Balochistan had legally & willingly joined Pakistan, although this is offtopic but let me clear your mind, Balochistan was not in this form as it is today but there were different states namely Las-Bela, Kalat, Kharan, Makran, Gawadar & Pushtun Areas...Las-Bela, Kharan, Makran & Pashtun Areas joined Pakistan riteaway the State of Kalat took the decision to their parliament, most members opposed to join but the Khan of Kalat who was the ruler decided to join Pakistan(if you want video proof of Grandson of Khan of Kalat i can post it too), not to mention that Kalat state was in the middle of all other states & Sindh on other side. Gawadar was later purchased by Govt of Oman...so don't talk what your media/army propaganda machines tells you...the world & the UN accept Balochistan as legal territory of Pakistan without any doubt...Balochistan is as Pakistan as Maharatra is india.
Kashmir case is totally different from this & is considered as disputed by whole world & UN.
Yes we can't give freedom to everyone thats why we backed off from Hyderabad Deccan, UP, Bihar & most times Junagadh/Manvadar. If Pakistan can back off from soo many territories for Peace why can't india.
Go tell the oxford dictionary that the meaning of the word "whole world" has been changed to Pakistan. No one outside Pakistan and India cares about the Kashmir Issue ,and even if some random arab country cares , they know they can do nothing about it. If anyone actually cared about Kashmir issue , they would have done something about it. Kashmir issue has been in the UN ever since 1947. It's like a past time for world delegates. They just attend conferences on Kashmir for entertainment , fully aware that they are not going to do anything about it.
As for the crap you wrote about Junagarh , Hyderabad etc etc , they were never yours in the first place. You did no favor by not claiming them. Even if you had been claiming them , it would make no difference, just like the case in Kashmir.
