that's patently false. The US and Taiwan believe that India will obliterate China just as the British and Americans believed that Nazi Germany would obliterate the USSR.
If they looked at the economic statistics, they would realize that any early gains Germany made, would be erased when the massive Soviet economy was put on a war footing. However, their racism against Eastern Europeans made them blind to the reality. Indeed, Nazi Germany lost the war the moment they invaded Poland in 1939, as that put them on a collision course with the #2 and #3 economies in the world (Britain and USSR). They could not fight a sustained war due to their poor economy and logistics.
Today, racism makes Americans and Taiwanese believe that India has an elite futuristic military equipped with the best Western weapons against Chinese using outdated 1950's Soviet arms. It is time to show them that India is actually late Qing at best, Iraq at worst.
