Actually before starting the war, the idea was to occupy half of east pak and trade this with the half of kashmir left out in paks hand, after indian army reached the middle of dhaka, Niazi got scared and bluntly surrendered, instead he could have put a good fight with 93000 soldiers and declare ceasfire ( which india expected),but hte whole scene changed, even afetr the surrender , indira gandhi could have negotiated the kashmir deal, but she wanted to get the name \\\\\\\\\\\\\\\" creator of bangladesh,which actually goes to indian army\\\\\\\\\\\\\\\'s credit, at the cost of indias future. Had the deal been negotiated then, there would not have been any kargil, we could have paid them back in the same coin for terrorism they are sponsring with the help of mukthi bahini. But as is the case with india all the time, personal inetrest dominated the national interest.
