More important is what was happening before and after 1962.
India got its independence in 1947.
Except:
Piploda 1471 Sq Km
Jodhpur 93424 sq km
Junagadh 8643 sq km
Kashmir 101338 sq km
It took more than a year to get them into India.
In all 4,16,876 sq Km
Still left out were Portugal and French territories of Goa, Daman, Diu, Nagar Haveli, Pondicherry.
Total area added were:
Goa: 3702 Sq Km
Daman, Diu, Nagar Haveli: 603 sq Km
Pondicherry: 20 Sq Km
It meant another 4325 sq km
Total area added after August 1947: 4,21,201 sq Km
Still, net gain was nearly 4 lac sq km by Nehru.
And India was just 15 year old, still building up after doing many heroic things like mentioned above.
It had learned its lessons militarily too. Could identify friends n foes.
1967, India gave a befitting response to China on Nathu La and Cho La clashes at Sikkim border.
1971, India decapitated Pakistan into two and annexed 1,47,570 Sq Km of it to create a new nation Bangladesh.
Came 1999, India pushed back Pakistani forces from Kargil area of Ladakh.
So, in short, after the defeat in 1962, India never lost a war or ceded any area.
Summary: After 15th August 1947, India added 4,28,297 sq km to India; created a new nation with 1,47,570 sq Km and lost 43000 sq km.
Lost one and won 6 wars.
