Sooba Sarhad was part of Sooba Punjab until 1902 - A bit of history

Marwati, with due respect, you have not read the history of British-India.

Just a hint.

During 1946 (the most recent role of Badshah Khan), he was part of the Indian Congress team negotiating with Jinnah.

What was Indian congress's political stance in 1946?

From Khyber to Calcutta there is one country and that's all.

Indian Congress allowing Frontier to joining Afghanistan? simply haha- and then hahaha,

Your ill-thought statement would have brought a lot of rebuke by anyone with a single iota of knowledge. But one has to digress.
