Agnostic to answer your question, its a fallacy when people say that to get Azad Kashmir, war is the only option. Yes it is one of the options, and a very bad one at that, but there are other ways to do it. If people do not start hating me, i will try and give a fictional case. It obviously depends on a series of evens coming true before that. First is happenings in Pakistan, events in India, and global events.
If the current instability in Pakistan increases, the religious and ethnic fault lines will be exposed. Right now the major fault line within Pakistani society is religious i.e. extremist v army v liberals. But Even our Pakistani members cannot deny that under the surface there exist ethnic divisions between Baloch and Punjabi, Pashtun and Punjabi, Tajiks, Uzbeks, and Sindhis. If the writ of the government keeps receding from the hinterlands like right now, these separatist movements will gain momentum, and after a critical mass is achieved by either of them, it will lay the foundations of Pakistan exposed. Now on their own these movements are bound to fail, but if a foreign power, like the US starts exploiting these fault lines for its own benefit, it would give these movements recognition. The most important help that these movements need is diplomatic recognition and world support. This the US and India can do easily. Afghanistan's refusal to recognize the border has created the basis for NWFP's secession. Baluchistan freedom movement, if supported by Iran, US and India will provide the basis for secession of Baluchistan. And so on so forth.
Now what India needs to do is strengthen its ties with Afghanistan, US, Iran and keep its claim of Azad Kashmir open. It also needs to question the stability of Pakistan in world forums and media, in order to sow the seeds of doubt in the mind of foreigners and Pakistanis alike about the viability of their state, and tsk tsk, thats exactly what India is doing. The aim would be to dis integrate Pakistan from within without resorting to war, by exploiting the ethnic fault lines in the society and a creating doubt about the viability of Pakistan as a nation in the world view. The raw materials all exist, only a good cook is needed. If and when this implosion happens, India should be at peace within its borders, and economically sound. In that scenario India can offer a chaotic Azad Kashmir the choice of ascession into the union with the promise of stability and prosperity, or India could just move in and occupy Azad Kashmir while Pakistan is being created all over again. The ideal solution would be an independent Balochistan, NWFP absorbed in Afghanistan, and a truncated Pakistan comprising Punjab and Sindh only.
Yes this is a far fetched scenario, but like i said, the raw materials for this recipe all exist even now. It might take decades or even centuries, but India can wait.
ahhh don't hate me now !! Just wet dreams of Brahmin hindus. Im not even a brahmin though
