Actually, Indian forces were helped by the fact that..
East Pakistan was thousands of miles from west Pak, with nothing but enemy territory in between, hence cut off.
India surrounded East Pak on three sides.
And Pak was also to deal with an internal guerilla movement that was aided by India.
So under those circumstances, very difficult to fight any war.
So continue to delude yourself, but East Pakistan was hardly a victory of superior arms, but a victory of circumstance.
We all know how capable your army is in fighting an actual fight.
The Chinese proved it effectively. And Pakistan, being 1/10 the size, was still able to fight you to a standstill 
So the all the mighty brown midgets of the east have to soothe their bruised ego is East Pakistan, which wasnt even their victory:hehe:
And ask Kashmiris how peace loving you are…
