Have to confess mate, that we have SPOILED our neighbor with a VICTORIOUS 1971 campaign resulting in the changing of the Asian Map.
But than they don't understand that East Pakistan became Bangladesh not just b'coz of Indian help to the Mukti Bahini, but also b'coz of 13 days of effective campaign by the Indian Armed forces in the Eastern Sector. No way Pakistan is in that condition presently to fight such a war with India.
Also BD is NOT Kashmir or Vice-Versa. BD was separated by Pak through thousands of kms of Indian Territory, they weren't able to speak there own lang., even after being the more populous of the two WINGS, they were under represented in the national assembly, all the important developments & all the resources were utilized in the West while the EAST always found itself WANTING. I am not making an overstatement, but BDians were seriously thinking themselves as some sort of a COLONY of West. Add to this the fact that Mujib was not able to form the Govt. even after getting the majority & the resultant PA crackdown on normal BDian led to one of the Serious human rights crisis which resulted in not just lakhs but crores fleeing to India & finding Refuge here.
Again, none of the above conditions are effecting Kashmir.
We have given them enough autonomy with Article 370, they have enough representation in the LS, GOI gives enough funds to Kashmir for its development (infact more than what it adds to national GDP) & there is no separation b/w Rest of India & Kashmir.
+ Add another eg. to it, When USSR entered Afghanistan & effective campaign by mujaheddin with active support from Pak & US FORCED a SUPERPOWER like USSR to withdraw in 1989, Pakistan was sure that it can repeat the SUCCESS story in Kashmir (just see the dates which collides miraculously of Russian withdrawal & starting of Kashmiri insurgency).
But again, both are totally DIFFERENT cases:
1. Pak didn't find US support this time as in Afghanistan campaign.
2. Afghanistan was a completely different territory for the Leaders sitting in Moscow, but Kashmir is our very own territory since time immemorial.
3. USSR withdrew not just b'coz of Mujaheddin pressure but also the pressure on Economic & Political front it was facing back home which again is not the case with India.
So, even after 23 years, there is absolutely NO SUCCESS, in fact, the terrorist incidents are at it's lowest & Kashmir is at a relative PEACE & is Prospering well like the rest of India.
UN itself has now acknowledged that it's no longer an International Dispute but a Bilateral one, same is the case with the "Greater than Mt. Everest & Deeper than Marina Trench" Friend. US is now openly supporting India on this count.
I have no doubt that STATUS QUO of Kashmir will be maintained.
But, Even now if they want to give it a try, why not
