9. India- China war The Indo- Sino war in 1962 changed the country's perception about non-violence forever.
The war is remembered for the humiliation of India's defeat, the betrayal by China of Hindi-Chini-Bhai-Bhai slogans and the devastating personal blow it dealt to Prime Minister Jawaharlal Nehru.
The invasion transformed our national mindset on matters military/defence for ever.
Never again - as the wars in 1965, 1971 & Kargil showed - would India be caught as unprepared.
