In all this planning did Pakistan think that India with its superior conventional military power would allow Islamabad to hold on to the advantage. Here comes Pakistan's first misjudgment. It would have been impossible for India to let captured areas remain under Pakistan. It would have made a concerted effort to send out the Pakistanis this year. If not, then next summer.
Pakistani strategists misread Indian military capability.
It is no military wisdom to think that it would get all the advantage and the opponent would be left high and dry - an opponent like India which has defeated it in the past. Another miscalculation was that India would not use its air power. In the first few days it tried to beat back India's air power by shooting down three of our aircraft. When the Indian helicopter was also downed, Pakistan perhaps realised that India would not let go, whatever the losses. That is why Pakistan did not try to trifle any further with our aircraft.
