My dear poster. Read some history please.
Prior to the September attack by India, Pakistan army did not cross "international border" from Punjab, or from Sindh.
Pakistan's only desire (and rather foolish one) was to gain in Kashmir the "disputed" territory. They wanted to continue low level insurgency going in Kashmir until the December at least, when many parts of Kashmir would be cut off from India due to heavy snow.
In all honesty, I blame Pakistani generals for ignoring international borders, and especially Lahore, thinking and perhaps assuming that Indians would not dare attack Pakistan's soft belly. This is even when Indians were openly threatening to expand the war beyond Kashmir.
To a neutral observer, Pak military's posture was clearly defensive (a weak defense dare I say) in Punjab, Sindh, and Bengal.
And Pakistan paid dearly for this bad planning. Lahore is practically at the border, and so many jawans and officers died defending and retaking the areas close to Lahore
Our saving grace was the collection of latest fighter bombers F-86, (and rumored spy planes) and superior training of pilots that stopped Indian army in its tracks.
So the bottom line:
Pakistanis never wanted to capture Indian areas across internationally recognized border. Read up a bit and you will find that there were no troop movements, no major deployments in Punjab, Sindh etc. beyond the basic and usual cantonments.
I urge both Paks and Indis to read a bit more on this. Mad jingoism won't help anyone.
