I don't understand where the questions and discussions centering around occupation come from. We broke Pakistan into two, yet let the liberated keep their newly renamed country. When in HISTORY have Indian armed forces ever coveted foreign lands (and here I refer to our 5000 year history - during which the farthest we went was the SE Asian island colonies of the Cholas I think)?
Granted that what is Pakistan today does not exactly fit into the definition of a foreign land, but their people sure do. Even if we want our land back, what are we going to do with the millions of them that are still remaining after we finish with them? Occupation is not going to happen. We will retake what we believe is ours. Even if it means taking some of theirs as bargaining chips. But we do not want them back into our fold. We would be mad to even contemplate something to that effect.
De-fanging them for posterity serves us just fine. Letting nature then take its course on what was a flawed concept from its very inception.
