India wasn't fighting the Bangladeshis either - they were fighting the West Pakistan army. Argentina's aircraft carrier spent most of its time in the docks.  Also, some of the toughest fighting was done by the Gurkhas. 

India had an aircraft carrier too, which took active part in the war. Google and find its name.. 

As for Korean War era weapons, the Mig 21 was not around there. Neither was the F-104. The T-55 tank was not around either. Neither was the PT-76.  But it was around in the 1971 war.  Unless your Korean War took place in 1971.

If large military casualties symbolize ineptitude, the US, Brits,Russians, Germans, etc lost in the hundreds of thousands to millions during WW2. That must make them 1,000 to 10,000 times more incompetent than the Indians and Pakistanis!
