similar looking from my experience.
I actually don't consider Pakistan a South Asian country, but a Southwestern, Middle Eastern, and Southern-Central Asian country.
We have 220 million people who have come from all over the Muslim world, there is amazing diversity in our nation.
