Have a look:
Nehru pleaded for US help against China in 1962 - Times Of India
India begged both the USSR and the USA to save them during the 1962 war.
But neither one came. Even though at that time (1960's) China was an enemy of BOTH the USSR and the USA, having recently fought the Korean war with America and the Sino-Soviet split with the USSR. Also, China at that time was just coming out of the worst famine in Chinese history (which only ended in 1961).
So despite them both being our enemies, and China being at its weakest point in history, neither the USA or the USSR came to save India.
Today, the USA is our largest trading partner, with their top officials calling for a "G-2" with China. And Russia is now our ally, and also a co-founder of the SCO along with China.
