Your army is being sensible and trying to freeze / secure what it has. While people in this forum have a weird sense of capabilities of your nation, fact is, Like China has claim on Taiwan and South China Sea, India has claim on J&K , including Gilgit Baltistan. Like China, India is working to make it stronger and capable and waiting for right time.
Your Constitution does not recognize J&K as your territory...till date. You want the voting to happen. If India annex the area currently occupied by Pakistan, it will Constitutionally and legally speaking, will move to areas which is recognized by Indian's Constitution and Treaty of Accession. One more think, India will claim it on behalf of Indian Muslims, who are equal citizens of India and more in numbers ( post east pakistan) and despite all the propoganda, you will see a Muslim PM of India who will take it back and Muslims of India will fight to take it back. You will find India leading OIC in future too.
Time changes.
