In 1971, India was a financially bankrupt country, while Pakistan had one of the fastest-growing and strongest economies in Asia. Despite this, it took India only 12 days to invade East Pakistan, force Pakistan to sign surrender documents, and declare East Pakistan an independent country
Is such amusing revisionism prevalent among all Indian educational institutions?
You forgot to mention that for 9 months prior Bengali locals had already captured most of the country for you, and that India had a 50:1 numerical advantage and total logistical and air supremacy against East Pakistan. IAF had 160+ jets, PAF had barely 16.
Still, India managed to lose some battles like at Kamalpur, where a brigade (2,000-4,000 soldiers) of Indian Army could not dislodge 40 Pakistani soldiers. By the end of the war Pakistan still controlled much of the cities it started with.
In 1947, Pakistan was
actually bankrupt to the point it could not afford chairs and desks in govt offices.
Still, Pakistan swiftly invaded Kashmir with pathans and gilgitis wearing chappals, and forced India to surrender an area the size of Austria to Pakistan. This was despite India having an air force, armour, and outnumbering Pakistan.
Every war has ended with India permanently giving up territory to Pakistan:
1947: 86,000sq km of Kashmir (India surrendered whole Gilgit-Baltistan)
1965: 900 sq miles of Gujarat (Indian invasions of Pakistan failed)
1971: 120sq km of Kashmir (despite so called decisive Indian victory)
1999: Multiple peaks in Kargil (India begged the US to pressure Musharraf to withdraw)
I don't know where Indians get their undue overconfidence from - but I'm happy to get a good laugh out of it.
