Koi nahi phassa. Merai zehan main 1 doosra jo aam taur par bharation kai zehan main hota hai.
As for Baluchistan. Let me teach you about it. It consisted of two regions. One was British Baluchistan which consisted of Quetta and Northern Baluchistan. This british Baluchistan was bound to join Pakistan since it was Muslim majority and wasn't ruled by any Raja or King. The rest of the part was called Kalat state.
This kalat state joined Pakistan later peacefully as ist ruler also signed the papers later.
The case of Baluchistan was different from Sindh since there was no assembly and present day Baluchistan province was divided into two regions unlike Sindh.
